Funny, I had a wart like growth on the back of my hand, doc bi-opsied it last week and just called me to let me know it was squamous, surgery scheduled in a couple weeks.
When I was a kid many moons ago, I had a big a$$ wart on my hand and a plantars wart on the heel of my foot, which hurted like hell.
The doctor electrically burned both of them, the plantars wart went away, the hand wart came back with a vengence.
