Which type of skin cancer is the most common?

Basal cell carcinoma is recognized as the most common type of skin cancer. This form of cancer arises from the basal cells, which are found in the lower part of the epidermis, the outer layer of the skin. Basal cell carcinoma often develops in areas of the skin that are frequently exposed to sunlight, such as the face, ears, and neck.

The reason it is the most common skin cancer is due to the prevalence of sun exposure, which is a significant risk factor. Unlike melanoma, which is more aggressive and can spread to other parts of the body, basal cell carcinoma typically grows slowly and rarely metastasizes. Despite being the most common, it is often highly treatable, particularly when detected early.
