I did not have tonsil cancer, but another form of head and neck SCC. I have done complementary immunotherapy treatments for 12 years which I started right after the radiation with targeted chemotherapy was complete. Through the Quantum Immunotherapy Clinic in Freeport, Bahamas, I met other patients with your disease. The best results were seen with those who followed traditional treatments and then followed up with their complementary therapies. They are looking into reduced radiation treatments currently at larger cancer centers and that might be something for you to look into. I have used both traditional and complementary treatments for my cancer which had a 30% 5 year survival rate, and I am still in the game 12 years later. I am also a medical professional so I believe in what we know about western medicine. Perhaps look into a naturopathic physician for advice and guidance. The sooner you get on top of your cancer, the better your outcome. There are newer approved immunotherapy drugs that are being used with less side effects than some chemotherapies. I used one for 2 years recently when I had another metastasis and it completely cleared my kidney and lymph node mets ( so far, knock on wood). Find a head and neck oncologist that you trust even if you have to travel to see them. We drive 10 hours for my oncologist at MAyo Rochester. She is amazing! Good luck.
