Basal cell carcinomas (BCCs) are slow-growing, locally invasive, malignant epidermal skin tumours which are thought to arise from hair follicles. The tumour infiltrates local tissues through the slow irregular growth of subclinical finger-like outgrowths, and morbidity results from local tissue invasion and destruction, especially on areas of chronic sun exposure, such as the face, head and neck .
