RICHMOND, Va. - By improving your eating habits and increasing your physical activity, you can lower your chances of getting cancer. The American Cancer Society (ACS) has updated its guidelines on cancer prevention. The focus is on weight control, through nutrition and staying active.

Denise Kolba with the ACS says those who are obese literally change their body chemistry, which raises the risk of cancer.

"We know that people who are overweight and obese tend to have higher levels of insulin and estrogen circulating in their blood. And research has shown us that these hormones are related to cell growth, and so therefore are really thought to influence our cancer risk."

Some of the new guidelines are lifestyle choices, such as maintaining a lifelong healthy weight, being physically active, limiting alcohol consumption and consuming a diet rich in plant-based foods.

Kolba says the new guidelines also emphasize proper portion sizes.

"Halving the portion size is the most important thing you can do, but also it's important to decrease your amount of processed and red meat. Eat at least two-and-a-half cups of fruits and vegetables a day. Choose whole grains in preference to refined-grain products."

Accoding to the ACS, excessive weight is a factor in 14 percent to 20 percent of U.S. cancer deaths, and those who follow the new recommendations for diet and exercise will also reduce their risk of cardiovascular disease. Kolba adds no matter what your age or weight, you can still lower your cancer risk.

An overview of the new guidelines is available at www.cancer.org.
