Quick background. I have had two steorotypic biopsies. Both came back benign, although the second one showed Atypia. Had surgery last year to remove abnormal cells and currently taking Tamoxifen. Today went in for a nine month follow-up mammogran and mri. Radiologist saw something on the mammogram and than ordered an ultrasound. While the technician was performing the ultrasound, she remarked about seeing something and wanted to know if I opted not to have it removed. Needless to say, she put me in a panic. Could it have been scar tissue that she was referring to?
