Cancer runs in my family. Am I destined to get it, too?

Not necessarily. The top three things you can do to tip the odds in your favor are to maintain a waistline that's generally less than half your height in inches, eat low on the food chain, and not be a toxic dump—avoid exposure to cigarette smoke and asbestos, things like that. You can't control your genes, but they aren't as significant as how you affect them with risk factors you can control, such as smoking and obesity.
