What are the risk factors for lymphoma?
Though doctors do not yet know what causes lymphoma, one possible risk factor is a weak immune system. Reasons why your immune system can become weak include:
- Using immunosuppressants after an organ transplant.
- Having an autoimmune disease.
- Being exposed to infections like HIV, Helicobacter pylori, hepatitis C or the human T-cell leukemia/lymphotropic virus.
