i just had to jump in on this because i too have those bony growths in the roof of my mouth. six months ago a sore developed at the back side of one near my throat. it got larger and became bright red and was very sore when i would eat. last thursday i had a biopsy. he cut about a fourth of the bony struture away. he thought it was nothing because cancer usually does not show up in the roof of the mouth. the biopsy came back on the following tuesday. it was a precancer lesion. he got it out in time. now i am struggling to give up the smoking that is being blamed. i'm not sure which is worse. just make sure to have it checked.
