Thanks, Cheryl! It does make me nervous, in fact, my surgeon had a similar pt whose sentinel was neg and popped up w a pos node 6 months later. But it is rare, so I'm hopeful that w an HPV pos, small T1 lesion, neg scans, in combo w the neg sentinel, maybe I'm truly cancer-free! The sentinel node was actually a grouping of 3, and they were all neg. also my tongue path showed no peri neural or peri vascular invasion. Do I sound like I'm trying to convince myself? Lol. If I pop positive later, I'll clearly need SND and radiation, but was willing to take the chance and our Tumor Board agreed. I really debated, but am at peace w it now. And the skin allograft was essentially a biological dressing - just to assist w even healing. Wasn't big enough for true grafting. It's getting better each day; just really hard to eat and talk. But I'm just happy to have it out of me. Thank u for the advice. I will certainly keep everyone updated as to my progress. This board is so helpful. Who knew there were so many of us w this awful cancer!
