1. Eat a healthy diet
Although making healthy selections at the grocery store and at mealtime can't
guarantee cancer prevention, it might help reduce your risk. Consider these guidelines:
Eat plenty of fruits and vegetables. Base your diet on fruits, vegetables and other foods
from plant sources — such as whole grains and beans.
Avoid obesity. Eat lighter and leaner by choosing fewer high-calorie foods, including
refined sugars and fat from animal sources.
If you choose to drink alcohol, do so only in moderation. The risk of various types of
cancer — including cancer of the breast, colon, lung, kidney and liver — increases with the
amount of alcohol you drink and the length of time you've been drinking regularly.
Limit processed meats. A report from the International Agency for Research on Cancer,
the cancer agency of the World Health Organization, concluded that eating large amounts of
processed meat can slightly increase the risk of certain types of cancer.
2. Maintain a healthy weight and be physically active
Maintaining a healthy weight might lower the risk of various types of cancer, including
cancer of the breast, prostate, lung, colon and kidney.
Physical activity counts, too. In addition to helping you control your weight, physical
activity on its own might lower the risk of breast cancer and colon cancer.
Adults who participate in any amount of physical activity gain some health benefits. But
for substantial health benefits, strive to get at least 150 minutes a week of moderate
aerobic activity or 75 minutes a week of vigorous aerobic physical activity. You can also
do a combination of moderate and vigorous activity. As a general goal, include at least
30 minutes of physical activity in your daily routine — and if you can do more, even
3. Get regular medical care
Regular self-exams and screenings for various types of cancers — such as cancer of
the skin, colon, cervix and breast — can increase your chances of discovering cancer
early, when treatment is most likely to be successful. Ask your doctor about the best
cancer screening schedule for you.
