Hi,
BIRADS was developed by the American College of Radiologists as a standard of comparison for rating mammograms and breast ultrasound images. It sets up a classification for Level of Suspicion.
BIRADS 4 is not characteristic of breast cancer, but reasonable probability of being malignant.A biopsy is usually followed.
Having an A added to the score 4 means that the abnormality is less suspicious than if it was 4C.
Many BIRADS 4 return a benign finding and I hope the same for you too.
Best wishes and good luck!
