Different measures of smoking exposure and mammographic density in postmenopausal Norwegian women : a cross-sectional study
Bremnes, Yngve; Bjurstam, Nils; Ursin, Giske; Gram, Inger Torhild (Journal article; Tidsskriftartikkel; Peer reviewed, 2007-10-26)Background: Recent cohort studies have suggested an increased risk of breast cancer with long duration of smoking, and with smoking initiation before first birth. Cigarette smoking may have both carcinogenic effects and antiestrogenic effects on the breast tissue. We decided to examine the relationship between different measures of smoking exposure and mammographic density. Methods: Lifetime ... -

Hormones, smoking and mammographic density in postmenopausal Norwegian women : the Tromsø Mammography and Breast Cancer Study
Bremnes, Yngve (Doctoral thesis; Doktorgradsavhandling, 2007)Breast cancer is the most commonly occurring malignancy among women, and according to estimates by the International Agency for Research on Cancer, more than one million new cases were diagnoscd worldwide in 2002 (1). In Norway, altogether 2,780 women were diagnosed with breast cancer in 2005, corresponding to an age-adjusted (world) incidence rate of 75.7 per 100,000 women per year (2). According ... -
Percentage density, Wolfe's and Tabár's mammographic patterns. Agreement and association with risk factors for breast cancer
Gram, Inger Torhild; Ursin, Giske; Maskarinec, Gertraud; Bremnes, Yngve; Bjurstam, Nils; Lund, Eiliv (Journal article; Tidsskriftartikkel; Peer reviewed, 2005-08-25)Introduction: The purpose of this report was to classify mammograms according to four methods and to examine their agreement and their relationship to selected risk factors for breast cancer. Method: Mammograms and epidemiological data were collected from 987 women, aged 55 to 71 years, attending the Norwegian Breast Cancer Screening Program. Two readers each classified the mammograms according ... -
Plasma levels of leptin and mammographic density among postmenopausal women. A cross-sectional study
Stuedal, Anne; Bremnes, Yngve; Gram, Inger Torhild; Ursin, Giske; Veierød, Marit B.; Reseland, Janne E.; Drevon, Christian A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2006-09-29)Introduction Obesity has been linked to increased risk of breast cancer in postmenopausal women. Increased peripheral production of estrogens has been regarded as the main cause for this association, but other features of increased body fat mass may also play a part. Leptin is a protein produced mainly by adipose tissue and may represent a growth factor in cancer. We examined the association ...
