Basal cell carcinoma arises from what type of tissues?

Basal cell carcinoma (BCC) arises from the basal cells located in the epidermis, the outermost layer of the skin. These basal cells are responsible for producing new skin cells as old ones shed off. BCC is primarily linked to prolonged sun exposure, leading to mutations in the DNA of these cells. As a result, the uncontrolled growth of these mutated basal cells forms tumors characteristic of BCC.
