Carcinogens Carcinogens are chemicals that cause cancer by causing mutations. Cancer may result if the mutations produce some of the characteristics described above. Generally, chemicals that produce mutations are more likely to cause cancer than those that do not produce mutations. The likelihood that any particular chemical will cause cancer can be determined by observing the rate at which it causes mutations in bacteria. This is the basis of the Ames test. Prevention of Cancer Behavior patterns contribute to approximately 40% of all cancers. Diet plays role in 35% of all cancer cases. The environment, workplace pollutants and natural causes play a role in the rest. 60% of cancer deaths can be prevented by not smoking and with diet, exercise, and screening. Smoking Smoking is responsible for 30% of all cancer deaths and 87% of all lung cancer cases. It causes 90% of lung cancer cases in men and 79% of lung cancer cases in women.
