Cancer Causes and Risk Factors
- NCI Cancer Causes and Risk Factors Webpage
Doctors often cannot explain why one person develops cancer and another does not. But research shows that certain risk factors increase the chance that a person will develop cancer. Many of these risk factors can be avoided. Others, such as family history, cannot be avoided. People can help protect themselves by staying away from known risk factors whenever possible.
- NCI Tobacco and Cancer Webpage
Tobacco is one of the strongest cancer-causing agents. Tobacco use is associated with a number of different cancers, including lung cancer, as well as with chronic lung diseases and cardiovascular diseases.
