Which type of skin cancer is known for its connection to chronic sun exposure?

Basal cell carcinoma is the most common type of skin cancer and is closely associated with chronic sun exposure. This connection arises because the UV radiation from the sun can cause cumulative DNA damage in the skin cells. Basal cells, which reside in the lower epidermis, are particularly susceptible to such damage. The characteristic growth of basal cell carcinoma often manifests as a pearly or waxy nodular lesion or a flat, scaly patch, which may bleed or crust over.

Chronic sun exposure leads to a higher risk of mutations that trigger the abnormal growth of these cells, leading to the development of skin cancer over time. This forms the basis for recognizing basal cell carcinoma as a direct consequence of prolonged UV exposure, making it a prominent concern in dermatology, particularly for individuals with fair skin or those who spend significant time outdoors without proper sun protection.
