Hormone replacement therapy use and plasma levels of sex hormones in the Norwegian Women and Cancer Postgenome Cohort : a cross-sectional analysis
Waaseth, Marit; Bakken, Kjersti; Dumeaux, Vanessa; Olsen, Karina Standahl; Rylander, Charlotta; Figenschaug, Yngve; Lund, Eiliv (Journal article; Tidsskriftartikkel; Peer reviewed, 2008-02-14)Background: Hormone replacement therapy use (HRT) is associated with increased breast cancer risk. Our primary objective was to explore hormone levels in plasma according to HRT use, body mass index (BMI) and menopausal status. A secondary objective was to validate self-reported questionnaire information on menstruation and HRT use in the Norwegian Women and Cancer postgenome cohort (NOWAC). Methods: ... -
Overdiagnosis of breast cancer in the Norwegian Breast Cancer Screening Program estimated by the Norwegian Women and Cancer cohort study
Lund, Eiliv; Mode, Nicolle; Waaseth, Marit; Thalabard, Jean-Christophe (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)Background: There is increasing ambiguity towards national mammographic screening programs due to varying publicized estimates of overdiagnosis, i.e., breast cancer that would not have been diagnosed in the women’s lifetime outside screening. This analysis compares the cumulative incidence of breast cancer in screened and unscreened women in Norway from the start of the fully implemented Norwegian ... -
Plasma Fatty Acid Ratios Affect Blood Gene Expression Profiles - A Cross-Sectional Study of the Norwegian Women and Cancer Post-Genome Cohort
Olsen, Karina Standahl; Fenton, Christopher Graham; Frøyland, Livar; Waaseth, Marit; Paulssen, Ruth H; Lund, Eiliv (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)High blood concentrations of n-6 fatty acids (FAs) relative to n-3 FAs may lead to a “physiological switch” towards permanent low-grade inflammation, potentially influencing the onset of cardiovascular and inflammatory diseases, as well as cancer. To explore the potential effects of FA ratios prior to disease onset, we measured blood gene expression profiles and plasma FA ratios (linoleic ... -
