Red spot on my arm.
I noticed a red spot on my arm about two inches about my elbow. Out of curiosity I wanted to find out what some of the signs are that should have me tell a doctor. Looking at it, I noticed it was about 10 mm in length, not circular or oval but was oddly shaped. Now it has not changed size, shape, or color nor has it begun to bleed, itch, or become inflamed. I was wondering what the general consensus here would be in regards to if it could be Melanoma. Either way I'm seriously considering getting it looked at.
