How effective is curettage and cautery for seborrheic keratosis?

Curettage lifts or scrapes away the raised surface, while cautery treats the base and controls bleeding. The method can suit a raised, well-defined growth, particularly when the aim is to remove a lesion that catches on clothing or causes irritation. It is not appropriate to assume every dark or rough growth is a seborrheic keratosis. A lesion that changes, bleeds without rubbing, or looks different from a person’s other growths may need examination before removal. The treated spot can crust, feel tender, and look lighter or darker as it heals.

Have the growth assessed before arranging removal, and tell the clinician about anticoagulants, skin conditions, allergies, and previous raised scars. After the procedure, keep the area clean and follow dressing instructions. Let the crust detach naturally, avoid friction and picking, and protect newly healed skin from strong sun. A removed seborrheic keratosis can be treated again if it regrows, but a new growth elsewhere is a separate lesion. See the Curettage And Cautery treatment guide for more information.

Contact the clinic for persistent bleeding, spreading redness, worsening pain, pus, or delayed wound closure. Request assessment if the lesion changes rapidly, becomes very dark, or returns with a different appearance. Those features should be reviewed rather than attributed automatically to a benign growth.

Ask whether the appearance is typical, whether a sample should be examined, what mark may remain, and how to care for the site. Ask when to return if the growth regrows or the colour change does not settle.
