Which is the most common type of skin cancer?

Explanation:
Basal cell carcinoma is the most common skin cancer. It develops from the basal cells of the epidermis and is strongly linked to UV exposure, which over time damages skin cells. Because sun exposure affects a large portion of the population, basal cell carcinomas occur far more often than other skin cancers, especially non-melanoma types. They tend to grow slowly and, while they rarely spread to distant sites, they can invade surrounding tissue if not treated. By comparison, melanoma is less common but more likely to metastasize, squamous cell carcinoma is the next most common non-melanoma type and can be more aggressive than basal cell, and Merkel cell carcinoma is rare and highly aggressive.
