Risk Factors for Leukemia
A risk factor is something that increases your chances of developing cancer.
It is possible to develop leukemia with or without the risk factors listed below. However, the more risk factors you have, the greater your likelihood of developing leukemia. If you have a number of risk factors, ask your health care provider what you can do to reduce your risk.
Risk factors for leukemia include the following:
Environmental and Chemical Factors
People exposed to the chemical benzene, certain chemotherapy drugs, or radiation are more likely to develop leukemia than those who have not had similar exposure. Researchers are still investigating these associations. The exposures may trigger changes to the genes that later lead to cancer. However, the direct mechanisms of how these agents cause leukemia is not yet known.
Down syndrome is considered to be a risk factor for leukemia and newborns with this syndrome may have transient leukemia in the newborn period that resolves. These children are also 10 to 30 times more likely than average to develop leukemia in childhood, often by the age of 5.
Having a parent, sibling, or chid with chronic leukemia may increase your chance of developing the disease. However, leukemia is not considered an inherited disease.
Smokers over age 60 are twice as likely as nonsmokers to develop acute myeloid leukemia. About 20% of adult leukemias may be attributed to tobacco use. Cancer-causing chemicals in tobacco enter the blood stream and can increase the risk of malignancy.
Caucasians are more likely than African Americans to develop acute leukemia. The reason for this is unknown.
