Levonorgestrel-releasing intrauterine system use is associated with a decreased risk of ovarian and endometrial cancer, without increased risk of breast cancer. Results from the NOWAC Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-02)
<p><i>Objective</i>: Women with ovarian cancer have poor survival rates, which have proven difficult to improve; therefore primary prevention is important. The levonorgestrel-releasing intrauterine system (LNG-IUS) prevents endometrial cancer, and recent studies suggested that it may also prevent ovarian cancer, but with a concurrent increased risk of breast cancer. We compared adjusted risks of ...
Lifetime number of years of menstruation as a risk index for postmenopausal endometrial cancer in the Norwegian Women and Cancer Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-21)
<p><i>Introduction</i>: Lifetime number of years of menstruation (LNYM) reflects a woman's cumulative exposure to endogenous estrogen and can be used as a measure of the combined effect of reproductive factors related to endometrial cancer (EC) risk.</p> <p><i>Material and methods</i>: We aimed to study the association between LNYM and EC risk among postmenopausal women and calculate the population ...
Milk and risk of colorectal, colon and rectal cancer in the Norwegian Women and Cancer (NOWAC) Cohort Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-17)
According to World Cancer Research Fund International/American Institute for Cancer Research, it is ‘probable’ that dairy products decrease the risk of colorectal cancer (CRC). However, meta-analyses restricted to women have not shown associations between milk intake and risk of CRC. The aim of this study was to examine the association between milk intake and risk of CRC, colon cancer and rectal ...
Physical activity patterns and the risk of colorectal cancer in the Norwegian Women and Cancer study: A population-based prospective study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-04)
<p><I>Introduction</I>: Colorectal cancer (CRC) remains the second most common cancer in women worldwide. Physical activity (PA) has been associated with reduced risk of CRC; however, this has been demonstrated more consistently in men, while results of studies in women have been largely equivocal. We aimed to further examine the relationship between PA patterns and the risk of CRC in women, using ...
Progestin-only and combined oral contraceptives and receptor-defined premenopausal breast cancer risk: The Norwegian Women and Cancer Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-19)
Receptor-defined subtypes of breast cancer represent distinct cancer types and have differences in risk factors. Whether the two main hormonal forms of oral contraceptives (OCs); i.e. progestin-only (POC) and combined oral contraceptives (COC), are differentially associated with these subtypes are not well known. The aim of our study was to assess the effect of POC and COC use on hormone receptor-defined ...
