People often think there's little they can do to prevent cancer. But nothing could be further from the truth. In fact, up to two thirds of all cancer cases could be prevented if people acted on everything known about cancer prevention. Committing to a healthier lifestyle will not guarantee you a cancer-free life, but it will reduce your risk. Here are eight steps to start you on your way:

1. Make healthy food choices
2. Keep physically active
3. Stay tobacco free
4. Maintain a healthy weight
5. Protect yourself from the sun, especially between 10 a.m. and 4 p.m.
6. Follow screening guidelines
