The association of adolescent to midlife weight change with age at natural menopause: a population study of 263,586 women in Norway.

Age at menopause varies considerably among women and is linked to health after menopause. Body mass index is associated with age at natural menopause, but the influence of weight change remains unclear. Thus, we studied associations of adolescent to midlife weight change with age at natural menopause.

Validity of self-reported number of pregnancies and maternal age at first birth among females attending organized mammographic screening.

Aims: Reproductive history conveys information about potential health risks later in adulthood. This study aimed to examine the validity of self-reported number of pregnancies and maternal age at first birth (AFB) among females attending BreastScreen Norway.

Methods: Participants were identified through the Janus Serum Bank cohort in Norway and were eligible for this cross-sectional validation study if they participated in a health survey issued by BreastScreen Norway between 2006 and 2015.

Artificial Intelligence Algorithm for Subclinical Breast Cancer Detection.

Importance: Early breast cancer detection is associated with lower morbidity and mortality.

Objective: To examine whether a commercial artificial intelligence (AI) algorithm for breast cancer detection could estimate the development of future cancer.

Design, Setting, And Participants: This retrospective cohort study of 116 495 women aged 50 to 69 years with no prior history of breast cancer before they underwent at least 3 consecutive biennial screening examinations used scores from an AI algorithm (INSIGHT MMG, version 1.

Women's experience of the information provided along with invitation to participate in BreastScreen Norway.

Objectives: To explore how women aged 50-69 invited to BreastScreen Norway perceived the information provided along with the invitation letter, as well as time spent on reading this information.

Methods: An anonymous questionnaire was sent, as a paper-based form along with a physical invitation letter, or as a link to a digital form in a digital invitation letter, to 84,543 women invited to BreastScreen Norway in 2022. The paper-based forms were handed in upon screening attendance.

Breast cancer-specific survival among immigrants and non-immigrants invited to BreastScreen Norway.

Introduction: We have previously shown that immigrants have lower attendance in BreastScreen Norway than non-immigrants and that non-Western immigrants have lower incidence of breast cancer, but more advanced disease.

Purpose: To compare breast cancer-specific survival for immigrants versus non-immigrants diagnosed with screen-detected or symptomatic breast cancer.

Material And Methods: We analyzed data from 28,320 women aged 50-69 diagnosed with breast cancer after being invited to BreastScreen Norway.
