Re: Mole removed, but is coming back
I would agree with Oleander: get it checked out. Put it this way - would you rather give up some time now to get this checked, or not bother with it and have it possibly turn into melanoma? It's your choice, but understand the choice you're making.
As to your question, yes, it is possible for moles to grow back. Cancerous moles, non-cancerous moles. However, you, me, the doctor cannot always tell by merely looking at a re-grown mole whether it is cancerous, non-cancerous, or pre-cancerous. I've had moles that I just "knew" had to be cancerous removed, and there were not. And then the one I thought was not turned out to be melanoma.
It's your choice, it's your life. A little bit of inconvenience is definitely worth the effort.
