OBJECTIVE: To investigate the association between hairdresser exposures and hormone-related conditions. METHODS: Using data from 50 800 eligible Sister Study participants (enrolled 2003-2009, aged 35-74 years), we estimated ORs and 95% CIs…

Uterine fibroids and endometriosis may be associated with an increased risk of ovarian cancer. Less is known about the role of hysterectomy in these associations. We estimated the independent and joint associations of hysterectomy, fibroids…

BACKGROUND: Fibroids and endometriosis are sex hormone-mediated and exhibit cancer-like behavior. Breast cancer may be more common in women who have had these conditions, but the literature is conflicting and does not always address factors…
