What should you know about Mohs surgery on the lip?

A dermatologist numbs the area, removes the visible lesion with a thin margin, and examines that layer under a microscope. If cancer cells remain at an edge, another targeted layer is removed and checked. This process can limit removal of healthy lip tissue, which matters for movement, speech, eating, and appearance. Mohs surgery may be used for basal cell carcinoma or squamous cell carcinoma when tissue preservation and clear margins are priorities.

The wound may be closed directly, allowed to heal gradually, or repaired with a flap or graft. The repair choice depends on the wound's size, depth, and position on the lip.

Tell the surgical team about medicines, supplements, allergies, bleeding problems, and previous reactions to local anaesthetic. Arrange a calm schedule for the procedure and follow the clinic's instructions about washing, dressing changes, food, and medicines. Keep the wound protected, avoid picking at crusts, and limit stretching of the lip while it heals. Swelling and tenderness can make talking or eating awkward at first; soft foods and small bites may be more comfortable if your clinician agrees.

Contact the surgical team promptly if firm pressure does not control bleeding, pain is worsening rather than settling, or the wound becomes increasingly red, warm, swollen, or draining. Seek urgent help for trouble breathing, rapidly spreading swelling, faintness, or swelling that interferes with swallowing. A planned review lets the team check healing and discuss scar care once the wound has closed.

Ask which type of skin cancer is being treated, how the lip wound is likely to be repaired, what eating and speaking restrictions to expect, and which symptoms should trigger a same-day call. You can also ask how follow-up will assess the scar and whether another specialist will join the repair.
