Basal cells line the deepest layer of epidermis. The growths are malignant tumors that arise in this layer of skin. BCCs occur most frequently on sun-exposed regions of the body. Although this skin cancer rarely spreads to other organs of the body (i.e., metastasizes), it can cause destruction of surrounding tissue. 5-10 % of BCCs can be resistant to treatment or be locally aggressive, which damages the skin around them and sometimes invades bone and cartilage
