1. Don't smoke or use any tobacco products. Smoking causes a host of cancers, including cancers of the lung, esophagus, mouth, throat, stomach and pancreas, according to the National Cancer Institute. It's also the leading cause of premature, preventable death in the United States. If you've tried to quit before, don't give up — eventually something will work, McTiernan said.
2. Get screened for cancer regularly. Screening tests can detect cancers of the colon, breast, prostate, cervix and skin (ask your doctor how often to get them and at what age you should start). Even if you don't have any symptoms yet, finding cancer early greatly increases your chances of treatment and even cure. Screening tests can include physical exams, blood tests, imaging and X-rays and genetic tests.
3. Limit your alcohol consumption. This means no more than two drinks per day for men and one drink per day for women. Oral cancer is six times more common in alcohol users than in people who don't drink, according to the American Cancer Society. And you can't "save up" all your drinks for a week and then binge on Friday night with your weekly "allotment," McTiernan said.
4. Protect your skin from the sun. Its ultraviolet rays damage the skin's DNA and can cause genetic mutations that lead to skin cancer, according to the Skin Cancer Foundation. Use sunscreen every time you go outdoors (preferably one with an SPF of 30 or higher that protects against both UVA and UVB rays). Keep covered with a broad hat and sunglasses.
5. Be physically active. Research shows active people have a lower risk of developing colon and breast cancers than people who don't exercise, according to the Centers for Disease Control and Prevention. You don't need to be a super-athlete to get the benefits of exercise. Activities such as brisk walking, biking, dancing or any exercise that raises your heart rate and makes you sweat is beneficial.
