Hi, your description suggests you are diagnosed with Non Hodgkin Lymphoma, Stage ? (scans of the neck, chest,abdomen,pelvis and bone marrow tests, blood tests required to stage). Exact treatment options will be based on the disease stage. Most probable options are chemotherapy and/or radiation to the biggest swelling region. Bye.

Dear sir, From the reports shared by you, you are suffering from a type of blood cancer that can be treated well. I suggest you to contact a medical oncologist or hematologist for starting urgent treatment.  Apart from chemotherapy you would also benefit by starting a targeted treatment called Retuximab.
