Hello there, i was here a while back, almost 2 years. I had a buccal cavity biopsy on a slowly healing, recurring sore, left cheek. It turned out to be negative. For which i was so grateful. Well, now, for the last 9 months I have had a hard lump on my inside, lower lip with numbness, tingling, and swelling surrounding this hard lump. So...i have an appointment for a biopsy and ultra sound of my inner lower lip and chin on, November 30th. That was the first available appt here . I am on the waiting list for cancellations however, this is unnerving. I seem to keep having these whitish plaques, and now this hard lump.
