Obese, overweight people vulnerable to Eight types of Cancer
Scientists have found an interrelations between obesity and eight different kinds of cancer
International Agency for Cancer on Research (IARC), which is a part of World Health Organisation had recently conducted an examination on 1,000 cases of obesity in reference to the risk of cancer. Prior to this study, an analysis in 2002 by a different team in the same organisation, had proved that being overweight or obese can cause oesophagus, breast, colon, uterus or kidney cancer in women during their postmenopausal phase.
In light of the new research that has been undertaken by IARC, it has been brought to notice that being overweight can increase the risk of eight more kinds of cancer, in addition to the types that had been mentioned in the analysis. The study has found that middle-aged, overweight or obese people are prone to developing pancreas, liver, gall bladder, thyroid cancer, blood cancer, multiple myeloma, meningioma (which is a kind of brain cancer), stomach cancer and ovary cancer. Combining the old research with the new, there are, now, a total of eighteen types of cancers that the overweight population is highly vulnerable to.
This research has been published in The New England Journal of Medicine and it states that excess of body fat may be the cause of eight other kinds of cancer as "sufficient evidence" underlines. The team of 21 international experts, working independently, have also highlighted that body mass index (BMI) is directly propositional to the risk of acquiring one of the eighteen cancer. That is, higher the BMI, higher is the risk of an overweight person to be diagnosed with cancer.
It has also been mentioned in the research that "limited evidence" points towards the fact that chances of death due to one of the type of Lymphoma, prostate cancer and breast cancer (in men), are relatively low in people with average weight.
The lead doctor on the research, Dr. Beatrice Lauby-Secretan has said "This comprehensive evaluation reinforces the benefits of maintaining a healthy body weight in order to reduce the risk of several different types of cancer,".
Additionally, the doctor who chaired this specific group from IARC and is an expert of cancer prevention at the Washington University School of Medicine, United States, Dr, Dr Graham Colditz, expresses "The burden of cancer due to being overweight or obese is more extensive than what has been assumed."
"Many of the newly identified cancers linked to excess weight haven't been on people's radar screens as having a weight component."
"Lifestyle factors such as eating a healthy diet, maintaining a healthy weight and exercising, in addition to not smoking, can have a significant impact on reducing cancer risk."
"Public health efforts to combat cancer should focus on these things that people have some control over."
Considering the facts that, more than 68.8% of the adult US population and 61.7% of adult UK population is overweight, the risk of cancer runs higher than ever.
