Summary
Brief summary (as posted)
The aim of this observational study is to investigate the association between mid-life changes in cardiorespiratory fitness and the risk of breast cancer incidence and mortality among Swedish women. The main questions to answer are: \- Are changes in cardiorespiratory fitness associated with the risk of being diagnosed or dying from/with breast cancer later in life? Participants performed at least two occupational health assessment tests, which consisted of a submaximal ergometer cycle test, measurement of body mass and height to calculate BMI, and a questionnaires on physical and life style habits.
