  1. Unless otherwise indicated, data are numbers of patients and data in parentheses are percentages
  2. aExtra-mammary lesions: 2 benign sternal masses (1 biopsied and 1 stable on follow-up) and 1 malignant lung mass (biopsied)
  3. **1 suspicious A-MRI finding was less conspicuous the day of the biopsy, for which follow-up was performed and showed stability
