Medication risk: It is very hard to take medications when your care team is required by law to obtain informed consent. Certainly your physicians would not give you a medication which was likely to help your illness if it was more likely to cause lymphoma. With autoimmune disease in particular, untreated disease itself can increase the risk of lymphoma, and treating the inflammation can reduce risk. Good luck!
