Skin Cancer Surgery: What to Expect

Skin cancer surgery removes the tumour and a margin of nearby skin, with the wound closed directly or reconstructed when needed.

The specimen is examined to check whether the edges are clear. Depending on the cancer's type, size and position, the wound may be stitched, left to heal gradually, or covered with a graft or flap. Basal Cell Carcinoma, Melanoma and Squamous Cell Carcinoma can each require different margins and follow-up.

Expect a dressing, tenderness and swelling around the wound at first. Keep the area clean and follow the surgeon's dressing instructions; avoid stretching or heavy activity if the site could pull apart. A review checks healing and explains the pathology result. Scar colour and firmness can change for months, while sun protection helps reduce contrast between the scar and surrounding skin.

The usual risks are bleeding, infection, wound separation, altered sensation and a noticeable scar. The cancer can also extend beyond what was visible, leaving involved edges and a need for further treatment. Risk depends on the tumour, body site, operation and your health, so your surgeon should explain the specific balance rather than promise a fixed outcome.

Surgery aims to remove the treated cancer completely, but no operation prevents a new skin cancer elsewhere or guarantees that a tumour will not return. The pathology report guides whether margins are clear and whether more treatment is needed. Scheduled skin checks and attention to changing lesions remain part of long-term care.

The diagnosis is usually confirmed with a biopsy before definitive surgery. Local anaesthetic is common for smaller lesions, while a larger or complex operation may need a different anaesthetic plan. Bring a list of medicines, allergies and previous problems with bleeding or wound healing.

A dermatologist or surgeon may recommend surgery for a biopsy-proven cancer, a lesion that is highly suspicious, or a tumour whose position, depth or growth pattern makes tissue removal appropriate. The plan considers the face, ears, hands and other sites where preserving function or appearance matters.

The team marks the site, cleans the skin and provides anaesthesia. The surgeon removes the planned tissue, labels it for laboratory examination, controls bleeding and closes or covers the wound. You receive dressing and warning-sign instructions before leaving, with follow-up arranged for wound review and results.

The first days focus on protecting the dressing and controlling discomfort. Stitches are removed or reviewed according to the body site and closure. Walking is often possible quickly, but strenuous exercise may wait until the wound is secure. Contact the clinic promptly for spreading redness, pus, fever, persistent bleeding or a wound that opens.

Tell the clinician about blood thinners, diabetes, immune conditions, smoking and medicines or supplements that affect healing. Do not stop prescribed treatment without instructions. Seek urgent help for heavy bleeding that does not settle with firm pressure, breathing difficulty or severe swelling.

Depending on the diagnosis, site and depth, options can include another form of local treatment, planned surveillance for selected lesions, or treatment directed by an oncology team. A skin biopsy may be the step that establishes what the lesion is before choosing among these routes.

Look for a dermatologist or surgeon who regularly treats skin cancers and can explain margin assessment, closure choices, pathology follow-up and scar care. Ask who will review the specimen, how to reach the team after surgery, and what changes should trigger an earlier appointment.
