Hi, my partner was diagnosed with cancer in his tongue in December 2017. He has had two operations so far. The first one was a neck dissection on one side and lymph nodes removed and part of his tongue was removed.(the lymph nodes were clear) They then discovered in the margin some percancerous cells which had not been detected by any scans and so had a second operation to his tongue. The cancer or pre cancer cells had developed tentacles. He now needs a third one. He is a folk singer and has been told that he should forget about singing in the future. He will probably have to have radiotherapy. My question is, should he be changing his diet... He likes cakes and is doing alot of comfort eating after he has moved off soups once the swelling soreness dies down. He is likely to have radiotherapy. Are there any tips that would help.
