What do I need to know about breast reconstruction?

Breast reconstruction is surgery to rebuild one or both breasts with implants. Breast reconstruction may be done at the same time as a mastectomy or in a separate surgery. You may need to have a tissue expander, or balloon like sac, placed in each breast before an implant is placed. Expanders are slowly filled with saline over 2 to 3 months. This helps stretch the tissue and make room for an implant. The tissue expander may be removed and replaced with an implant in a later surgery. Saline (salt water) implants, silicone gel implants, or a combination may be used to rebuild the breast.

How do I prepare for breast reconstruction?

Your healthcare provider will talk to you about how to prepare for surgery. You may need to stop taking blood thinners or aspirin several days before surgery. Your provider may tell you not to eat or drink anything after midnight on the day of your surgery. He or she may tell you to shower the night before your surgery. He or she may tell you to use a certain soap to help prevent a surgical site infection. He or she will tell you what medicines to take or not take on the day of your surgery. Ask your healthcare provider if you will need to stay in the hospital after surgery. Arrange for someone to drive you home and stay with you for 48 hours. They may need to help you cook, bathe and dress. They can call 911 or drive you to the hospital if there is a complication from surgery.

What will happen during breast reconstruction?

You will be given general anesthesia to keep you asleep and free from pain during surgery. You may be given an antibiotic through your IV to help prevent a bacterial infection. If you are having an expander placed, your healthcare provider will make an incision and insert the expander under your muscle. If an implant will be placed, your healthcare provider will make an incision in your breast and make a space under the chest muscle. The implant will be placed into the space. Your healthcare provider may insert 1 or more drains near the incision to help remove extra fluid. This may prevent swelling and help your incision heal. He or she will close your incision with stitches and cover it with a bandage.

What will happen after breast reconstruction?
