Dear gayegjones, The radiologist is interpreting this mammogram as a probably benign finding by giving it a BI-RADS rating of 3. Recommendations in this category are generally short-term follow-up to establish stability
of the finding. Follow up with a breast surgeon to evaluate the mammograms, comparing this to baseline and give a second opinion based on all the testing and physical exam, makes sense. You would want to discuss the findings with the breast surgeon, as well as their recommended follow-up for your individual situation.
Everyone wants to err on the side of caution with breast issues. When calcifications have lucent centers, it means they are most certainly little calcified cysts, and harmless. To get a six-month followup is being very cautious; likewise, getting a surgeon's opinion. Gyn's often like to let a surgeon be the one to have the last word. It's good to have doctors that are very cautious. It also sounds like your mammogram and ultrasound have made it very clear that cancer is as well-ruled out as it can be short of a biopsy.
