Epithelial ovarian cancer subtypes attributable to smoking in the Norwegian Women and Cancer Study, 2012
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-01-14)
Among European women, ovarian cancer is the fifth most common cancer. Smoking is an established risk factor for mucinous tumors. We estimated the impact of smoking in Norwegian women using population attributable fractions (PAFs) of epithelial ovarian cancer (EOC), by invasiveness and by histological subtypes in the Norwegian Women and Cancer Study with an average of 13.2 years of follow-up. ...
Coffee consumption and the risk of cancer in the Norwegian Women and Cancer (NOWAC) study
