Basal cell carcinomas (BCCs) are keratinocyte tumours that resemble the basal layer of the epidermis, and are the most commonly diagnosed human cancer among persons of European ancestry.

Basal cell carcinomas, the most common form of skin cancer, occur in chronically sun-exposed areas such as the face. Locally advanced tumors in particular can be difficult to treat surgically.
