When to worry about a non-healing skin sore with basal cell carcinoma

Skin Sore That Does Not Heal is a very common presentation of Basal Cell Carcinoma. This skin cancer often develops in sun-exposed areas and may look like a sore that repeatedly crusts, bleeds, or partially heals before opening again. It can also appear as a shiny bump, a pink or reddish patch, or a firm area with a changing border.

A slow change does not make it harmless. Basal cell carcinoma can extend into nearby skin and tissue, so the clinician considers its size, depth, location, and whether it has returned after treatment. Other conditions can also cause an open sore; examination is needed to tell them apart.

Do not pick the crust or apply a new acid, steroid, antibiotic, or herbal product unless a clinician has advised it. Keep the area clean, protect it from rubbing, and use a simple dressing if it catches on clothing. Note bleeding, tenderness, discharge, growth, and the date of each change.

Bring previous biopsy or treatment details, the names of skin products, and a list of medicines that affect bleeding or healing. A clinician may use close inspection and may take a tissue sample before recommending treatment.

Book a prompt review for any sore that remains open, repeatedly bleeds, grows, becomes tender, or develops a raised, firm, or rolled edge. Contact the care team sooner if the sore is near the eye, nose, ear, lip, or another area where swelling or tissue damage could affect function.

Seek urgent help for bleeding that does not settle with steady pressure, rapidly spreading redness, increasing warmth or swelling, pus, fever, or severe pain. If basal cell carcinoma has already been treated, report a new or returning sore at the treatment site rather than waiting for the next routine check.

Ask whether the sore needs a biopsy, which treatment options fit its location and depth, and how the wound should be protected. Ask how often the treated area and the rest of your skin should be checked, and which changes should prompt an earlier visit.
