What to expect from surgical excision for an atypical mole

The clinician marks the mole and the intended margin, cleans the skin, and numbs the area with local anaesthetic. The mole is removed as a specimen, sometimes with a small amount of surrounding skin, and sent for microscopic assessment. The wound may be closed with stitches, allowed to heal in a different way, or managed with a repair suited to its location and size. The procedure can leave a scar, whose appearance changes as it matures. The pathology result helps determine whether further removal or surveillance is appropriate; an atypical appearance alone does not establish cancer.

Follow the written dressing instructions and keep the area clean as directed. Avoid stretching, heavy friction, or activities that pull on the wound until the clinician says they are suitable. Do not pick a scab or remove stitches yourself. Take only recommended pain relief, and mention medicines that affect bleeding before the procedure. Attend the planned wound check and pathology appointment, even if the site looks settled. Once healed, protect the scar from strong sun and continue checking the rest of your skin for changing moles.

Contact the clinic if bleeding does not stop with steady pressure, the wound edges separate, or increasing redness, warmth, swelling, pus, or pain develops. Fever or feeling unwell may signal infection and needs prompt advice. Seek urgent help for heavy bleeding or a rapidly expanding swelling. Arrange review if the scar becomes persistently painful or if pigment or a new changing spot appears near the excision site.

Ask how much skin is likely to be removed, where the scar will sit, how it will be closed, when stitches come out, and when to expect the pathology result. Ask whether the result changes your skin-check plan and which warning signs should prompt a same-day call.
