I have tonsil cancer and lymphnode involvement on both sides of my neck. I had 2 surgeries and 2 rounds of radiation in 8 months. I did not get a PEG tube. I have horrible mouth ulcers, chronic thrush and I can't eat fruit because of the acid and most other foods I eat based on texture. Most of my taste is gone. Meat tastes somewhat like metal. I have a loss of appetite and alot of weight loss but I chose not to get a PEG tube because I felt like I lost control over another aspect of my life. I just powered through it. I have 3 treatments left of my radiation. I did not have chemo. I think it is a choice and as long as you can eat something and not loose a dangerous amount of weight I would not do it but I tend to be a maryter when comes to pain.
