Which type of skin cancer is most commonly associated with sun exposure?

The most commonly associated type of skin cancer with sun exposure includes basal cell carcinoma and squamous cell carcinoma, which are both forms of non-melanoma skin cancer. While melanoma, which is a more aggressive form of skin cancer, is also influenced by ultraviolet radiation exposure, the other two types are more prevalent and directly linked to cumulative sun exposure over time.

Basal cell carcinoma arises from the basal cells of the epidermis and is often caused by prolonged exposure to sunlight, making it the most common skin cancer type linked to UV radiation. Similarly, squamous cell carcinoma originates from squamous cells and is also primarily associated with sun exposure. Consequently, all three types of skin cancer are indeed related to sun exposure; however, in terms of prevalence, basal cell carcinoma is the most commonly diagnosed.

Therefore, recognizing that all the mentioned types of skin cancers have associations with sun exposure supports the choice that they all fall under this category.
