1. Should I really be worried about this?
No. If a
moleBirthmarks - pigmented
Gestational trophoblastic disease
Hydatidiform mole
Pth has moderate atypia, most pathologists recommend that the whole mole be removed, just to be sure it couldn't turn into something someday (even though we don;t really know if it ever would.) If the mole has been completely removed already, there's nothing more to do or think about. Your doctor can tell you whether that's the case. If it isn't, the doctor can take a little bit more tissue off to make sure the mole is gone.
2. What are the chances of this turning into melanoma?
Once it's off, no chance.
3. Am I predisposed to this type of problem and melanoma now that I have had one?
Not unless you have lots of other funny moles. Having one moderately atypical mole doesn't increase your risk of melanoma very much, or at all. In any case, all you need to do is get yourself checked regularly, so the dermatologist can look at all your moles.
Take care.
