Which type of skin cancer is the most common form diagnosed?

Basal cell carcinoma is recognized as the most common type of skin cancer diagnosed. This type arises from the basal cells located in the lower part of the epidermis. It typically develops in areas frequently exposed to the sun, such as the face and neck. Basal cell carcinoma is often characterized by its slow growth and a lower likelihood of metastasizing compared to other forms of skin cancer, making it the most prevalent.

While melanoma is more aggressive and can be deadly, it is less common in terms of overall cases. Squamous cell carcinoma, though it also ranks high in prevalence, is not as widespread as basal cell carcinoma. Merkel cell carcinoma is a rare and aggressive form of skin cancer. Thus, the statistics and clinical observations confirm that basal cell carcinoma constitutes the majority of skin cancer cases diagnosed each year.
