We do not know exactly why people get cancer. What researchers do know is that doing certain things, like exercising regularly and eating a healthy diet—and not doing others, like smoking or sunbathing—can reduce our cancer risk. This article discusses how lifestyle habits can prevent cancer and some of the cancer tests you should know about, if you're age 50 or older.
