My Dad was diagnosed with stage 3 tonsil cancer which had spread to two lymph nodes. The tumour on his tonsils was 5cm. He had 30 rounds of radiotherapy and 2 rounds of chemotherapy and yesterday went for a check up with oncology. They scanned and said that the lump is still there and “not normal” at this stage of treatment so they’ve referred him back to ENT. I am trying to stay positive but struggling to understand what’s happening and why they can’t just remove the tonsils? Please can someone offer some insight?
