Lymphoma is chemo thing, not radiation. Over several visits (she was coughing up blood, had large mass in lung, had been smoker since she was 12) doc mentions "lung cancer only responds to surgery"......and..."whatever YOU have, is inoperable". Next visit, he opines that "you're kind of hoping for a lymphoma". (Read between the lines) That was longest 3 weeks of my life waiting for biopsy, etc. Turns out it was lymphoma
