Delayed Post-Mastectomy Prosthetic Breast Reconstruction


Post-mastectomy breast reconstruction is done weeks after one or both breasts have been removed. If a tissue expander (balloon-like sac) was placed during the mastectomy to help stretch the skin and tissue, it will be removed. Caregivers will also place a permanent breast implant to help shape the breast.


The week before your surgery:

  • Arrange to have someone drive you home after your surgery. Do not drive yourself home.
  • Ask your caregiver if you need to stop using aspirin or any other prescribed or over-the-counter medicine before your procedure or surgery.
  • Bring your medicine bottles or a list of your medicines when you see your caregiver. Tell your caregiver if you are allergic to any medicine. Tell your caregiver if you use any herbs, food supplements, or over-the-counter medicine.
  • You may need to donate blood before your surgery. Your blood is stored in case you need it during or after your surgery.
  • You may need to have blood and urine tests, a mammogram, chest x-rays, or other tests. Ask your caregiver for more information about these and other tests that you may need. Write down the date, time, and location of each test.
  • Write down the correct date, time, and location of your surgery.

The night before your surgery:

  • You may be given medicine to help you sleep.
  • Ask caregivers about directions for eating and drinking.

The day of your surgery:

  • Ask your caregiver before taking any medicine on the day of your procedure. These medicines include insulin, diabetic pills, high blood pressure pills, or heart pills. Bring a list of all the medicines you take, or your pill bottles, with you to the hospital.
  • Caregivers may insert an intravenous tube (IV) into your vein. A vein in the arm is usually chosen. Through the IV tube, you may be given liquids and medicine.
  • An anesthesiologist will talk to you before your surgery. You may need medicine to keep you asleep or numb an area of your body during surgery. Tell caregivers if you or anyone in your family has had a problem with anesthesia in the past.
  • You or a close family member will be asked to sign a legal document called a consent form. It gives caregivers permission to do the procedure or surgery. It also explains the problems that may happen, and your choices. Make sure all your questions are answered before you sign this form.


What will happen:

  • You may be given medicine to help you relax or make you drowsy. You may also get anesthesia medicine to keep you completely asleep during surgery.
  • Caregivers will make an incision in your breast area. If you have a tissue expander, caregivers will remove it and replace it with the permanent breast implant. The implant will be placed in the area where the expander was taken. Thin rubber tubes may be put into your skin to drain blood from your incision. The incisions will be closed with stitches and covered with bandages.

After your surgery:

You will be taken to a room where you can rest until you are fully awake. Caregivers will monitor you closely. Do not try to get out of bed. When caregivers see that you are okay, you will be taken to your hospital room.


  • You cannot make it to your surgery on time.
  • You have a fever.
  • You feel a new lump in your chest, other breast, or under your arm.
  • You see or feel other changes in your breast.
  • You have a skin infection or an infected wound near the area where surgery will be done.
  • You have questions or concerns about your surgery.


You may bleed more than expected or get an infection after surgery. You may get a blood clot in your arm or leg. The clot may travel to your heart or brain and cause life-threatening problems, such as a heart attack or stroke. An implant may become less attractive over time. Scar tissue may form around the implant. The implant may wear out, burst, or leak. You may need to have more surgeries later on. The reconstructed breast may have scars and not be as sensitive as it was before.
