Typically in the US, we order ultrasounds in women under 30 and mammograms over 30 years old. The radiologist then categorizes the mass using BI-RADS (Breast Imaging Reporting and Data System). The higher the number the higher risk for an abnormality and recommendation for biopsy. Cancer risk is based on the individual's symptoms, pregnancies and family history. The biopsies will provide answers
