Using any type of tobacco puts you on a collision course with cancer. Smoking has been linked to various types of cancer — including cancer of the lung, bladder, cervix and kidney — and chewing tobacco has been linked to cancer of the oral cavity and pancreas. Even if you don’t use tobacco, exposure to secondhand smoke may increase your risk of lung cancer.

Avoiding tobacco — or deciding to stop using it — is one of the most important health decisions you can make. It’s also an important part of cancer prevention. If you need help quitting tobacco, ask your doctor about stop-smoking products and other strategies for quitting.
