What should you know about life after melanoma in situ?

Melanoma in situ means abnormal melanoma cells are confined to the top layer of the skin. Treatment commonly removes the affected area with a margin of surrounding skin, and the pathology report guides whether the edges are clear. It is different from invasive Melanoma, which has grown deeper. Follow-up is still worthwhile because a person who has had one melanoma may develop another separate skin lesion. The original scar can remain firm, itchy, numb, or sensitive while it heals.

Attend the follow-up schedule provided by your dermatology or cancer team and keep a record of appointments and pathology results. Once the wound has healed, check your skin in good light, including the scalp, soles, nails, and areas that are difficult to see; a trusted person can help. Report a new spot or a mole that changes in size, shape, colour, or sensation. Use shade, clothing, and broad-spectrum sunscreen to reduce ultraviolet exposure, and avoid deliberate tanning. Ask before starting a new supplement or treatment marketed as cancer prevention.

Contact your care team promptly for a changing pigmented lesion, a sore that does not heal, bleeding, a growing lump near the scar, or enlarged lymph nodes. Urgent assessment is needed for severe wound redness, spreading warmth, pus, fever, or rapidly increasing pain. New neurological symptoms such as weakness, confusion, seizures, or a severe persistent headache need emergency attention, although they are not expected from melanoma in situ alone.

Ask when the next skin examination is due, whether the excision margins are clear, how to inspect the scar, and which family members should help with checks. Clarify whether you need additional surgery, a Sentinel Lymph Node Biopsy, or any treatment beyond local excision based on your pathology.
