Can cancer be prevented?

Some types of cancer may be preventable. For example, smoking cigarettes, cigars or pipes or using smokeless tobacco have been shown to cause cancer. To reduce your risk, don’t start; and if you already smoke, stop. To lower your risk of skin cancer, use sunscreen, wear a hat and shirt or just stay out of the sun when possible. Plus, eat a healthy diet with plenty of fresh fruits, vegetables and whole grains to help cut the risk of other cancers. Ask your physician how you can develop an anti-cancer lifestyle.
