So, I posted the following thread:
http://www.wdfnews.com/forums.aspx?g=posts&t=10826
In which I asked WDF?, "I have a small mole on my left buttocks that looks different from the last time I noticed it. Should I be concerned? "
To which he responded, "Yes. You have cancer. "
Well, I had a physical last week and the doctor told me to see a dermatologist right away. So, I made an appointment with the first Dr. who would see me who was in my insurance plan. Here's what his exam room looks like:

He looked everywhere.
He found lots of good stuff to write down.
He ran his fingers through my hair.
He used his magnifying thingie to get up close and personal.
He grunted and hmmfed a lot.
Then when he was done, he said he would like to biopsy one of them because it was an irregular shape, it was big, and I couldn't do a self-exam on the area too easily. (My backside, remember?)
It was the mole I asked WDF? about:

Notice there's a hair growing out of it. I didn't know this and I find it kinda gross.
But, he wants it off, so, it's gonna come off at another visit so he can screw the insurance company back for not paying him very much per patient visit.
So, yeah, I had reason to be concerned. And WDF? was right.

You should be more like Cantrip.
