"malignant: ~20% 1-2"
"Given the 20% positive predictive value of malignancy, most amorphous calcifications are assessed as BI-RADS 4B (suspicious, warranting biopsy) 5. That assessment particularly applies to amorphous calcifications with a grouped, linear, or segmental distribution. However, bilateral diffuse amorphous calcifications may be assessed as BI-RADS 2 (benign). If long-term (2-3 year) stability has been demonstrated, a BI-RADS 2 assessment would also be appropriate."
