Breast imaging callbacks are not a rare side effect anymore, with 14.6% of women in one modeling study experiencing at least one false positive recall within 10 years. Those recalls send people into diagnostic workups, and for many the result is BI-RADS 4 suspicion or a biopsy without cancer rather than a true malignancy. So while 7.6% of screened women face a false positive result, the key tension is how much of that downstream effort changes cancer detection versus how much simply increases callbacks.
Key Takeaways
- 1.7 million breast imaging callbacks occurred in the U.S. in 2022 (diagnostic follow-up after screening mammography)
- 7.6% of women screened experienced a false-positive mammography result (leading to callback/diagnostic workup)
- A 10-year randomized screening study reported that about 4 in 10 women had at least one false-positive mammogram result (callback/diagnostic workup)
- The U.S. Preventive Services Task Force notes that screening mammography leads to false-positive results for many women, including those who are recalled for further testing
- 3.7% of screened women in a large U.S. study received a diagnostic biopsy after a screening mammogram
- 2.1% of screening mammograms in a U.S. population-based cohort led to benign biopsy (biopsy without cancer)
- BI-RADS 4 is suspicious and commonly triggers biopsy, contributing to higher diagnostic follow-up after callbacks
- Diagnostic imaging after callback has measurable downstream effects on radiation dose and patient throughput
- The U.S. Medicare program covers diagnostic mammography and follow-up evaluations after abnormal screening, affecting callback care pathways
- Diagnostic workup after abnormal screening contributes substantially to out-of-pocket costs and utilization of imaging and procedures
- DBT vs 2D: randomized trials show lower recall rates, directly improving performance metrics for screening programs
- DBT reduced recalls by 15% in a large U.S. randomized trial reported in 2019 (vs 2D mammography)
- A systematic review found DBT reduces the rate of women recalled for further testing compared with full-field digital mammography
- Commercial radiology workflow software market size for breast screening and imaging informatics reached $X billion in 2023 (imaging informatics category)
- The global AI in medical imaging market was valued at $1.4B in 2021 and is projected to grow substantially, supporting increased tools that may affect callback rates
In 2022, millions of U.S. callbacks from screening mammograms were false alarms, driving costly follow ups.

A meta-analysis found that breast cancer screening increases the probability of false-positive results (including recalls)
05
A Cochrane review reported higher rates of false positives with screening mammography compared with no screening
06
A small fraction of recalled cases are cancers, so positive predictive value for recall is low relative to recall volume

14.6% of women with screening mammograms had at least one false-positive recall within 10 years in a modeling study
08
A UK analysis reported that among women recalled for assessment, cancer positivity rates were low relative to recall volume
Interpretation
Clinical Effectiveness Interpretation
From a clinical effectiveness perspective, false-positive callbacks are common despite screening, with about 7.6% of women experiencing false positives and modeling suggesting 14.6% had at least one false-positive recall within 10 years, while only a small fraction of recalls are actual cancers.

In a randomized trial, supplemental ultrasound for women recalled after screening mammography increased cancer detection but also increased biopsies and callbacks
Interpretation
Diagnostic Pathways Interpretation
In Diagnostic Pathways, follow-up after screening is far from rare, with 3.7% of screened women receiving a diagnostic biopsy and 2.1% ending up with benign biopsies, showing how BI-RADS 4–driven suspicions and added ultrasound can raise cancer detection while also increasing callbacks and biopsies.
