如pickshell和葉蓁所說，category 4提示異常可能。統計說30%的category4最後確認異常

"The BI-RADS assessment categories are:

  • 0- incomplete
  • 1-negative
  • 2-benign findings
  • 3-probably benign
  • 4-suspicious abnormality
  • 5-highly suspicious of malignancy
  • 6-known biopsy with proven malignancy

A BI-RADS category 4 mammogram has a positive predictive value of about 30%. A category 5 mammogram is almost certainly predictive of breast cancer with a positive predictive value of about 95%."
