I had leukoplakia on my lateral tongue for three years, don't know if I had dysplasia. When it first popped up I had it biopsied and it was negative for cancer. After consulting my dentist and an oral surgeon I ended up with an ENT who recommending monitoring and said only 1% turn into cancer. Well after 3 years I developed a sore spot and had my dr biopsy the spot. It was SCC cancer stage 1. I can't tell you what to do, but monitoring, rather than subject yourself to what may be unnecessary surgery, may be the way to go. Also, I agree with having regular surgery rather than laser so margins can be examined. Does dyplasia present make it more likely for cancer to develop? Keep up the doctor visits and if anything changes, however minor, get in to your dr.
