What is the most common form of skin cancer?

Basal cell carcinoma is recognized as the most common form of skin cancer. This type arises from the basal cells, which are found in the epidermis, the outermost layer of skin. Basal cell carcinoma typically develops in areas of the skin that have been exposed to the sun, such as the face and neck.

Its prevalence can be attributed to various factors, including excessive sun exposure, fair skin, and a history of sunburns. Unlike melanoma, which can be more aggressive and can spread to other parts of the body, basal cell carcinoma tends to grow slowly and is less likely to metastasize, making it more common yet less lethal.

While squamous cell carcinoma is also a significant form of skin cancer, it occurs less frequently than basal cell carcinoma. Melanoma, although very serious and aggressive, is rarer compared to the other forms of skin cancer. Carcinoma in situ refers to a localized cancer that has not invaded surrounding tissues; it is not classified among the primary forms of skin cancer in terms of prevalence.

Thus, basal cell carcinoma stands out as the most common skin cancer diagnosed, underscoring the importance of sun safety practices and regular skin checks.
