Looks like our treatment was about the same, I handed the chemo doctor the lab report from the Biopsy again.... one sample was to be tested for HPV I haven't heard anything.... but then again, why can't they just test me? I see him tomorrow, last Chemo... I'll ask. I'm 51 my cancer is BOT Stage 4 too.... I do keep swallowing... most the time nothing or crappy flem UGH. Sometimes a sip of water.... all I can drink of water is small sips. I'm wondering how long the mucasitis lasts.... is that what gets worse? ewwwwwwwwwwwwwwwwww I guess doctor said mine isn't too bad although it feels like it, no ulerations no bleeding... I do see blood in the spit once a while, just a little bit.
