[/INST] Hi, dairy have gone through your question. I can understand your concern.  If you confirmly diagnosed for lymphoma then you should start treatment of that.  If you don't have confirmed diagnosis then you should go for biopsy and immunohistochemistry for confirmation.  Radiotherapy and chemotherapy is the treatment of choice for lymphoma depending on the type and stage. Consult your doctor and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health. </s>
