Non-Hodgkin’s Lymphoma Risk Factors
Doctors do not know what causes non-Hodgkin’s lymphoma. There are several factors that may increase risk. Keep in mind that many people who get the disease have none of the risk factors. And most people with the risk factors do not develop the disease.
Non-Hodgkin’s lymphoma is more common in men than in women, and the risk increases with age. Also, you may be at higher risk for non-Hodgkin’s lymphoma if any of these is true:
- Your immune system is weakened by an inherited disease, autoimmune disease, human immunodeficiency virus (HIV), or drugs given because you had an organ transplant.
- You have been infected with human T-lymphotropic virus type I (HTLV-1), Epstein-Barr virus (which causes mononucleosis), Helicobacter pylori (a bacterium that causes ulcers), or hepatitis C virus.
- You were exposed to certain chemicals, such as ingredients in pesticides, herbicides, solvents, or fertilizers.
