Squamous Cell Carcinoma
Squamous cell carcinoma (SCC) is caused by chronic exposure to ultraviolet radiation (UVB). They appear as thick, red scaly lesions that may bleed easily and occur in sun-exposed areas. SCC is an invasive disease and is therefore always treated surgically.
- Fair skin, blue eyes and blond or red hair
- Actinic keratoses or previous SCC
- Outdoor occupation or recreation
- Clinical features confirmed by skin biopsy or following excision.
- Patients with high-risk SCC may also undergo staging investigations to determine whether it has spread to lymph nodes or elsewhere.
- Surgical excision
- Shave, curettage and cautery for low-risk tumours
- Mohs micrographic surgery
Risks for developing more SCCs
- Patients who already have actinic keratoses or previous SCC
- Patients with multipleSCCs may be prescribed an oral retinoid
- Most SCCs are cured by treatment, but may recur
- 50% develop a second SCC within 5 years of the first
