One point everyone else didn't mention but I'll hit. Carbo, and or cisplatin is ONLY effective for oral cancer in conjunction with radiation. Likely they won't reradiate if it is back (what you're feeling in term of a recurrence may just be healing or residual fall out from radiation.) I'd push for an MRI, the only reason I say this is because of the Erbitux/cisplatin/carbo - HPV conundrum. I do believe in clinical trials but in conjunction with standard treatment not in replacement of - too much risk where your life is concerned. So if it is a recurrence so soon after I think surgery is you option, unless as charm says theyre willing to do cyber knife etc.. Good luck. I hope very much this is just a scare.
