More than a third of adults and youth in the U.S. are obese, according to a recent Journal of the American Medical Association study. While research shows obesity can increase risk for heart disease, stroke, diabetes, and cancer, a new U.K. study published in the The Lancet took a closer look at exactly how dangerous obesity can be.
Researchers from London School of Hygiene & Tropical Medicine and the Farr Institute of Health Informatics investigated the medical records of more than 5 million adults in the U.K. between 1987 and 2012 to see how obesity affected cancer. The researchers found 166, 955 people developed cancers of interest during follow-up, and that body mass index (BMI) was positively associated with 17 of the 22 cancers that the patients had.

For every 5kg/m2 of BMI increase, there was a 62% increase in the risk of cancer of the uterus, 31% higher risk in gallbladder, 25% increase in kidney, 19% in liver, and 10% or less of colon, cervix, thyroid, post menopausal, ovarian, and leukemia.
Since premenopausal breast cancer and prostate cancer risk was lower with high BMI in some study participants, there’s more to developing the cell abnormality than having a big waistline. Nonetheless, it’s safe to say that eating clean and exercising regularly will reduce your risk of at least 10 common types of cancer.
The role of exercise and diet in preventing obesity has never been so prominent since this is the largest known study to examine the effects of obesity on cancer rates. Beat the odds by breaking a sweat!
