Skin biopsy when melanoma is suspected

A dermatologist may inspect a changing or unusual pigmented spot with magnification before recommending a biopsy. When melanoma is a concern, removing the entire visible lesion with a narrow margin is often considered when practical, though the method depends on the lesion’s size and location. The laboratory report can describe melanoma cells and features that help determine whether more tissue needs removal. A biopsy cannot be interpreted from the wound’s appearance alone; the pathology report is central.

Tell the clinician about medicines that affect bleeding, allergies, prior reactions to local anaesthetic, and previous unusual scars. Keep the dressing and wound care exactly as instructed, and avoid picking or soaking the area until advised. Record the lesion’s location and keep your follow-up appointment so the result is explained clearly. If melanoma is found, ask about margin clearance, examination of nearby skin, and whether another specialist is needed.

Get in touch with the clinic if the site develops spreading redness, increasing heat, swelling, pus, or pain. Seek urgent attention for bleeding that does not settle with firm pressure or for fever with rapid wound deterioration. Do not delay assessment of a spot that is changing in size, colour, border, or sensation, or that repeatedly bleeds.

Ask whether the whole lesion should be removed, how the result will be communicated, what the pathology terms mean, whether further excision is needed, and how nearby or new moles will be monitored.
