Squamous cell carcinoma itch: what to know

A squamous cell carcinoma is a cancer of squamous cells in the outer layers of skin. It may look like a scaly patch, a firm bump, a wart-like growth, or a sore that crusts or bleeds. Itch can come from surface inflammation, dryness, crusting, or pressure in the surrounding tissue. Eczema, infection, an insect bite, and other non-cancerous conditions can also itch, so a clinician must examine the area and may take a biopsy.

Arrange a skin examination if an itchy spot persists, changes, repeatedly crusts, bleeds, becomes painful, or fails to heal. Do not pick the crust or apply strong steroid, acid, or wart treatments without advice. Note when the itch began, whether the lesion is growing, and any history of sun exposure or previous skin cancer. If confirmed, treatment may involve removal such as Surgical Excision, Mohs Surgery, or another form of Skin Cancer Surgery, depending on the site and findings.

Seek prompt medical assessment for a sore that keeps returning, a rapidly enlarging growth, bleeding with minor contact, marked tenderness, numbness, or a lesion near the eye, ear, nose, lip, or another functionally sensitive area. Get urgent help if bleeding will not stop with firm gentle pressure or if there are signs of spreading infection such as worsening warmth, swelling, and fever.

Ask whether the appearance needs a biopsy, what else could explain the itch, how much tissue may need removal, and how the wound will be cared for afterward. Clarify how you will monitor the treated site and nearby skin for new or changing lesions.
