Increased obesity increases likeliness of cancer, study
Posted on: 29/Aug/2016 5:41:39 PM
There are a number of studies and researches that stand evident of the fact that obesity or overweighing increase the likeliness of about 13 types of cancer. As a part of the World Health Organization, the International Agency for Research had conducted a study on cancer.
There prevailed very strong evidence on how overweight or obesity leads to five types of cancer. This includes breast cancer in postmenopausal women, kidney or uterine cancer, adenocarcinoma of the esophagus ad colorectal cancer.
In this new study, the results of which was published in The New English Journal of Medicine, brings a link between obesity and eight different types of cancer. This includes gastric cardia which is the cancer in a part very close esophagus and stomach; cancer in the gallbladder, pancreatic cancer, ovarian cancer, thyroid cancer, meningioma, benign type of cancer in the brain, blood cancer and multiple myelomas.
Dr. Graham Colditz, a professor of medicine and surgery, Washington University in St. Louis, the chairman of the working group said these thirteen kinds of cancer contribute to over 42 percent of most of the recent cancer diagnoses.
Colditz added that the only environmental factor affecting cancer is smoking. This is a very important fact for the non-smokers. Now, what tops the list of things to be focused is obesity.
There is intense significance of metabolic and hormonal abnormalities associated with chronic inflammation.
Elizabeth A. Platz, who is out of this report, but a widely published cancer researcher stated that the most strong association observed in the study was with the uterine cancer. Postmenopausal breast cancer is largely caused due to obesity too, particularly estrogen receptor positive cancer. Women out there need to listen to these. So far, most of the researches done are observational. They do not give concrete reason for the cause or effect, despite the fact that researchers considered evidence for association of this kind. There are studies that also studied the level of risk in adult who weighs normal with a BMI of 18.5 to 24.9.
The fatter a person is, the higher will be the risk of cancer - this is applicable for a few kinds of cancer. For instance, as compared to normal weighing women, those with BMI of the range 25 to 29.9, the risk of endometrial cancer is 50 percent higher. At the same time, the risk gets doubled in women whose BMI range between 30 and 34.9 which in turn gets quadrupled in women with 35 to 39.9 as BMI. There is seven times higher risk of endometrial cancer in women whose BMI is 40 as compared to those whose BMI is normal. In the study, there were just limited evidence about the association of obesity with male breast cancer, diffuse large B-cell lymphoma and prostate cancer.
