Screening for cancer?

 There are different types of cancer screening tests for men and women, and certain cancers can be screened for better than others.

THERE are several hospitals now advertising that they are offering cancer screening tests. I’m wondering if it is worth my while to get a check-up. What are cancer screening tests?
Cancer screening tests are tests that are done to try and detect cancer in people who have no symptoms or signs of cancer. In short, you are a healthy individual going for a medical check-up, and one of the plethora of tests that you may request for is cancer screening.
There are different types of cancer screening tests for men as opposed to women. Certain cancers can be screened for better than others.
Some tests are also more effective in detecting cancer than others. But it’s very important to detect cancer early, because at the early stages, some cancers can be cured. Or at least, you’ll have a far better chance of survival rather than if you detect it late.
What types of cancer screening tests are there? Do they all require taking my blood?

Cancer screening tests can be divided into the following:
·History taking – Here, the doctor asks you for family history of cancer or environmental factors which have been known to cause cancer, such as working in an asbestos-heavy environment. Breast cancer has a known genetic correlation, and it runs in families.
·Physical examination – The doctor then proceeds to examine you for signs of possible disease, such as a breast lump, lumps in other places, skin lesions or anything that seems out of the ordinary. A rectal examination may be done for men to look for enlargement of the prostate gland.
·Laboratory tests – Your blood, urine and maybe even tissue samples are then taken. Blood tests may include specific cancer markers. If you have a breast lump, it is advisable that you go for further investigations like a breast ultrasound and mammogram, and far more importantly, get the lump biopsied.
·Imaging tests – These include x-rays, ultrasounds, mammograms, CT scans, MRI and other such similar tests.
·Procedures – Some cancers are best detected by more invasive tests, such as a colonoscopy (procedure that allows the doctor to send a scope up your colon) to detect suspicious polyps or masses in your colon, which may or may not be cancer.
·Genetic tests – These look for certain gene mutations which are linked to certain types of cancer. 

What types of cancer screening are there for women? I have heard of the mammogram.
Breast self-examination is actually the commonest. By practising self-examination, you can detect warning lumps which you can act upon by going to see the doctor.
Mammograms are recommended for breast cancer screening, especially in women aged 40 to 70. By doing regular mammograms, studies have shown that this can decrease death related to breast cancer for women.
A mammogram is basically an x-ray of the breast. It is not a foolproof way of detecting lumps and such, especially in women below 50, because the breast tissue tends to be very dense. If a lump is detected, a mammogram is usually followed up with a breast ultrasound.
A Pap smear is a screening test for cervical cancer. It can also detect other cervical conditions, such as cervical dysplasia, which occurs more often in women aged between 20 and 30. A lot of these conditions may be precursors to cervical cancer, and so it is worth having a yearly Pap test if you are sexually active.

What about types of cancer screening for men?
A very common test is the PSA or Prostate Specific Antigen, which is not deemed to be that accurate as a cancer screening test.
The Prostate Specific Antigen (PSA) is a protein that is produced by the cells of the prostate gland. The PSA test is a blood test that measures this level in your blood.
The PSA is often elevated in men with prostate cancer. And until recently, it was a test that was recommended for all men aged 50 and beyond. However, more recently, it has been shown that some men with low PSA levels have prostate cancer, and some men with high PSA levels do not have prostate cancer.
Additionally, your PSA levels can fluctuate with factors such as prostatitis, urinary tract infection and prostate surgery. Apparently, only about 25% of the men who went for prostate biopsy after an elevated PSA turned out to have prostate cancer.

Is there any type of lung cancer screening?
A routine chest x-ray may detect a lesion or a shadow which can be further investigated. But this has not been shown to have decreased the death rate from lung cancer.
However, low dose spiral CT scans have been shown to decrease the death rate from lung cancer in heavy smokers if done routinely.
There is also the squamous cell carcinoma antigen, which can appear in many squamous types of cancers. It is better used as a monitoring factor in people who already have been diagnosed with squamous lung cancer.

Women, 47, forced to have leg amputated after discovering 'blood blister' is deadly cancer

A grandmother will have her leg amputated after developing what she thought was a blood blister. Ms Skelton, 47, has had primary lymphoedema, a chronic condition that causes swelling in the body's tissue, in her leg for more than 20 years. But when her leg began to bleed Vicki sought help first from her GP in April, then from her nearest accident and emergency department in Hull in July. 

 But it wasn't until last month that doctors told her she had a rare cancer. She was horrified to learn they would need to remove her left leg from above the knee to try and stop it from spreading.
Ms Skelton, from Hull, said: 'If I don't have my leg amputated, I will die. It started off as a blood blister and I think if they had known what it was, it might not have been like it is now and I might not be losing my leg. 'I have no choice and I'm gutted. 

After the operation, I have to have chemotherapy and, even after all that, they still don't know if it will be clear. 'They said the way this cancer works, it will go straight to the lungs. They are clear at the moment but you just don't know what's going to happen.'
Vicki is staying at Castle Hill Hospital in Cottingham and recent tests confirmed she had angiosarcoma, a rare cancer of the blood vessels, in her ankle. She claims her prognosis may have been better if services to manage the primary lymphoedema were available in Hull and the tumour in her leg had been detected sooner. 

 Primary lymphoema is caused by mutations in some of the genes responsible for the development of the lymphatic system. This results in problems in draining fluids from the body properly, and it is treated using massage and compression bandages. Vicki said there is a possibility of having an artificial limb in the future but the swelling due to her condition may make it difficult.

Exercise can help cancer sufferers beat the disease and stop it returning

Cancer patients can cut the risk of recurrence by half if they exercise, a number of studies have found. 

Despite the results the study also showed that many patients are reluctant to make efforts to keep fit and consider their daily activities sufficient exercise. 

The study is part of a series of investigations looking at exercise habits among cancer patients conducted by the Mayo Clinic in Rochester, Minnesota. 

‘As doctors, we often tell patients that exercise is important, but to this point, nobody had studied what patients know about exercise, how they feel about it and what tends to get in the way,’ says lead author Dr Andrea Cheville. 

For patients who have gone through breast or colon cancer treatment, regular exercise has been found to reduce recurrence of the disease by up to 50 per cent. The study, published in the Journal of Pain and Symptom Management, found that patients who exercised regularly before their diagnosis were more likely to keep up their routines afterwards.

Untrue Health Warning - Scratch Card 'Silver Nitro Oxide' Coating Causes Skin Cancer

Text message warns people not to use fingernails to scratch off the coating on scratch tickets because the coating contains a substance called "Silver Nitro oxide" that can cause skin cancer.

The information in the warning message is untrue. The coating on scratch tickets is made of specialized latex inks. There are no credible references to a compound called "Silver Nitro oxide". 

There are no credible medical or scientific reports that suggest that scratch ticket coating has been linked to skin cancer. There are no credible references to an organization known as the "Medical Research Authority of the US". The warning is a hoax and should not be forwarded. 

The coating on scratch tickets is not made from a substance called 'silver nitro oxide'. In fact, I could not find any evidence that such a compound even exists. There are two chemical compounds with similar names. One is Nitrous oxide, more commonly known as laughing gas, which has been used as an anesthetic in medical procedures since the 1840's and is also used in rocketry and to enhance engine power in motor racing.

 The other is Nitric oxide, a diatomic gas that plays a role as a cell signaling molecule in mammals and is also used as an intermediate in the chemical industry. Neither of these compounds is used to create the coating on scratch tickets. In fact, the coating is created from specialized latex or UV inks. A technical article about the material used in such coating published on Quora notes:
The material is known as a UV ink. Not the ink that becomes visible under UV light as is referred to on Wikipedia, but an ink that 'dries' under UV radiation.

UV inks are essentially a mixture of colored monomers and oligomers (the individual chemical units that eventually form 'polymers' ) and reaction 'photo-initiators' that become active when exposed to UV radiation. The monomers and oligomers form a viscous liquid, thus serving simultaneously as the 'pigment' and 'solvent' of a conventional ink; they do not need an organic solvent as a fluid base, and do not 'dry' in air like typical solvent-based inks. On exposure to UV light, the initiators set off the polymerization reaction, rapidly cross-linking the monomers and oligomers into a solid 'plastic' polymer, in a process known as 'curing'. This polymerization process also inspired the alternative naming of UV inks as 'latex inks'.

[.....]

The production of scratch-off tickets is a two-step process - a substrate is covered by a thick, smooth layer of UV ink coating, and then printed with a special 'scratch-off' black/silver UV ink (scratch-off inks can sometimes be solvent-based ). An optional third step could involve printing text or images over the scratch-off area, with yet another type of UV ink.
There is no mention of a chemical called silver nitro oxide being used in these UV inks. Nor are there any credible reports that suggest a link between inks used on scratch tickets and cancer.

Furthermore, there are no credible references to an organization known as the Medical Research Authority of the US. The closest I could find is the US based Biomedical Advanced Research and Development Authority (BARDA). But, not at all surprisingly, there is no information on the BARDA website that supports the claims in this hoax message in any way.

Scratch tickets of various types are these days just about everywhere. On any one day vast numbers of people in dozens of countries are likely to be happily scratching away, often using their fingernails as scratching tools.
 So, of course, any credible link between scratch ticket coating and cancer - even a tenuous one - would have certainly been widely publicized by the main stream media and medical authorities. In reality, there is nary a trace of such media or medical reports.

Risk of Breast Cancer High in Women Who Conceive by Using Fertility Drugs

A new study conducted by researchers at National Institutes of Health has found that the risk of breast cancer in women taking fertility drugs goes up when they get pregnant.

 There have been a number of studies looking into whether fertility drugs play a role in reducing or increasing the risk of breast cancer in women and the conclusions have been mixed with some studies claiming that they do increase the risk and some claiming that they reduce the risk. 

 Researchers at NIH observed 1,400 women diagnosed with breast cancer before the age of 50 years and compared them with 1,600 of their sisters who had no signs of the disease. Around 288 participants admitted to taking ovulation-stimulating fertility drugs, 141 of whom had pregnancy lasting 10 weeks or more after taking the drugs. 

 The researchers found that those who took the fertility drugs and did not get pregnant had a lower risk of being diagnosed with breast cancer under 50 years of age compared to those who got pregnant.

 “Our data suggest that exposure to a stimulated pregnancy is enough to undo the reduction in [breast cancer] risk associated with a history of exposure to ovulation-stimulating drugs”, the researchers wrote in the report, published in the Journal of the National Cancer Institute.

Teenager, 19, who thought her watery eye was caused by make-up discovers it is CANCER tumour behind her nose



When Tasha Jilka began suffering from a watery left eye, she put the strange symptom down to her make-up or the seasonal weather.

But far from being an innocuous allergic reaction to cosmetics, the teenager's bizarre ailment was one which changed her life forever, as she was later diagnosed with cancer.

The 19-year-old's watery eye was caused by a rare cancer tumour called olfactory neuroblastoma at the back of her nose which left doctors eventually having to rebuild her whole face.

Tasha's rare diagnosis was eventually made a year after she first suffered the watery eye, having been missed by doctors and opticians.

Her ordeal began in May 2008, when, aged 16, her symptoms began.

Tasha, from Leicester, said: 'My left eye was very watery but I just put it down to make-up. It kept getting worse and I decided to go to my GP.

'It was put down to a cold and the weather and I was told it would go by itself.

'I went back a few times when it didn’t get better and was referred to an optician, but they couldn’t find anything either.'

Four months later, her eye had got worse and she was referred to a Cambridgeshire hospital, as she was living near there at the time.

Tasha had an operation to clear a blocked tear duct - but it still did not solve her problems.
In 2009, when she and her family moved to Leicester, she again went to her doctor and was referred to specialists at Leicester Royal Infirmary.

Tasha said: 'I had a similar eye test but this time doctors also looked up my nose and could see a lump.'

A biopsy was taken and a short time later, Tasha’s cancer was diagnosed.

She said: 'When I was told it was as if they were talking about someone else. I knew it was serious.

'I thought it was a little lump in my face but the news began to sink in.'

In May 2010 Tasha had surgery to remove the tumour.

It was so severe that surgeons had to reconstruct her nose and she is still having problems with the vision in one eye.

Taller women 'at greater risk of ovarian cancer'




Tall women are more likely to develop ovarian cancer than their shorter friends, research suggests.

Oxford University scientists reviewed 47 studies involving more than 100,000 women – many of them with ovarian cancer – and found a link with height.

They also found the disease is more common in overweight women.

Every two inches in height increased the odds of developing the disease by seven per cent.

The researchers said tall women could simply have more cells that can become cancerous.

Growth hormones may also play a role, the journal PLoS Medicine reports


Dr Paul Pharoah, a Cambridge University cancer expert, said while the analysis was valid, the impact on individual women would be small.

Researchers say that with women in the Western world gradually getting taller as well as fatter, it is important to make the link.

But others urged tall women not to worry, saying their overall odds of developing the disease are still small.

Ovarian cancer is the fifth most common cancer in women, with more 6,500 cases diagnosed each year in the UK.

Two-thirds of these die from the disease, because it is often symptomless in its early stages and not spotted until it has started its poisonous spread around the body.

Age and not having had any children are known to increase the odds of the disease, while the contraceptive pill helps protect against its development.

But previous attempts to look at the role of height and weight have provided inconsistent results, so researchers decided to put together as much information as they could on the topic to come up with an answer.

Every extra two inches in height raised the odds of the disease by 7 per cent.

The finding held true even when other factors such as age and use of the pill were taken into account, the journal PLoS Medicine (MUST CREDIT) reports.


The researchers aren’t sure what’s behind the link but say it may simply be that tall women have more cells that can become cancerous.

Growth hormones may also be important.

The study also found that the heavier and more obese a woman was, the greater her risk of ovarian cancer, but only if she had never been on HRT.

Dr Paul Pharoah, a University of Cambridge cancer expert, said that while the analysis was done well, the impact on individual women will be little.

To illustrate his point, he compared a woman who is 5ft tall with one who is 5ft 6in in height.

The shorter woman will have a 1.6 per cent chance of developing ovarian cancer in her lifetime, the figure for the taller woman will be 2 per cent.
He added that there are many other good reasons for a woman to maintain a healthy weight.
Researcher Professor Valerie Beral described the link with height as ‘curious’.
She said that with extra inches also raising the odds of other cancers, including br*ast cancer, it is important to pin down what is at the root of the link.

Coke, Pepsi make changes to avoid cancer warning


Coca-Cola Co. and PepsiCo Inc. are changing the way they make the caramel coloring used in their sodas as a result of a California law that mandates drinks containing a certain level of carcinogens bear a cancer warning label.

The companies said the changes will be expanded nationally to streamline their manufacturing processes. They are already in effect to comply with the California law.

Coca Cola and Pepsi say their drinks have always been safe and that their sodas will not taste any different.

A Food and Drug Administration spokesman noted that a consumer would have to drink more than 1,000 cans of soda a day to reach the doses administered that have shown links to cancer in rodents.

I thought I was pregnant but my 'bump' was a melon-sized TUMOUR

Kayleigh Terry now hopes to start a family after recovering
 from having a melon-sized cancerous tumour

A secretary who thought she was pregnant with her first child after piling on the pounds was terrified to discover she actually had cancer.
Kayleigh Terry, 21, had also been suffering from pains and fatigue but was bemused when a pregnancy test came back negative.

A follow-up ultrasound scan revealed she had a large cancerous growth which covered an area from her br*ast to her lower abdomen.
She was diagnosed with Ewing's Sarcoma and had emergency chemotherapy to shrink the potentially deadly tumour.

Kayleigh lost her hair and eye-lashes along with 3st in weight after the shrunken tumour was removed a few months later.
But today after a gruelling two year battle, Kayleigh is celebrating after being given the all-clear and even hopes she may be able to start a family in the future.

Kayleigh of Warrington, Cheshire said: 'I thought I was going to be a mother and I never thought for one moment I had a tumour growing inside me. It just looked for all intents and purposes like a baby bump.
'I just couldn't believe it when I found out what it was. I'm just so relieved to be alive and hopefully I will have children in the future. I'm so excited for everything now. I can't wait to see what 2012 brings.'
Kayleigh was diagnosed with the condition just days after her 19th birthday in July 2009. The teenager was lying in her garden sunbathing at her own barbeque birthday party when her friends commented how far her usually flat belly was protruding.
Kayleigh said: 'It was my 19th Birthday party. I should have been eating cake, I could hardly even manage a sausage, yet my stomach was massive. It didn't make sense.'

The month before the diagnosis she had suffered severe stomach pains, fatigue, loss of appetite and a rapidly growing stomach, and the pains were often so bad that she had resorted to taking hot baths in the early hours of the morning.
Kayleigh said: 'I'd been to the doctors and they said it was something to do with my bowels. Pregnancy entered my mind as I had a boyfriend, but I was on the pill, and as soon as my tummy started to grow I did a test but it was negative.'
Kayleigh then went to her GP complaining of intense stomach pains, underwent blood tests and an ultrasound scan and was told to expect the results in a few weeks, but just days later she received a call.

Kayleigh said: 'I couldn't make it into work the week after, the pains were so excruciating. I was shocked when I received a phone call so quickly about a week later telling me I had to come in.
'I was even more shocked when they showed me my ultrasound and the massive mass on the screen. I'd read about tumours and cancer and asked him if it could be that, he said they weren't ruling cancer out but had no idea what it was inside of me.'

Kayleigh was referred to a specialist at Clatterbridge Centre for Oncology in Wirral, Merseyside who broke the news that she had cancer and required urgent treatment.
Kayleigh said: 'The day I went to see the specialist I was so ill, I'd already been sick, He diagnosed me there and then with Ewings Sarcoma - a rare type of Cancer - and told me I wouldn't be going home. I was in another world and not really with it.'
Kayleigh was told that the tumour had developed suddenly in her soft tissue, rather than bone as was usually the case, and due to its location she would have to begin chemotherapy within 24 hours.
The specialist warned she may not be able to have children afterwards and gave her the option of freezing her eggs, but said this would delay the important treatment.
Kayleigh endured an initial two months of chemotherapy at the Clatterbridge Centre for Oncology, to reduce the tumour from the size of a 'melon' to that of 'a lime' followed by a further four months before it was removed in January 2010.
She endured a further six months of chemotherapy after the operation and spent around a year in and out of hospital altogether, followed by regular three-monthly check-ups.
Kayleigh celebrated the birth of her nephew, Addison in September before moving in with boyfriend Adam in November and, after being officially given the all clear last month, she is now looking forward to a bright future with her family.
Dr Nasim Ali who treated Kayleigh said: 'Kayleigh has had a tumour from the Ewings family of tumours. These behave aggressively and require intensive chemotherapy treatment for a significant length of time, often in addition to surgery.
'Kayleigh was extremely courageous and positive throughout her treatment and from the start has had a positive response to her therapy.
'She remains well at this time and will continue to remain under follow up at Clatterbridge Centre for Oncology for several years.'

Types Of Cancer: Symptoms And Management

Globally, the month of October is used to create awareness on br*ast cancer. According to estimates, over 1.38 million new br*ast cancer cases are diagnosed annually with 458, 367 deaths worldwide annually. One of the keys for treating br*ast cancer is catching it very early on, experts say. 

This month aims to promote women’s awareness of the disease and encourage mammogram screening which has become much more accurate at detecting early states of the disease. Many non-governmental organisations and the Federal Ministry of Health are of the opinion that the fight against br*ast cancer should be taken to the public at large. 

Events are held around the country in October, including walks and other fund-raising activities, that not only promote br*ast cancer awareness but also seek to raise money to provide all women access to healthcare and br*ast screening. The issue is certainly worth paying attention to, with figures showing alarming rate of a million new cases of invasive br*ast cancer this year with approximately 20% dying from the disease, it is not to be taken lightly. 

Br*ast cancer is the most common form of cancer in women, and surprisingly, it can also occur in men, though the number of cases is well under one percent and less than 500 males will die from the disease in 2011. Apart from having regular screenings and being generally aware of br*ast health, other factors that women should be aware of include:

Post menopausal
weight gain
Family history of the disease
Getting yearly mammograms after the age of 40 Arguments that are commonly heard include ideas that people rather wouldn’t know if they have cancer so avoid screenings, as well as not bothering because they feel healthy. 

Two aspects that women should be aware of is the possibility to make regular self examinations once a month, and on a positive note, being clear that br*ast cancer survival rates are improving both from more cases being caught early on and treatments and technologies becoming more advanced. Br*ast cancer survivors generally have a good quality of post-treatment life and many go on to live happy and healthy lives, having overcome the disease. 

 Having this kind of information made clear is one of the primary goals of Br*ast Cancer Awareness Month. However, the four most common cancers are: Br*ast Cancer, Colon Cancer, Lung Cancer, Prostate Cancer . Cancer is a broad term that encompasses over one hundred different types of cancer. Although each type has its own set of characteristics, there are some cancer symptoms that occur in many types of cancer. 

It is important to note that some types of cancer do not present any symptoms until they are in advanced stages. This is why cancer screening and risk assessment are vital for cancer prevention and early detection, medical journals said. For most people with cancer, a persistent symptom is what prompted them to seek medical attention that eventually led to a cancer diagnosis. 

A 47-year-old Anayo Okechukwu, said he had severe drenching night sweats, severe heartburn, and a severe host of pains in the stomach, lower back pain, shoulder pain, difficulty swallowing sometimes, and a drastic weight loss. Currently living with liver cancer, Andrew presented with a noggin on his thyroid with a tumor that is growing and spreading. “So my symptoms were real,” he says, “I’m sad and I’m not afraid. I only feel afraid for my children ages 17, 15, 16 and 11. They will need me and I fear what they will fear or go through. I’m tired. 

I just want to make sure that I’m comfortable. No more pain” he says. Another victim who refused his name on print, said, “I have had soft tissue sarcoma since age 21. It has been removed five times but spread to my liver five years ago. I have been having bad back, chest and hip pain. I have lumps and bumps all over. I feel tired all the time, and I can’t handle any weight on my body at all. The hip pain causes me to not be able to sleep well, hurts to have s*xual intercourse. In fact, I hurt every day. 

Five years ago, I was diagnosed stage four but have always been told they don’t know the primary source. I am hurting alone and scared to death” A medical expert, Dr Okunoghae Imafidon, offers hope and succor to the sufferers of cancers, saying, “There is life after death. If you or your family are struggling with the possibilities of having cancer, stay positive and exercise, even more importantly read God’s Word. The Bible says it will give strength to thy navel and marrow to thy bones. 

Read the book of Psalms and Romans. He is the only one who gives true peace” Musa Abu tells his own story. “I am a smoker of about 30 cigarettes a day, and have been smoking for a good 25 years, I am a female. I always feel extremely exhausted, although my line of work is very physical. Of late I have developed a pain in my chest, not serious but it is always there. My legs are aching in and behind the joints, especially when I have been lying down or sitting and I get up, and I suffer from very bad headaches on a daily basis. 

A friend of mine passed away last year with pancreatic cancer and one of her symptoms was the sore legs, do you think I need to be checked?” For ovarian cancer, it is always characterized with abnormal bleeding, according to doctors. Mrs Victoria narrates her experience, “I did not know I had gone through the menopause. I still thought I was having periods when in fact I had womb cancer. 

I am due to have my womb removed. Apart from the bleeding, which still occurred roughly monthly, I felt a little tired, so I thought that at 59, I may have made medical history by being one of the oldest menstruating women because of the way the bleeding was occurring, monthly. But no, I did get a very nasty shock after having a biopsy and within one month of seeing my doctor and having my hospital tests, I had my operation in five days time. 

I will not deny I am a little frightened, but fingers crossed that it is contained in the lining of my womb” Another says, “It turns out that I have small-cell cancer in the lung and liver. It is spreading fast. There is little they can do to slow it down, and there is no stopping it at all. I am terminally ill. By the time I found it out, I was a stage 4.” Also, cancer knows no age barrier as a student laments his fate “I have had a sinus infection for four months now. 

It never gets better and every doctor I have seen just prescribes antibiotics that never seem to help. Now I’m having pain in my left side in and under my ribs, I always feel like I’ve eaten a truck load of food, fatigue, I’m impossibly cold all the time, my glands in my neck are always swollen and sometimes hurt so bad that my teeth ache and I’m having my period every two weeks. 

I also have a rash that doesn’t itch or hurt on my arms and legs. I can’t seem to get any doctor to want to find out what is causing all this. They just throw antibiotics at me and send me on my way. Nobody believes me because I’m young and supposed to be healthy but clearly I’m not. Not even my roommate believes me and he’s been present for all of this stuff. I am so aggravated and worried about myself. How do I get them to listen?” Speaking on the early symptoms of lung cancer. Okunoghae says, “We know that the survival rate from lung cancer is better the earlier it is caught. 

The 60% to 80% 5-year survival rate with stage 1 lung cancer drops to a saddening 10% with stage 4 diseases, yet nearly half of people has progressed to this advanced stage at the time of diagnosis.” Significantly, he said one should keep in mind that understanding the early symptoms of lung cancer is important for non-smokers as well as smokers. According to World Health Organisation estimates, currently, 50 per cent of people who develop lung cancer are former smokers, and 15 per cent have never smoked. 

Many people dismiss or adapt to a chronic cough, attributing it to something else. Perhaps it is allergies, a “leftover” cough following a cold, or dry air during the winter months. But, the Oncologist noted that a cough that lasts more than a few weeks can be a sign of something else. “A chronic cough as an early symptom of lung cancer is even easier to miss if you have a condition that predisposes you to coughing, such as asthma, COPD, allergies, or gastroesophageal reflux. 

Coughing up blood (hemoptysis) is a common symptom of lung cancer, but can be fairly subtle and you may notice only a small amount of blood tinged phlegm when you cough. If you experience a persistent cough, check with your doctor, and ask for a second opinion if you don’t get a clear answer.”


There are four standard methods of treatment for cancer: surgery, chemotherapy, radiation therapy, immunotherapy and biologic therapy. Clinical trials may be an option for some as cancer treatment who meet certain study criteria. 

When initially diagnosed with cancer, a cancer specialist, an oncologist, will provide you with the cancer treatment options. He or she will recommend the best treatment plan based on your type of cancer, how far it has spread, and other important factors like your age and general health. Ultimately, you are the one who makes your treatment decisions based on your doctor’s recommendations, possible second opinions, and other information gathered from qualified professionals. 

Surgery: Surgery can be used to prevent, treat, stage (determine how advanced the cancer is), and diagnose cancer. In relation to cancer treatment, surgery is done to remove tumors or as much of the cancerous tissue as possible. It is often performed in conjunction with chemotherapy or radiation therapy. For those whose cancer is not treatable, palliative surgery may be an option to relieve pain that may be caused by the cancer. Palliative surgery is not intended to treat or cure the cancer, or even to prolong life, but more to lessen discomfort. 

Chemotherapy: Chemotherapy is a type of cancer treatment that uses drugs to eliminate cancer cells. Unlike surgery, chemotherapy affects the entire body, not just a specific part. It works by targeting rapidly multiplying cancer cells. Unfortunately, other types of cells in our bodies also multiply at high rates, like hair follicle cells and the cells that line our stomachs. This is why chemo can cause side effects like hair loss and an upset stomach. 

Chemotherapy is most commonly given by pill or intravenously (IV), but can be given in other ways. A single type of chemotherapy, or a combination of drugs, may be prescribed for a specific length of time. Like surgery, chemotherapy can be prescribed alone, in conjunction with radiation therapy or biologic therapy. 

Radiation Therapy: Radiation therapy uses certain types of energy to shrink tumors or eliminate cancer cells. It works by damaging a cancer cell’s DNA, making it unable to multiply. Cancer cells are highly sensitive to radiation and typically die when treated. Nearby healthy cells can be damaged as well, but are resilient and are able to fully recover.

Cancer drug resistance clue found

It may be possible to extend the usefulness of cancer drugs by preventing drug resistance in tumours, say researchers. A study, published in Science Translational Medicine, showed a chemical reaction went into overdrive as resistance developed. Scientists said drugs were already on the market which interfered with the process. Cancer Research UK said the field offered "tremendous optimism.

 An international team of researchers were investigating the cancer drug cetuximab, which is used to treat colorectal cancer, head and neck cancers and some lung cancers. It targets a protein - epidermal growth factor receptor (EGFR) - which drives tumour growth. They said "all patients will ultimately develop resistance to cetuximab" but that little was known about how the resistance developed.

In this case, the tumours replaced the EGFR route with one involving a different protein - ERBB2 - and continued to grow.

 Dr Pasi Janne, from the Dana-Farber Cancer Institute in Boston, said: "ERBB2 activates a critical signalling pathway that is not normally blocked by cetuximab, and in this way subverts cetuximab's function. "Because ERBB2 isn't affected by cetuximab, this is an easy way for cancers to become resistant to the drug." The researchers said several drugs which target ERBB2 had already been approved so "the findings from the current study can be used to design potential clinical therapies". However, they caution that there are likely to be other ways that cancers can develop resistance. 

 Henry Scowcroft, science information manager at Cancer Research UK, said: "Unfortunately, patients' tumours can become resistant to treatment, and understanding why this happens is a major challenge in cancer research. "This new study is a great example of how researchers are uncovering the molecular tricks cancer cells use to evade treatment, and finding out how to stop them doing so. "Research like this gives us tremendous optimism that we're on the cusp of a real revolution in cancer, although there's a lot more work to do to make this a reality."

Tamoxifen Gives 15-Year Br*ast Cancer Protection

Study Shows 1/3 Lower Death Risk From Br*ast Cancer 15 Years After Tamoxifen Treatment
Five years of tamoxifen treatment -- with or without chemotherapy -- cuts a woman's 15-year risk of br*ast cancer death by about a third.

The reassuring finding comes from analysis of long-term data on 21,457 women with br*ast cancer enrolled in clinical trials of tamoxifen.

"Substantially reduced mortality rates for br*ast cancer continue well beyond year 10, as a delayed effect of the greatly reduced [br*ast cancer] recurrence rates during years 0 to 9 [after about five years of tamoxifen therapy]," report Christina Davies, MD, and colleagues in the international Early Br*ast Cancer Trialists' Collaborative Group (EBCTCG).

One reason br*ast cancer is so deadly is that it often comes back after what a woman had hoped would be curative treatment. Tamoxifen reduces this risk.

This means many women's br*ast cancers are cured, suggest Stephen K. Chia, MD, of the University of British Columbia and Antonio C. Wolff, MD, of Johns Hopkins University, in an editorial accompanying the EBCTCG report in the July 29 online issue of The Lancet.

"Five years of tamoxifen can prevent a high proportion of recurrences and potentially cure many patients, rather than simply delay an inevitable event," Chia and Wolff note.

Tamoxifen works only on the most common form of br*ast cancer: the form that needs the female hormone estrogen in order to grow. These cancers carry proteins, called receptors, that bind estrogen. Tamoxifen makes it impossible for these receptors to bind estrogen.

Importantly, the EBCTCG study shows that tamoxifen works even on br*ast cancers that carry only small numbers of estrogen receptors.

"Therefore, another crucial message from this [study] is the need for accurate and sensitive [tests] ... to detect even low concentrations of estrogen receptor and thus further identify potential candidates for ... tamoxifen treatment," Chia and Wolff suggest.

Newer drugs, called aromatase inhibitors, also block estrogen. But these drugs don't work in premenopausal women. Moreover, it's still not known how long their benefits last.

"Access to accurate estrogen-receptor testing, and to tamoxifen (a relatively inexpensive drug) or other endocrine therapies is a public health imperative for all women with br*ast cancer," Chia and Wolff conclude.

Cellphones don't increase cancer risk in kids, study says

Using cellphones doesn't increase children's cancer risk, according to a new study, the latest in a series of papers that find no link between the phones and brain tumors.
Scientists say the study is important, because it is the first of its kind to focus on children.
The study's authors compared the cellphone habits of nearly 1,000 children in Western Europe, including 352 with brain tumors and 646 without. Kids who used cellphones were no more likely to develop a brain tumor than others, according to the study of children ages 7 to 19, published online Wednesday in the Journal of the National Cancer Institute.
Scientists have been eagerly awaiting these results, says Martha Linet, a doctor with the National Cancer Institute who wasn't involved in the study. "It's very reassuring," Linet says.

Researchers, led by Denis Aydin of the Swiss Tropical and Public Health Institute, looked at their data in several ways, searching for possible trends with long-term use. They found no increase in brain tumors among children who had used cellphones for five years or more, according to the study, funded by European health agencies.

Some scientists and consumers have been concerned about cellphones' health effects, especially on developing children, because cellphones emit energy close to the brain.
In the study, Aydin and colleagues note that radio frequency electromagnetic fields created by cellphones penetrate deeper into children's brains than adults' brains, mainly because kids' skulls are smaller, the study says. Recent studies have suggested that small children's brains absorb about twice as much mobile phone energy as adults' brains.
But authors also point out that this energy — unlike the radiation given off by X-rays or CT scans — isn't strong enough to damage DNA, cause mutations and lead to cancer. And while many people are concerned about cellphones, no one has ever come up with a way to explain how the devices might cause cancer, Linet says.
If cellphones caused brain tumors, researchers might expect to find those tumors on the side of the head where kids hold their phones. In the new study, however, children had the lowest risk of tumors in the part of the brain exposed to the most cellphone energy, write scientists John Boice and Robert Tarone in an accompanying editorial. They note that there has been no increase in brain tumors — among kids or adults — since cellphones came into widespread use in the 1990s. In their editorial, they note that there were 285 million cellphone subscribers in 2009 in the USA alone. If cellphones really did cause brain tumors, doctors would likely have noticed this by now, they write.
But the study also produced some mixed signals.
In a subset of children, researchers found a higher risk of brain tumors in children whose cellphone subscriptions had begun more than 2.8 years ago.
Overall, however, parents should find these results reassuring, says pediatrician Rachel Vreeman, of the Indiana University School of Medicine, who summarizes recent cellphone research in her book, Don't Cross Your Eyes… They'll Get Stuck That Way!: And 75 Other Health Myths Debunked.
"This is a good piece of evidence that parents don't need to be panicked about cellphones and cancer," Vreeman says.
Concerns about cellphones were renewed last month, when a branch of the World Health Organization, the International Agency for Research on Cancer, reversed its previous position. In the past, the agency had said there was "no conclusive evidence" linking cellphones to brain tumors. Now, the agency classifies cellphones as "possibly carcinogenic" based on "limited evidence," acknowledging that the few links between cellphones and cancer could be due to chance.
The "possibly carcinogenic" category includes a number of staples of everyday life, however, such as coffee, pickles and styrofoam, Vreeman says.
"Scientific evidence has overwhelmingly indicated that wireless devices do not pose a public health risk for adults or children," said John Walls of CTIA-The Wireless Association, in a statement.
Consumers who remain concerned can take a number of steps to reduce their exposure to cellphone energy, such as using a hands-free device or a speakerphone, the American Cancer Society says.(www.todaysgist.com)
