I have oral lichen planus.i read a lot about the cancer risk of that. rote, overall 1-2% and sometimes 0.2% for year.what is the real lifetime risk?

Numbers!: Numbers are numbers, so one has to talk with his primary care doctor or specialist to see what the numbers really mean. A 1-2% risk means... Well, it means 1-2% of the people will get it (one can think of that as a lifetime risk). That means if a person is one of the lucky 98%, he has nothing to worry about (but of course, one can't know for sure that he will be lucky).

See doctor: The best person to talk to a out your concerns is an oral medicine specialist, oral surgeon, or the doctor who is treating you. They can discuss the treatment and the risk of cancer.
