Basal cell carcinoma is most commonly located on the eyelid where?

Explanation:
Basal cell carcinoma on the eyelid most often involves the lower lid. The skin of the lower lid is thin and directly exposed to sun, and cumulative ultraviolet damage in this area drives the development of BCC. While the medial and lateral canthi can be involved, they are less commonly the primary site than the lower lid, and the upper lid, though affected, is seen less frequently than the lower lid due to relatively less sun exposure and protective overlay from the brow.
