Is it possible to prevent cancer?

In some cases: In high-risk patients, some cancers can be prevented with medications (example- breast cancer by taking tamoxifen), lifestyle changes (example- oral cancer by quitting tobacco chews), workplace precautions (example- avoiding asbestos exposure to prevent mesothelioma).

Yes: Many causes of cancer are not genetic and the risk greatly decreased through lifestyle. Don't smoke. Exercise. Eat a healthy diet. Protect yourself from the sun. Avoid carcinogens such as asbestos. Don't drink excessively. Get regular screening tests as recommended by your doctor.
