Re: My mole fell off on its own- why?
The main rule I know about moles is that the healthy ones don't/shouldn't change in color, size or in any other ways. That being said, please don't think I am trying to scare you. But, to be on the safe side, you should make a visit to your dermatologist. You actually should be in the habit of seeing your derm once a year for a quick whole body skin exam. There is nothing to it. If there are any suspicious moles, your doc will remove it and biopsy it. I sort of look at the annual visit with a derm as as necessary as the annual OB-GYN visit.
I hope I didn't scare you but, fear can be the best motivator and you really should go get it checked out. Better safe than sorry!
