Selenium is well-known for its cancer-fighting properties. In a study of almost 1,000 men, researchers from the Journal of the National Cancer Institute found that when men with the lowest initial levels of selenium in their bodies received a daily supplement over a 4½-year period, they cut their prostate cancer risk by a remarkable 92 percent. However, it is possible to get too much of a good thing, so monitor your intake of selenium-containing supplements, Brazil nuts, tuna, meats and grains carefully.

Eat Sushi

Seaweed may not be your idea of a great snack, but it is high in fiber, calcium and iron, and dry, roasted seaweed sheets used in sushi provide the additional benefits of vitamins A and C. Sushi rolls are also high in protein - a typical spicy tuna roll has only 290 calories but packs 24 grams of protein. When scientists fed brown seaweed to mice inundated with UV rays, their incidence of skin tumors dropped 60 percent and existing tumors diminished by 43 percent. So don't skimp on the sushi!

Enjoy the Outdoors

Vitamin D causes early death of cancer cells. A study published in the American Journal of Clinical Nutrition reported that women who supplemented their diets with 1,000 international units of vitamin D every day had a 60 percent to 77 percent lower incidence of cancer over a four-year period than did women taking a placebo. Experts recommend supplementing your fun in the sun with 1,100 to 2,000 IU of vitamin D each day.

Breathe Clean Air

There's no question that secondhand smoke kills. A recent American Journal of Public Health study showed that nonsmokers working in smoky places had three times the amount of carcinogen in their urine than nonsmoking workers in smoke-free locations. What's worse, their levels of the carcinogen rose 6 percent for every hour worked. Nine states have banned smoking in all workplaces, bars and restaurants. The message is clear: Do whatever you can to avoid the cloud of smoke.

Break a Sweat

Even a small amount of exercise can offer major cancer-fighting benefits. In a study of 29,110 men published in the International Journal of Cancer, men who exercised just once a week had a 30 percent lower risk of metastatic prostate cancer than men who didn't work out at all. The better the frequency, duration and intensity of the exercise, the bigger the reduction in risk, according to the study.
