Answer

Historically, men are affected twice as often as women. The higher incidence in men is probably due to increased recreational and occupational exposure to the sun, although these differences are becoming less significant with changes in lifestyle. The current male-to-female ratio is approximately 2.1:1.

For tumors involving the periocular skin, Cook et al reported the incidence of BCC to be equal in men and women. [45] In addition, this investigative team found that the age-adjusted incidence rates for all malignant tumors of the eyelid in men and women, respectively, were 19.6 cases and 13.3 cases per 100,000 population per year. The age-adjusted incidence rates for BCC of the eyelid for men and women, respectively, were 16.9 and 12.4 cases per 100,000 population per year.
