What is cancer?

Cancer occurs when cells in one part of the body, such as the colon, grow abnormally or out of control. The cancerous cells sometimes spread to other parts of the body, such as the liver. Cancer is the second leading cause of death in the United States.

How is cancer linked to overweight?

Gaining weight as an adult increases the risk for several cancers, even if the weight gain doesn’t result in overweight or obesity. It isn’t known exactly how being overweight increases cancer risk. Fat cells may release hormones that affect cell growth, leading to cancer. Also, eating or physical activity habits that may lead to being overweight may also contribute to cancer risk.

How can weight loss help?

Avoiding weight gain may prevent a rise in cancer risk. Healthy eating and physical activity habits may lower cancer risk. Weight loss may also lower your risk, although studies have been inconclusive.
