I have a small (I'd say ant sized) mole on my left upper arm. It's too small to really get a good look at. My family has no history of skin cancer, but plenty (bordering on tons) of irritating/embarrassing but benign skin conditions ranging from eczema to atypical moles and weird birth marks. Should I be worried? I was struck with facing my own mortality a few months ago when I nearly drowned, and now I'm paranoid I might have skin cancer despite my only "symptom" being the previously mentioned small mole. I know I've had it for years as well.
Doctorfag here. You're probably young (under 40) and chances of having skin cancer this age are pretty low.
However, any mole can evolve into cancer! I think you'll feel better ir you take it off. Any dermathologist can do it, and they also do a microscopical analyze to see if it's cancerous and shit.
Sorry for bad english.
Dark is bad, light is good. Different colors is bad, solid is good. Hair growth is good. Like the other guy said, a dermatologist or ever a family medicine practitioner can remove it or at least tell you it's fine.
