During surgery, how does the surgeon find my breast cancer if I can’t feel it?

Your breast surgeon may use different methods to identify “impalpable” cancers during surgery. One method would be to do an ultrasound just before or during surgery. Another method is using a hookwire which is inserted into the breast by a radiologist on the morning of surgery and stays in place until removed at the time of surgery. A third and newer method available at some facilities are “seeds” of which there are several types of, which can also be inserted into the cancer by a radiologist any time prior to surgery, then at the time of surgery a detecting probe is used to find the seed.
