24 Ways Top Doctors Prevent Cancer

Cut Back on Sugar

"The average American consumes 185 pounds of the sweet stuff in a year, or five times the recommended amount. Too much sugar can act like a fertilizer for cancer cells, encouraging them to grow and multiply. I always opt for seltzer or unsweetened tea flavored with lemon instead of sweetened beverages."—Mark Hyman, M.D., author of The UltraSimple Diet.

Spice Things Up

"Cooking meat over high temps creates carcinogenic compounds called heterocyclic amines, or HCA. I marinate meat and add herbs before grilling. Our studies show that doing this can slash levels of HCA by 40 percent."—J. Scott Smith, Ph.D., chair, Kansas State University's Food Graduate Program.

Pamper Yourself

"Research shows there's an undeniable link between stressed mental and emotional states and your susceptibility to disease, including cancer. Taking time out to do something just for you can reduce anxiety and give you a sense of control over your life. I try to book a massage once a month."—Susan Silberstein, Ph.D., CEO, beatcancer.org.

Add Tumeric

"An antioxidant and anti-inflammatory, this yellow spice attacks the core pathways that allow cancer cells to develop."—David Servan-Schreiber, M.D., Ph.D., author of Anticancer: A New Way of Life.

Fit in Fitness

"Getting sweaty for at least 30 minutes a day can reduce your risk of developing colon, breast, and endometrial cancers by 20 to 30 percent. Each morning I go for a run, or play tennis."—Jeffrey Meyerhardt, M.D., assistant professor of medicine, Dana-Farber Cancer Institute.

Be Phone Smart

"Cell phones emit radiation, which may up your odds of developing a brain tumor. Although the research is controversial, I take that risk seriously—and recommend that everyone use a headset."—John Tew, M.D., clinical director, University of Cincinnati Neuroscience Institute.

Clean Green

"We tested more than 20 cleaning products and found they released up to seven carcinogens not listed on the label. Among the worst offenders were air fresheners and bathroom cleaners. I make my own cleaners from baking soda and vinegar."—Rebecca Sutton, Ph.D., senior scientist, Environmental Working Group.

Pass on Plastic

I never microwave anything in a plastic container. Pthalates and bisphenol A (BPA), which can leach into food when plastics are heated, mimics hormones and may increase the risk of certain cancers, including breast and ovarian. Use a microwave-safe ceramic or glass bowl instead."—Jeffrey Morrison, M.D., founder, The Morrison Center.

Eat Berries

"All types of this fruit contain a phytochemical ellagic acid, which has been shown to slow tumor growth and help eliminate carcinogenic substances from the body."—David Servan-Schreiber, M.D., Ph.D., author of Anticancer: A New Way of Life.
