Thanks for the replies everyone. Because my husband's mother doesn't have insurance, we're still waiting for those biopsy results from the ENT. It's a full week already. The one good thing that my MIL's diagnosis did do, was cause our Aunt Ro to go back to her doctors for a full check up. (Remember she had foolishly sworn off doctors because of her depression?) Aunt Ro has some type of nodules on the newly reconstructed floor of her mouth, so she's having a biopsy done on July 11th. Two in one family is just overload and very hard to deal with.
The only thing I can think of besides their family's strong predisposition to cancer in general, is that fact that neither took very good care of their eating habits, health habits etc. and both live on the east end of Long Island and get their water supply from Brookhaven, the place where they found toxic chemicals in the ground water a few years ago. I suspect that the "modern" world we live in has everything to do with it.
I'll keep everyone posted,
Lisa S.D.
