Case 5 Answer 4

A 6-month follow-up exam should be performed for all benign needle biopsies. There is a small risk of sampling error. By performing the needle biopsy, we have reduced the probability of malignancy from about 20% in this case to less than 2%. In the unlikely event that the target was missed and cancer was present, we should catch it at the follow-up appointment.

Another advantage to placing the clip is that the technologists and radiologist who perform and interpret the 6-month follow-up diagnostic mammogram will have no question as to what area is being followed.
