Growths & Spots
Moles
Moles (nevi) are clusters of pigment cells that are usually harmless but should be checked if they change, bleed or look irregular. Board-certified dermatologists examine moles with dermoscopy and remove them by laser or excision, sending suspicious ones for biopsy.
Overview
In Korea, mole removal by laser is popular and quick. But laser destroys tissue without a sample, so a specialist must first rule out melanoma or other skin cancers.

Frequently asked questions
Is laser mole removal safe?
For clearly benign moles, yes; suspicious moles should be excised and tested.
Will a mole come back?
Deep moles can recur after laser and may need more sessions.
Can acral moles be cancer?
Melanoma on palms and soles is relatively more common in Asians, so changes there need prompt checks.

In Korea, only about 1 in 10 clinics that treat skin is run by a dermatology specialist (피부과 전문의). Specialists complete a four-year dermatology residency and a national exam.
