Has anyone dealt with this? It is a benign, wart-like cyst or tumor. I have one on my lower lip--came up suddenly with no previous trauma. It has been removed twice by a dermatologist and still has come back. Very annoying, unsightly, and painful. Some literature suggests that hormonal changes in the body can cause them, and as I am entering menopause I wonder if it is related. Going to see an ENT next.
