Cancer is one of the major killers of Americans today. Each year, more than 500,000 Americans die of cancer, with lung cancer, prostate or breast cancer, and colorectal cancer claiming the most victims.Despite the numerous genetic and environmental causes of cancer and its effect on so many Americans’ lives, there are some things you can do to limit your risk of cancer and to reduce its impact if you have cancer.Regular cancer screenings, proper nutritional habits and regular exercise have all been shown to be beneficial methods for fighting cancer.The American Cancer Society reports that more than half of all new cancer cases occur in areas of the body where screenings can be conducted. They estimate that if all Americans underwent regular screenings the survival rates for these cancers could be as high as 95 percent.Proper nutrition is also important in cancer prevention. The National Center for Health Statistics report that 33 percent of all cancers are caused by poor nutrition.Exercise is another key component in the fight against cancer.
