Does basal cell carcinoma cause a skin sore that does not heal?

Basal cell carcinoma may look like an open area that repeatedly crusts, bleeds, appears to improve, and then breaks down again. A clinician needs to examine the area because appearance alone cannot confirm the cause.

The affected area can be a pearly or shiny bump, a flat scaly patch, or a sore with a raised edge. It may bleed after minor contact or form a scab that keeps returning. Basal cell carcinoma often develops on skin with substantial sun exposure, including the face, ears, scalp, neck, and arms.

A non-healing sore can also follow irritation, infection, poor circulation, inflammation, or another skin condition. Its persistence is the reason to arrange assessment, not proof that it is cancer.

Book a medical appointment if the area does not settle, repeatedly reopens, grows, changes, or bleeds. Note when you first saw it and whether its size, colour, surface, or symptoms have changed. A clear photograph can help document change between appointments.

Avoid picking the scab or applying harsh chemicals. Protect the site from sun and friction. The clinician may inspect it closely and, when needed, take a small skin sample to identify the cause.

Seek prompt help if bleeding will not stop with firm pressure, the area becomes rapidly more painful or swollen, redness spreads, pus appears, or you develop fever. Arrange timely assessment for a sore near an eye, nose, lip, or ear, or for any lesion that is enlarging or repeatedly ulcerating.

Ask whether the lesion needs a biopsy, how the result will be communicated, which treatment choices fit its location and size, how to care for the site meanwhile, and what future skin checks and sun protection are appropriate.
