How common is skin sore that does not heal in squamous cell skin cancer?

Squamous cell skin cancer may appear as a rough or scaly patch, a raised growth, or an open sore that crusts, bleeds, and fails to close. It can occur on sun-exposed skin and may become tender as it changes. Similar findings can arise from wounds, inflammation, or infection, so the symptom does not identify the cause by itself. A clinician may use examination and a biopsy to confirm what the spot is.

Arrange a prompt medical review for a sore that persists or repeatedly reopens. Track its position and note changes in tenderness, bleeding, crusting, firmness, or surface area. Keep it clean, avoid scratching or picking, and do not use another person's treatment. Cover it if friction causes bleeding, and protect exposed skin from sunlight while waiting for assessment.

Seek prompt care if the sore grows, becomes increasingly painful, bleeds with little contact, or develops a thick crust or raised border. Use urgent services for bleeding that remains uncontrolled, fever with spreading redness, or severe pain. A changing sore should be examined even if it has not caused symptoms before.

Ask whether the lesion needs a biopsy, what the examination suggests, which treatment options suit its location, and how to care for the area after treatment. Ask whether nearby lymph nodes or additional checks need attention based on the findings.
