Stage 4 Tonsil cancer. Lymph node involvement both sides. No surgery. 7 weeks of cisplatin and radiation. Discovered with lump on right side just underneath jaw. Now a year out of treatment. After treatment the "lump" was gone. Then "grew back." Oncologist says it is just "scar tissue." From the radiation? Never had surgery. CT scan and then Pet scan a month or so after treatment completed show tumor almost nonexistent. But then this "growth" of "scar tissue." You can see the swelling on the right side of neck below the jaw line. But oncologist swears just scar tissue. However, he will not do any CT or Pet scans, ever, unless he sees "something." Insurance will not pay otherwise apparently. Now this "lump" or "scar tissue" will move side to side if pressed.

Any thoughts? No symptoms, no pain, no difficulty swallowing (or no more so than expected).
