Description

Women 50-69 years of age are invited by personal letter to take part in breast cancer screening, or mammography, every two years.

More than 80% of the women invited to attend are screened. Fewer than 3% of participants are invited for further testing, i.e. ultrasound examination and biopsy, and of the individuals invited for further testing about 20% have breast cancer.

A total of about 5000 women in Finland each year are diagnosed with breast cancer. Of those, over half belong to the screening age group of 50-69. Some two-thirds of female breast cancers are detected by screening.

FinnGen breast cancer screening data consists of measurements of breast cancer screening (e.g. radiologists’ reports, biopsy, surgery), since 1992.

More information about the data is available from the Finnish Cancer Registry (Breast cancer screening).
