Given my European heritage and natural predisposition for moles, and where we live (with more sunshine than the sunshine coast!), I am a little concerned. I still haven't taken DS to the gp about his cheek, but he will be going next week. My new concern is Mack. He has, what looks like a pimple, on his cheek, in almost exactly the same place as DS' mole. His mole started off the same way. Can you tell if a spot is going to develop into a mole? Is there anything you can do to prevent it? Thanks, I feel dumb asking though.
