Obesity Linked to 11 Types of Cancer
Numerous studies have shown that obesity increases cancer risk, and now, researchers have discovered a strong connection between obesity and certain types of malignancies. Cancer is the leading cause of death worldwide and, according to the World Health Organization, 1.9 billion adults in the world are overweight or obese.
Researchers analyzed 204 previously published studies that explored obesity, weight gain, waist size, and 36 different types of cancer—looking for evidence of a strong link between obesity and the specific cancer type. They found the strongest connections between obesity and cancer of the digestive tract and hormone-related cancers in women.
According to researchers, high BMI—body mass index, a ratio of height to weight—increases the risk for cancer of the esophagus, stomach, bone marrow, biliary tract system, gallbladder, pancreas, kidney, colon and rectum, and endometrium (lining of the uterus) and ovaries in women. Weight gain and excess belly fat after menopause is also associated with an increased breast cancer risk.
