Hello, I have had a mole on my bck for as long as I coulf remember. A few years I had it looked at by a dermatologist and they said it was fine. NowI just noticed it has a sore on the middle and and a spot. I am very worried. Thoughts appreciated.
You probably have absolutely nothing to worry about, but I would get it checked out anyway.
As long as the color is solid throughout the mole it's probably normal. A melanoma mole will have shades of the same color - like brown or black, or splotches of different colors such as white, red, gray, black or blue. It also develops a ragged crust which I see you don't have. Keep an eye on it though for any change or it gets larger. But I think you're fine.
As it is a few years since a dermatologist looked at it I would get it checked out. It is probably nothing but you seem to have a skin that is prone to moles/freckles so any change needs to be checked. Hope you use plenty of high factor sun cream.
