Had my biopsy done a week ago and find out tomorrow with another visit to the OS. Dentist found a white mark on the right side of my tongue about 5 weeks ago and recommended I get it checked. CHewed tobacco for 2 years but quit three years ago.......dumb move I know but it was an Army thing when I was deployed. Anyway.....nervouse and can't sleep. The OC says is does not look like any start of oral cancer he has ever seen in his 25 years bot the only way to be sure was the biopsy. I certainly hope this comes back negative.
