A nurse friend told me they are having a ton of success with immunotherapy for melanoma.

Not to freak everyone out but I did want to mention that something you should check for is under your toes. Yes you can get it there and it doesn't look like a mole, it looks like a bruise. A couple of years back I had to have my nail ripped off (wasn't that painful and shockingly grew back fast) and a biopsy done because a great nurse noticed it. Alas, turned out to be a bruise (because my shoes were too tight).
