In popular literature, hepatitis C is often mentioned as one of the causes of lymphoma, i.e.:
Non-Hodgkin lymphoma - Wikipedia - Hepatitis C virus: associated with splenic marginal zone lymphoma, lymphoplasmacytic lymphoma and diffuse large B-cell lymphoma.
Hepatitis B does not seem to be cited very often as a cause of lymphoma, but is nevertheless mentioned as a probable cause in some academic or research papers, or at least the authors seem to indicate that there is a positive correlation between hepatitis B and some kind of lymphomas, i.e.:
Previous epidemiological studies have shown that HBV-infected patients (hepatitis B surface antigen positive) have a 2 to 3-fold higher risk of developing NHL than noninfected patients.
Any word on that from our experts? I myself was diagnosed with CLL; the diagnosis changed a few years later to SMZL.
