I would talk to your surgeon - or perhaps another surgeon (second opinion) . Firstly - normally tongue cancer (oral tongue - not base of tongue HPV +) should be treated with surgery first - as in - remove ALL the effected tissue first. When he presented with more cancer almost immediately following his initial surgery - that tells me 2 things - they didn't get it all the first time ( I'm going to quote an actual oncologist here. Recurrences especially those that are close together like that - mean they didn't get it all in the first place. ) Secondly normally tongue cancer (not HPV related base of tongue) but oral tongue can be aggressive, everything should be done at the outset to stop it in its tracks. Sometimes they'll send a person home after removing a T1tumor and say your okay, but with the extra nodes coming into play so shortly after, there should have immediately been a set up for chemo and radiation - and fast. Not a little bit of chemo, then rads. it's almost like your dr was trying to minimize the treatment from the outset (which could very much be related to the patient being reluctant - only you would know that). But now your saying, there's another mass in the tongue and more nodal involvement. The rest of the rads may take care of it as radiation is cumulative, but I would ask what the follow up treatment is if it isn't... And I would get a second opinion since your treatment so far hasn't really followed the standard. Cathi here had a tingue tumor and it was treated with 3 rounds of induction chemo and then radiation and chemo combined - shes faured very well, but they moved very quickly with her. By all means finish the radiation, but definitely get a second opinion, and some answers - Good luck... And take care.
