I have a flesh colored bump on the edge of upper lip for over a year it doesn't hurt nor has it changed dentist said it was fine i'm starting to doubt?

Bump: In general, a flesh colored bump that hasn't changed in a year is harmless. Obviously, it's hard to evaluate without a picture, but cancer doesn't act like that. Hope this helps.

Lip bump: It is impossible to determine what this bump is without seeing it. Since you are concerned see an oral surgeon or a dermatologist for an evaluation.

Oral Surgeon: If in doubt about this bump have an evaluation by an oral surgeon. They are the experts in this area and will either be able to put your mind at ease, or treat the area if needed.

See the Oral Surgeon: Bottom line is you are concerned about it and should see the Surgeon to have your concerns adequately addressed. These types of presentations are most often nothing to worry about from a health standpoint, but bothersome. May be a traumatic fibroma from pulling / sucking that area with your teeth. Get the diagnosis and discuss your options. Good Luck.

See your dentist: Some conditions like bump on the edge of upper lip may require further assessment and your dentist may schedule a follow-up appointment or refer you to a specialist to determine a diagnosis. See your dentist for evaluation.
