Research has shown a definite link between weight and certain types of cancer.

Obesity is a proven cause for cancers of the colon, breast (post menopause), endometrium (the lining of the uterus), kidney, and esophagus. While the evidence is less strong, excess weight is also linked with cancers of the gallbladder, ovaries, and pancreas. The World Cancer Research Fund and American Institute for Cancer Research has concluded that about one-third of cases of the most common cancers in higher-income countries could be prevented through diet, physical activity, and maintenance of healthy body weight.

Avoiding weight gain during the adult years can reduce the risk of many cancers. For those who are already overweight or obese, the first goal is to avoid additional weight gain, followed by weight loss using a comprehensive diet and exercise method.
