I first noticed a raised white line on my lower lip about a year ago. It starts on the inside and goes to the outside. Sometimes it hurts and gets raw feeling around it. I do not remember ever doing anything that cut my lip, especially bad enough to scar it. Is there any form of cancer that looks like a scar? It is a white line that is raised slightly. As far as I can really tell it has not gotten any bigger, but it worries me. My lower lip also almost constantly feels raw and tender. Would using too much lip balm cause this? I constantly use carmex or blistex because it always feels so raw.
