When is mole removal recommended for atypical mole?

An atypical mole, also called a dysplastic naevus, may look different from a person's other moles in shape, colour or border. Its appearance alone cannot establish whether it is cancer. A dermatologist may compare it with earlier photographs, examine it with a dermatoscope and decide whether monitoring or removal is appropriate.

Removal allows the tissue to be examined in a laboratory. The method depends on the mole's size, depth, site and the clinical question. Some atypical moles remain stable and can be followed with planned checks, while a changing or difficult-to-assess lesion may need removal.

Arrange a skin assessment if a mole changes in size, shape or colour, develops several shades, bleeds, crusts, itches persistently or becomes noticeably different from your other moles. Do not cut, burn or repeatedly irritate it yourself. Bring previous photographs and mention personal or family skin-cancer history. Read about [Mole Removal](/treatments/surgical-dermatology/mole-removal/) before deciding.

Seek prompt medical review for a rapidly changing mole, spontaneous bleeding, a new persistent sore, marked asymmetry or a lesion that stands out from the rest of your moles. These signs do not prove cancer, but delay can make assessment harder. After removal, contact the clinic for persistent bleeding, increasing redness, pus, fever, spreading pain or wound opening.

Ask why monitoring or removal is advised, whether a dermatoscopic photograph is useful, what procedure will be used, whether the whole mole will be removed, how the wound will be closed and when the laboratory result will be reviewed. Discuss scar care and follow-up for other moles.
