When to Worry About Skin Lumps with Basal Cell Carcinoma

Basal cell carcinoma can appear as a shiny or pearly bump, a firm growth, or a sore that repeatedly crusts and heals incompletely. Some lesions have visible small blood vessels, darker pigment, or a rolled edge. They often develop on sun-exposed skin such as the face, ears, scalp, neck, or hands. Many skin lumps are benign, so appearance alone cannot confirm the cause; diagnosis may require a clinician’s examination and sometimes a biopsy.

Book a skin assessment for a new lump or one that changes in size, surface, colour, or sensation. Take a clear photograph with a familiar object for scale and note when you first noticed it, but do not use photographs to delay an examination. Protect the area from sun and avoid picking, shaving over, or repeatedly irritating it.

Seek prompt medical review if the lump bleeds with little contact, forms a sore that does not heal, repeatedly crusts, becomes tender, or grows or changes. Ask for urgent advice if bleeding will not stop with steady pressure, or if there is rapidly increasing redness, swelling, or severe pain. A timely examination helps determine the next step.

Ask what features make the lump concerning, whether a biopsy is appropriate, and how to protect the area while waiting. Tell the clinician about previous skin cancers, significant sun exposure, immune suppression, and any change in bleeding, crusting, or healing.
