Farland LV et al. – The current study showed an association between endometriosis and the risk of skin cancer, and the association was strongest for melanoma.

Methods

• 98,995 women with surgically-confirmed endometriosis and skin cancer were queried every 2–3 years via self-report.

Results

• 535 melanomas, 247 squamous-cell carcinomas, and 1712 basal-cell carcinomas were diagnosed during the study period.
• Endometriosis was associated with an increased overall risk of skin cancer (HR = 1.28).
• Endometriosis was associated with melanoma risk (HR = 1.64), but not with squamous cell carcinoma (HR = 1.21), or basal cell carcinoma (HR = 1.16).
