Hi. I am a 42 year old female with an avid love of the sun. I do wear sunscreen and I am very careful about exposure, but haven't always protected my lips. I have olive skin, but do burn occaisionally. Last week a brown spot appeared on my lower lip, right in the center, toward the inside of my mouth. It is flat, there are no cracks or dry areas, but my first thought is skin cancer, of course. It does not tingle or itch and there isn't any pain. Is there anyway to get rid of the spot? (I am also very vain about my looks. LOL)
