Being infected with certain viruses or bacteria may increase the risk of developing cancer:
Ionizing radiation is high frequency radiation with enough energy to damage the DNA in cells, which can cause cancer. Common sources of ionizing radiation are from rays that enter the Earth's atmosphere from outer space, radioactive fallout, radon gas and X-rays.
Radioactive fallout can come from accidents at nuclear power plants or from the production, testing, or use of atomic weapons. People exposed to fallout may have an increased risk of cancer, especially leukemia and cancers of the thyroid, breast, lung, and stomach.Radon is a radioactive gas that you cannot see, smell, or taste. It forms in soil and rocks. People who work in mines may be exposed to radon. In some parts of the country, radon is found in houses. People exposed to radon are at increased risk of lung cancer. Medical procedures are a common source of radiation. Low dose radiation comes from X-rays, and risk of cancer is very low. High dose radiation is used for cancer treatments. For both, the benefits nearly always outweigh the risk.
People who have a poor diet, do not have enough physical activity,
or are overweight may be at increased risk of several types of cancer.
Diets high in fat may cause an increased risk of colon, uterus and
prostate cancers. Lack of physical activity and being overweight are
risk factors for breast, colon, esophagus, kidney and uterus cancers.
To reduce these risks, eat a nutritious diet and exercise to
maintain a healthy weight. Your diet should include foods that are high
in protein, fiber, vitamins and minerals. Low-fat meats, nuts, whole
grain breads, fruits and vegetables help to build immunity to cancers.
Limit foods high in fat such as butter, whole milk and fried foods.
