Lifestyle factors typically can play a large role in warding off health problems and many studies speak to the benefits of specific foods and exercises. But, what about lesser known ways to stay healthy? Here are 10 ways to reduce your cancer risk—some of which may surprise you. Many studies have found a link between red meat consumption and risk of certain types of cancer. And, meat that is charred, burned or grilled over high temperatures may be especially dangerous, as it can cause heterocyclic amines to form. HCAs may cause genetic damage and increase risk of stomach and colorectal cancers. Women who regularly work night shifts may be at a higher risk of developing breast cancer--although most research says that it takes about 30 years of consistent night shift work to lead to increased risk of breast cancer. Researchers believe that long-term exposure to artificial lighting can suppress melatonin production, which may increase cancer risk. Evidence does not conclude that using birth control pills causes breast cancer, but research has found that women who use them may have a 10 to 30 percent higher risk of breast cancer than women who have never used them. Studies also show that women who stop taking the pill can reduce their risk of cancer over time. Speak with your doctor about the safety of oral contraceptives and safer alternatives. Instant coffee can contain acrylamide, a chemical compound shown to be linked to cancer in animal studies. The chemical has also been found to cause nerve damage, according to the Food and Drug Administration. Research on the effects of acrylamide is still preliminary, but it has been confirmed that ground, filtered coffee contains smaller amounts of the chemical than instant coffee. There's no question that there are health benefits to eating fish. But, for some people, eating too much fish may be a problem. Some research has found that males with high levels of omega-3 fatty acids in their blood may be at a greater risk of developing prostate cancer. Men should speak with their doctor about appropriate fish intake and whether omega-3 supplements are safe. Brown rice in particular has been found to contain higher levels of arsenic—a carcinogen—than other grains. Long-term health risks remain unclear, but experts recommend that you wash brown rice, white rice and other grains before cooking.
