Do I have skin cancer?

I have a small mole on my arm and it is a greenish color. I've had it for as long as I can remember. Could it be skin cancer? Maybe a vein under it or something?

Have your MD take a look at the mole. If it has always been like this, it is likely fine. If you suddenly notice any change in a mole or a new mole appears just be cautious and go see your MD. It's never to cautious to be on top of these things.
If you think it's the same shape and color as always just bring it up at your next appointment with the MD. If you are worried call. Source(s): RN

i hope.... lol jk. go to the doctor. and ask them. im guessing its a vein.
of course you don't have skin cancer .don't worry.just go visit an doctor.
get tested and ask for a bioptsie.
Well at first when I read 'greenish color' I was a bit alarmed and thought it might be something... but when you said you've had it as long as you can remember... that is highly unlikely to be cancerous... Generally cancer happens when the cells mutate and grow out of control, which causes visual changes to a mole.... if its never changed or grown noticeably larger, then i wouldnt worry. And as far as the green color.... i have no idea... do you have olive colored skin by any chance?
Just a harmless mole, has it grown in size ? if no forget about it, enjoy life. Do not get depressed unnecessarily. Good luck.
