What are basal cell and squamous cell cancer?
Basal cell carcinoma is a cancer that begins in the deep basal cell layer of the epidermis (the outer layer of the skin). It is six to eight times more common than malignant melanoma. It is often located in the face and on the neck. Basal cell carcinoma is not one of the most dangerous cancers, but it must still be treated to avoid it spreading. ‘Rodent ulcer’ is an alternative term sometimes applied to basal cell carcinoma. Squamous cell carcinoma begins in a different layer of the epidermis. It is not as common as basal cell carcinoma and is typically found in places exposed to sunlight, like the face or neck. Like basal cell carcinoma, squamous cell carcinoma is not among the most dangerous cancers, but it can become dangerous if it is not treated in time.
