You will need to have blood drawn a few days prior to your surgery to check your blood count and to make sure you do not have anemia or an infection. You also may need a mammogram. Your physician will generally give you some prescriptions for pain medication, as well as a muscle relaxer, and an antibiotic. Go ahead and have these filled prior to surgery.
You will need to be NPO after midnight on the night before your surgery, which means you will not be able to eat or drink anything after midnight. You will need someone to drive you home and stay with you for the first night, as you will be groggy and sore. You may need to wear a sports bra for the first 6 weeks. I recommend bras and shirts that button or zip in the front.
