For years I have had a small mark just right of my mouth on my cheek. It's not a mole or freckle, it actually looks exactly like a pock mark but I know it's not. It's been there so long I can't remember and hasn't caused me any bother. A while ago I noticed there was a long tube like lump under and to the side of it and the last few days I feel like the indent is getting worse.
All I can think of is skin cancer but I can't see anything similar to this when looking at the different forms of skins cancers.
