Basal cell carcinomas are the most common form of skin cancer overall, and also the most common epithelial tumor of the eyelid.

It's not only burning that puts you at risk. Cumulative exposure (repeated sunbathing without burning) is linked to basal cell and squamous cell carcinomas.

Specifically, little is known about the proliferation and differentiation of basal cells, a multipotent stem cell population of the pseudostratified airway epithelium.
