I would recommend seeing an Ear Nose & Throat doctor (otolaryngologist) - one that treats oral cancer patients. Is there a major cancer center near you? Can your oral surgeon recommend an ENT?

Dysplasia is a pre-cancer - it could change to cancer at some point, but it may never. I've have 4 surgeries on my tongue (same location each time) and the last 2 were done as your oral surgeon suggested. This procedure is also know as "frozen sections" where the pathologist will examine samples until they get clean margins. They also use a blue dye during the procedure that aids them in identifying abnormal cells.

There is a lot of great information on the main pages of the OCF website, and it has a search function.

Wishing you the best!
