Mole Removed, Now 2 Months Later Small Portion Grown Back?

The best way to remove moles is through excision with lasers being considered as another option. Shaving always allows the moles to come back.

When a shave biopsy is performed, the "roots" of the mole can be left behind, and this can cause re-pigmentation within the scar.  As long as the pathology revealed a benign growth the first time, it is unnecessary to re-biopsy it. 

A shave biopsy is usually the best way to go to have a mole removed and checked for cancer, especially one that is growing in that location. It typically leaves a minimal scar which sometimes will have a central area of hyperpigmentation. The mole will rarely regrow and the appearance with the central dark spot should not be objectionable. This is because the mole is actually "shaved off" at a level just below the surface of the skin. Since the biopsy results showed it to be benign, further treatment is not necessary.
