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

Squamous cell carcinoma can appear as a rough or scaly patch, a firm growth, or an open sore that crusts, bleeds, and fails to settle. It may be tender, particularly when rubbed, and often occurs on sun-exposed skin, including the face, ears, scalp, hands, and lower legs.

This means the condition often presents with the symptom; it does not mean that every non-healing sore is squamous cell carcinoma. Irritation, infection, ulcers, and other growths may produce a similar appearance and require different care.

Book a dermatology review when a sore persists, repeatedly crusts, or changes in size, texture, or colour. A clinician may examine nearby skin and suggest a biopsy when needed. Keep the site clean and covered if it catches on clothing, and avoid applying harsh products or removing the scab.

Before the appointment, note its location, onset, symptoms, and any previous treatment. Tell the clinician about substantial sun exposure, immune suppression, or an earlier skin cancer if relevant to you.

Seek prompt assessment for repeated bleeding, increasing pain, pus, spreading redness, rapid growth, or a sore on the lip, ear, eyelid, or genitals. Urgent help is warranted for bleeding that will not stop with steady pressure.

Ask whether the sore needs a biopsy, what treatment options fit its site and depth, and how the surrounding skin should be protected. Ask what follow-up is needed after treatment and which new changes should be checked.
