The most common type of eyelid cancer is:

• A. Squamous Cell Carcinoma
• B. Adenocarcinoma
• C. Basal Cell Carcinoma
• D. Melanoma

Answer: (C)

Basal cell carcinoma shows up most frequently on the eyelid because it arises from the basal cells in the epidermis and hair follicles, and sun exposure is a major risk factor. The eyelid skin is thin and often sun-exposed, so this cancer tends to develop there more than other types. It typically grows slowly and, while it rarely spreads to distant sites, it can cause significant local tissue destruction if not treated. Clinically, it often appears as a pearly or translucent lesion with rolled borders and visible blood vessels. The standard approach is surgical removal with clear margins, and a high cure rate is common when caught early. In contrast, squamous cell carcinoma is less common but more aggressive and carries a higher risk of metastasis, while melanoma, though serious, is less common on the eyelid but can be deadly if it spreads. Adenocarcinoma of the eyelid glands is rare.
