Well, a cold sore : Usually resolves within around 7 to 14 days, but a cancerous lesion will not likely come and go. See your dermatologist for any questionable lesion. Take care.

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?
