Tobacco use is associated with the cause of death from cancer. A significant number of people die from cancer each year that is related to tobacco use.


Ionizing radiation such as radiation from outer space, radioactive fallout (accidents at nuclear power plants or production, testing or use of atomic weapons), radon gas (radioactive gas formed in soil and rocks), x-rays and the like can cause cell damage that leads to cancer.  People exposed to radioactive fallout are most vulnerable to the risk of cancer, especially leukemia and cancers of the thyroid, breast, lung, and stomach. People who work in mines may be exposed to random to increase the risk of lung cancer.

The various types of cancers associated with virus and bacteria include cervical cancer, liver cancer, leukemia, lymphoma, stomach cancer, etc.


Researches indicate that menopausal hormones may increase the risk of breast cancer, heart attack, stroke, or blood clots.

Poor diet, lack of physical activity, or being overweight:

Factors like poor diet, lack of enough physical activity or overweight increase the risks of cancer of colon, uterus, prostate, breast, esophagus and kidney.
