MedicalResearch.com: What are the main findings of the study?
Dr. Hofvind: We find that if 100 women aged 50 years attend the Norwegian Breast Cancer Screening Program as recommended, every two years until they are 69 years, four women will undergo a needle biopsy with benign outcome (a false positive needle biopsy).
In the same group of women, twenty women will be recalled for further examination and have additional imaging, ultrasound, and/or a biopsy with negative outcome (a false positive screening result).
MedicalResearch.com: Were any of the findings unexpected?
Dr. Hofvind: The results are an agreement with findings from European screening programs, but the cumulative risk is substantial lower as reported from the U.S.
MedicalResearch.com: What should clinicians and patients take away from your report?
Dr. Hofvind: False positive screening results are not a substantial harm in mammographic screening, as performed in Norway and most European countries.
MedicalResearch.com: What recommendations do you have for future research as a result of this study?
Dr. Hofvind: We need to investigate the risk of cancer in women who have a false positive screening results. Do they run a higher or lower risk of breast cancer?
