Has anyone here ever been diagnosed with a melanoma/skin cancer?

I have a mole on my leg and its freaking me out... it has a very irregular shaped edged... the thing is, I can remember it changing shape years ago when I was a teenager, and I never did anything about it.
Now I swear to god that I am so paranoid about it that I cant keep my mind off it and keep imagining that I can feel this 'tingly' feeling all around this spot in my leg, and I'm convinced the cancer is spreading...

I know this is a totally irrational vent, and I am going to go and get it checked out this week, but ARGH I am scared that it is going to be one! And the worst thing is if that you leave a melanoma undetected for too long, there is very little chance of curing it.

Anyway I guess I will soon know one way or another...8-[

Sorry guys just needed to vent that.... 8-[
