Obesity and Cancer Risk

According to the National Cancer Institute, obesity is a condition in which a soulfulness has an abnormally high and unhealthy proportion of body fat. Obesity is measured by calculating a persons BMI. Years of research stir that there are connections between obesity and cancer risk. Research shows us that an increase in body weight increases insulin levels in the blood, which promote the development of original tumors and tumor regulators. Fat cells also produce adipokine hormones, which stimulate cell growth.Leptin, which is abundant in obese people, acts on a receptor on the brain where a person exhibits appetite and promotes cell proliferation, or cell growth. Essentially, excess body weight is the catalyst for hormones in the body to not function properly charm additionally promoting cell growth, which is the major cause of cancer spread. In 2007 research found 34,000 new cases of cancer in men and 50,500 new cases in women ascribable to obesity. It is estimated that 15 canc er related deaths are due to overweight and obesity.Obesity is associated with several cancers in the body, including in the esophagus, pancreas, colon and rectum, kidney, thyroid, gallbladder, breast (after menopause) and endometrium (the lining of the uterus). Weight extend to affects the bodys immune system, certain hormones including insulin and estrogen, and factors that regulate cell division. Scientists in the American Cancer Society admit that research is limited in skill whether or not weight loss can reduce cancer risk.There is growing evidence to suggest that a reduction in weight may diminish the risk of breast cancer, after menopause, as well as more aggressive forms of prostate cancer. However, obese people who lose weight oftentimes reduce certain hormone levels that relate to cancer risk, such as insulin and estrogen.
