Does squamous cell carcinoma cause sore that will not heal?

Squamous cell carcinoma can appear as a rough or scaly patch, a firm bump, or an open sore that crusts, bleeds, or returns after seeming to improve. It may occur on sun-exposed skin, but it can develop elsewhere. Most people with Squamous Cell Carcinoma notice sore that will not heal; this describes how the condition can present, not what any individual sore proves.

A sore may also result from injury, infection, poor circulation, inflammation, or another skin condition. Appearance alone cannot confirm the cause. A clinician may examine the area closely and, when needed, take a small sample for testing.

Arrange a dermatology assessment for a sore that persists, repeatedly crusts or bleeds, becomes tender, or changes in size, shape, or surface. Keep it clean, avoid picking the crust, and protect nearby skin from sun exposure. Photographing changes can help you describe its course.

Do not apply strong steroid, acid, or unregulated lightening products to an unexplained sore without advice. Learn more from [Squamous Cell Carcinoma](/conditions/squamous-cell-carcinoma/) and [Sore That Will Not Heal](/symptoms/non-healing-sore/).

Seek prompt care if bleeding will not stop with gentle pressure, pain is rapidly increasing, redness is spreading, or there is pus, fever, or a new swollen area nearby. An urgent assessment is also sensible for a sore near the eye, nose, mouth, or another area where swelling affects function.

Ask what features need checking, whether a biopsy is appropriate, how to dress the area safely, and what changes should prompt faster review while you wait.
