How common is a non-healing sore in basal cell carcinoma?

Basal cell carcinoma may appear as a sore that crusts, bleeds with minor contact, improves briefly, and then breaks down again. It can also look like a shiny bump, a pink patch, or a scar-like area, especially on skin that receives regular sun exposure.

The condition-to-symptom direction matters: basal cell carcinoma commonly presents with a sore that does not heal. A persistent sore by itself does not identify the cause, since irritation, infection, injury, and inflammatory skin conditions can also delay healing.

Arrange a skin examination for any sore that keeps returning or fails to close. The clinician may inspect it with magnification and recommend a small biopsy if the appearance needs confirmation. Avoid picking the crust and protect the area from sun while waiting for review.

Note when the sore began, whether it bleeds, and whether its border or colour has changed. A clear history helps the clinician decide how urgently it should be assessed.

Seek prompt care if the area bleeds repeatedly, becomes increasingly painful, develops spreading redness or drainage, or changes quickly. Do not delay review for a sore near the eye, nose, ear, or another area where swelling or tissue damage could affect function.

Ask what features make the sore concerning, whether a biopsy is needed, and how the location affects treatment choices. You can also ask how to dress the area and what changes should lead you to return sooner.
