What could a call to go back to the surgeon mean after a lumpectomy?

Need more surgery: This could mean that the surgical area has positive margins-i.e. There is still part of the mass/tumor left. You want negative margins which means all of the tumor is gone. I highly recommend you contact your surgeon to speak about this in detail. An in-person visit will allow you to get all of your questions answered. Take a friend or family member as an extra pair of ears.
