    • Polymorphisms in the estrogen receptor alpha gene (ESR1), daily cycling estrogen and mammographic density phenotypes 

      Fjeldheim, Frøydis Nyborg; Frydenberg, Hanne; Flote, Vidar Gordon; McTiernan, Anne; Furberg, Anne-Sofie; Ellison, Peter T.; Barrett, Emily S.; Wilsgaard, Tom; Jasienska, Grazyna; Ursin, Giske; Wist, Erik; Thune, Inger (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-10-07)
      Background: Single nucleotide polymorphisms (SNPs) involved in the estrogen pathway and SNPs in the estrogen receptor alpha gene (ESR1 6q25) have been linked to breast cancer development, and mammographic density is an established breast cancer risk factor. Whether there is an association between daily estradiol levels, SNPs in ESR1 and premenopausal mammographic density phenotypes is unknown. Methods: ...

    • Psychological effect of cervical cancer screening when changing primary screening method from cytology to high-risk human papilloma virus testing 

      Andreassen, Trude; Hansen, Bo Terning; Engesæter, Birgit Øvstebø; Hashim, Dana; Støer, Nathalie Charlotte; Trope, Ameli; Moen, Kåre; Ursin, Giske; Weiderpass, Elisabete (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-14)
      From 2015, Norway has implemented high‐risk human papilloma virus (hrHPV) testing in primary screening for cervical cancer. Women aged 34–69 years, living in four counties, have been pseudo‐randomly assigned (1:1 randomization) to either hrHPV testing every 5 years (followed by cytology if hrHPV is positive), or cytology testing every 3 years (followed by hrHPV testing if low‐grade cytology is ...

    • Timing of HPV16-E6 antibody seroconversion before OPSCC: Findings from the HPVC3 consortium

      <i>Background</i> - Human papillomavirus type 16 (HPV16)-E6 antibodies are detectable in peripheral blood before diagnosis in the majority of HPV16-driven oropharyngeal squamous cell carcinoma (OPSCC), but the timing of seroconversion is unknown.<p> <p><i>Patients and methods</i> - We formed the HPV Cancer Cohort Consortium which comprises nine population cohorts from Europe, North America and ...

    • Trajectories of body mass index in adulthood and risk of subtypes of postmenopausal breast cancer 

      Busund, Marit Katinka; Ursin, Giske; Lund, Eiliv; Wilsgaard, Tom; Rylander, Karin Charlotta Maria (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-28)
      Background - Body fatness is a dynamic exposure throughout life. To provide more insight into the association between body mass index (BMI) and postmenopausal breast cancer, we aimed to examine the age at onset, duration, intensity, and trajectories of body fatness in adulthood in relation to risk of breast cancer subtypes.<p> <p>Methods - Based on self-reported anthropometry in the prospective ...
