Just recently had a mammo and ultrasound she said that there is a adnormal spot and come back in 6months dotor was checking it from biospy 5months ago?

Code 3 mammogram: In a small percentage of mammograms, after appropriate workup with additional views and ultrasound, the findings cannot be clearly called benign, nor are they worrisome enough for biopsy. These mammograms are called "code 3". Code 1 & 2 are benign, and 4 & 5 are suspicious. If code 3, a 6 month followup evaluation (usually repeat mammogram and ultrasound of just 1 side) is an appropriate step.
