Risk Factors for Leukemia
A risk factor is something that raises a person's chances of getting a disease or health problem. A person can have leukemia with or without the risks below. The more risks a person has, the greater the chances are.
Leukemia is most common in adults aged 60 years and older. However, acute lymphoblastic leukemia happens most often in children under 8 years old. Males have a slightly higher risk than females.
Things that raise the risk of most types of leukemia are:
Smoking lets harmful chemicals into the body. Current or past smoking is strongly linked to acute myeloid leukemias and chronic myeloid leukemia. The risk is higher with the number of cigarettes smoked and years as a smoker.
