Karolinska Mammography Project for Risk Prediction of Breast Cancer (KARMA)
The KARMA project is a prospective cohort study comprising women attending mammography screening or clinical mammography at four hospitals in Sweden. Since 1994, all women in Sweden, aged between 40 and 74 years, are invited every 18 to 24 months to the national mammography screening programme. All women invited for screening from January 2011 to March 2013, at four hospitals across Sweden, were invited to participate in the study. Additionally, women who had a clinical mammography at any of the participating mammography screenings centres during this time were also invited. During the recruitment period, a total of 210,233 women were invited to participate in the KARMA study and 70,877 women (34%) joined the study.
