(HealthDay News) — Of course, you should quit smoking. But poor diet, being overweight and not getting enough exercise also are risk factors for developing cancer, the American Cancer Society says.

Being overweight or obese raises your risk of cancers of the breast, colon, esophagus, pancreas and kidney, the cancer society warns.

When it comes to food, the cancer society suggests eating smaller portions of high-calorie foods; eating fruits, veggies and legumes over other types of food; and avoiding unnecessary sugars and saturated fats.

Watching what you eat will help control your weight, as will getting enough exercise. The society cites guidelines recommending at least 150 minutes per week of moderate exercise, or 75 minutes per week of vigorous exercise.
