Palpable breast abnormalities in women under age 40

Area of Science:

• Radiology
• Oncology
• Breast Imaging

Background:

• Management of palpable breast abnormalities in women under 40 is controversial.
• Malignancy prevalence is low in this demographic, yet benign findings pose diagnostic challenges.

Purpose of the Study:

• Assess imaging evaluation, management, and outcomes for women under 40 with palpable breast abnormalities.
• Evaluate the cost-effectiveness and outcomes of BI-RADS 3 assessments in this patient group.

Main Methods:

• Retrospective review of 1440 cases of women under 40 with palpable breast abnormalities (July 2010-June 2013).
• Diagnostic imaging, BI-RADS assessment, and outcomes (tissue diagnosis, 2-year surveillance, tumor registry) were analyzed.
• Performance measures including sensitivity, specificity, and predictive values were calculated.

Main Results:

• Breast cancer prevalence was 2.1% (30 malignancies), all categorized as BI-RADS 4 or 5.
• No BI-RADS 1, 2, or 3 findings were malignant.
• Imaging demonstrated 100% sensitivity and 100% negative predictive value for malignancy.

Conclusions:

• Average-risk women under 40 with palpable abnormalities have a low malignancy risk.
• Imaging is highly sensitive and specific, enabling confident characterization and management.
• Short-term follow-up for palpable solid masses with benign imaging features is a safe, cost-effective alternative to biopsy.
