Sex hormones and the risk of keratinocyte cancers among women in the United States: A population-based case-control study.

ABSTRACT: Men are at a higher risk of developing both squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) than women, but there is emerging evidence that women may be experiencing greater increases in the incidence rates of these malignancies than men. One possible explanation is the expanding use of sex steroids among women, although only a few studies have examined this hypothesis. As part of a population-based, case-control study of women in New Hampshire, USA, we sought to evaluate the risk of SCC, BCC, and early-onset BCC in relation to exogenous and endogenous sex hormones. We found that oral contraceptive (OC) use was associated with an increased risk of SCC (OR = 1.4, 95% CI = 1.1-1.8) and BCC (OR = 1.4, 95% CI = 1.0-1.8), particularly high estrogen dose (>50 mg) OC use.
