Hello all. My mother was recently diagnosed with having a tumor in her throat. The biopsy results are not back yet, but I overheard the nurse mention stage 3 tongue cancer when she was making appointments for my mother with other doctors. My question is this...what, exactly, is stage 3 tongue cancer and how do they know she has that when the biopsy hasn't come back yet? And how treatable is this?! The dr. said that they would try chemo and xray therapy first and if it didn't respond they would have to remove her tongue and voicebox. Somebody, please talk to me about this! My mother is scared out of her wits and so am I.
