What to expect from tumour removal surgery for basal cell carcinoma

The clinician cleans and numbs the area, then removes the lesion and a margin of nearby skin. The wound may be closed with stitches, left to heal under dressings, or repaired with a graft or flap, depending on its size and location. Removed tissue is examined to check the diagnosis and whether the edges are clear. The procedure may be performed under local anaesthetic, with the setting and method chosen for the site and surgical plan.

Keep the dressing in place for the time given by your surgical team and wash your hands before touching the wound. Follow instructions for cleaning, ointment, and dressing changes. Avoid rubbing, soaking, heavy exertion, or stretching the area until advised. Mild tenderness, swelling, bruising, or a small amount of oozing can occur. Attend the wound check and stitch-removal appointment, and keep the pathology follow-up so the next step is clear.

Contact the surgical team for bleeding that does not settle with firm continuous pressure, increasing redness, warmth, swelling, pus, worsening pain, or fever. Seek urgent care for severe bleeding, faintness, or trouble breathing. A wound that opens, becomes increasingly painful, or changes colour also needs prompt assessment. Continue skin checks as advised because a history of basal cell carcinoma can require ongoing surveillance.

Ask how much tissue may be removed, how the wound will be closed, when pathology results are expected, and how the scar should be protected. Clarify dressing changes, activity limits, stitch removal, and the date of follow-up.
