A member asked:
3 days ago, my 3 mm-wide canker sore in the mouth closed up. however, i can still see a white line on the surface of my skin where it closed and the area is still red since then. does this count as nonhealing sore that can be a sign of cancer?
A doctor has provided 1 answer
Cancer: Cancerous lesions will not "close up" and appear to be healing. A non healing sore will remain the same or enlarge in size. Unless you have predisposing factors (like using chewing tobacco or smoking), it was probably just an ulceration. But to ease your mind, maybe your dentist should take a look.
