Breast cancer screening

IKNL monitors the performance of the breast cancer screening program in The Netherlands on behalf of the National Institute for Public Health and the Environment (RIVM). Every year, IKNL provides a report containing the most important outcomes of the population screening compared to previous years. This report, called the Monitor, includes performance on participation, the number of referrals and the number of deviations found.

The National Breast Cancer Screening Programme (website National Institute for Public Health and the Environment; RIVM) is designed for women between 50 and 75 years of age. Once every 2 years, women in this age group are invited for a mammogram. In The Netherlands approximately 14,000 women per year are diagnosed with invasive breast cancer and approximately 2,400 with in-situ breast cancer. The average age at the time of diagnosis is approximately 61 years.

Each year around 3,­000 women die as a consequence of breast cancer. Approximately 1 in 8 women in the Netherlands will develop breast cancer at some point in their lives. This makes breast cancer the most prevalent type of cancer in the Netherlands, with a ten-year prevalence of 128,000.
