Summary
Breast cancer screening in France poses a minimal risk of radiation-induced cancer. Population attributable risk (PAR) from screening mammography is very low, emphasizing continued dose reduction efforts.
Area of Science:
- Oncology
- Radiology
- Public Health
Background:
- Breast cancer screening offers clinical benefits but involves ionizing radiation (IR) exposure.
- Vigilance regarding screening protocols and radiation doses is crucial.
Purpose of the Study:
- To estimate the population attributable risk (PAR) of radiation-induced breast cancer in France in 2019.
- To assess the risk from past IR exposure through screening in women aged 40-74.
Main Methods:
- Reconstituted breast cancer screening practices from 1980-2019 using French National Health Data System and literature.
- Modeled absorbed glandular doses and estimated excess breast cancer cases using two radiation-risk models.
Main Results:
- Approximately 27 breast cancer cases (PAR 0.048%) in 2019 were linked to IR from screening mammography in women aged 50-74.
- An additional 16 cases (PAR 0.030%) were attributed to screening in women aged 40-49.
Conclusions:
- Breast cancer screening's contribution to the overall breast cancer burden in France is minimal.
- Continued efforts to minimize radiation dose during screening mammography are essential.
