Prior to your procedure, you may be asked to get lab tests, a medical evaluation, or a baseline mammogram. You might be asked to get another mammogram after your procedure so your care providers can better understand future changes to your breasts. (Not sure where to go to get your lab tests?

If you smoke, you’ll probably be asked to stop for several weeks or months, and you’ll also likely be instructed not to take aspirin, anti-inflammatory drugs, and herbal supplements because they can increase bleeding. Your surgeon will also likely tell you not to eat anything after midnight on the day of your surgeries.
