How long does surgical excision take to work for basal cell carcinoma?

During excision, the surgeon removes the basal cell carcinoma with a planned margin of surrounding skin and closes the wound. The operation treats the lesion at that visit, but the final result is not judged by appearance alone. A laboratory examines the specimen and checks whether the edges are clear of tumour cells. If the edges are involved, the dermatologist or surgeon may discuss additional removal or another treatment. Even when the result is reassuring, the scar remains in a healing phase and can change in colour, firmness, and sensitivity.

The expected course depends on the tumour's size and site, the closure method, and your general healing. Lesions near the eyes, nose, ears, or lips may need particularly careful follow-up.

Follow the written wound-care plan, including dressing changes, washing, ointment, and stitch removal. Avoid picking the scab or placing tension on the closure, and ask when exercise or swimming can resume. Keep every appointment so the pathology result is explained and the wound is checked. Once healed, protect the scar and remaining skin from excessive ultraviolet exposure. Check your skin regularly for new or changing lesions, and report any concern rather than treating it at home.

Call the surgical team for persistent bleeding, wound separation, increasing swelling, spreading redness, pus, fever, or worsening pain. Arrange prompt assessment for a sore that does not heal, repeated bleeding or crusting, a pearly or scar-like new spot, or a change at the treated site. These signs need examination and should not be assumed to be ordinary scar healing.

Ask when the pathology result will be reviewed, whether the margins are clear, how long the wound should be protected, and whether the site needs additional treatment. Ask for a personal skin-check plan and guidance on symptoms that should bring your appointment forward.
