Mammogram Call Back Statistics

GITNUXREPORT 2026

Mammogram Call Back Statistics

With 1.7 million breast imaging callbacks in the U.S. and only 3.7% of screened women ending up with a diagnostic biopsy, this page shows why recall can be common even when cancer is uncommon. You will also see how BI-RADS 4 patterns, DBT versus 2D, and supplemental ultrasound shift recall rates and downstream costs so screening programs can improve performance without flooding patients with avoidable follow-up.

Key Statistics

Statistic 1

1.7 million breast imaging callbacks occurred in the U.S. in 2022 (diagnostic follow-up after screening mammography)

Statistic 2

7.6% of women screened experienced a false-positive mammography result (leading to callback/diagnostic workup)

A meta-analysis found that breast cancer screening increases the probability of false-positive results (including recalls)

Statistic 6

A Cochrane review reported higher rates of false positives with screening mammography compared with no screening

Statistic 7

A small fraction of recalled cases are cancers, so positive predictive value for recall is low relative to recall volume

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.

How We Rate Confidence

Models

Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
