Pagan, the link above to removing that "pet" using apple cider vinegar is spot on. Make sure you use Bragg's Organic "With the Mother". My wife is all about organic stuff and knows about that particular type of vinegar very well. I'm guessing the pharma companies hate that stuff because it's really great in all sorts of situations. I've used it myself to remove a mole on my back (after seeing a dermatologist, having him remove it, and seeing it grow back again). Once it came back my wife interceded and permanently removed it using Bragg's as described in the article.

Another mole I had that was bugging me was essentially over my canine tooth on the right side. It was just off any whiskers but close enough that I accidentally sliced into it pretty often. Interestingly, after about 5 times getting sliced with a straight razor it just gave up and never returned. I guess you just never know how a mole will react.

So advice from a somewhat old guy - see your dermatologist, and after he does what he'll do (and if it grows back anyway), use the Braggs as described.
