I am scheduled for my 2nd scan since treatment ended on May 5th. In the the last couple of weeks maybe not that long I have noticed a hard white area on the inside of my jaw. If you could draw a line straight through it would be almost exactly where the tumor was on my lip. It is white as was the tumor and seems to be growing by the day. I have a call into to Doctor to see if he wants to do anything different since I don't do well with PET Scans, the premedication is a problem, I was to have an ultrasound. Can anyone tell me if a recurrence would grow this fast I mean almost overnight? I know wishful thinking.
