Hi. I'm new. Started smoking when I was 12. First biopsy of leukplakia when I was 20 and 4 more times through my 20's and 30's. No one ever told me that they were precancerous. Dx when I was 41 SSC. free flap surg.,neck dissection and 35 rad. Just finished treatments in August. Feeling GREAT now. But definitley be your own advocate. If you don't feel satisfied keep pushing. I quit smoking when I was 32 by the way...
