Breastfeeding after breast surgery

Breast surgery is an operation that removes or reconstructs breasts for cosmetic reasons, or medical reasons like breast cancer, pain or emotional problems.

Types of breast surgery include:

• mastectomy (Opens in new tab) (surgical removal of the breast)
• breast reduction (Opens in new tab)
• breast augmentation (Opens in new tab) (breast implants)
• breast reconstruction with breast implants (Opens in new tab) or tissue flap (Opens in new tab)
• breast lift (Opens in new tab) (mastopexy)

Having breast surgery can affect breastfeeding and your milk supply. How much these are affected depends on:

• the type of surgery
• any changes to the breast structure or nipple
• effect on the nerve supply to the nipple and areola
• disruption to milk glands or ducts

You may be able to breastfeed following surgery or continue breastfeeding once you are well enough and rebuild your supply.

Following surgery, you may be able to:

• fully breastfeed (without the need for top-up feeds)
• partially breastfeed (some top-up feeds needed)
• breastfeed with the help of medicines to boost your milk supply

It's important to speak to your surgeon about your breastfeeding plans before surgery so they can do the surgery in a way that can help you breastfeed in the future.

Getting proper support is important. Speak with a breastfeeding counsellor or lactation consultant after your surgery or before the birth of your child if you have had breast surgery. They can help you begin breastfeeding or help you continue breastfeeding after breast surgery.

Breastfeeding is possible if you have implants. Your ability to breastfeed if you have implants will depend on:

• the surgery technique
• where the surgical cuts are
• impact on milk ducts and nerves

Your ability to breastfeed will depend on if you have had a double mastectomy, single mastectomy or partial mastectomy.

You may be able to breastfeed on the unaffected breast if you have had a mastectomy or partial mastectomy. You may also be able to partially breastfeed on the affected side following a partial mastectomy.

If you have had or are having a double mastectomy you will not be able to breastfeed following surgery.

Speak with your doctor if you need a mastectomy and hope to breastfeed.

Unfortunately, it will not be possible to breastfeed from your reconstructed breast. If you have only had one breast reconstructed you may be able to breastfeed successfully with the other breast.

A breast care nurse or lactation consultant can answer any questions you have about breastfeeding after a reconstruction.

Sometimes you can have breast surgery while breastfeeding, but it is important that your doctor knows that you are breastfeeding your baby. They can make plans to help you successfully continue breastfeeding such as by deciding what medicines to prescribe before, during or after your surgery so breastfeeding is safe. They may also be able to change the way they do the surgery.

Most anaesthetics and pain-relief medicines are safe to take, since they pass into your breastmilk at very low levels. You do not usually need to throw away any of your pumped breastmilk. Sometimes this is called "pump and dump". If you need strong pain medicine or your baby is premature or sick, you should check with your doctor about your specific situation.

Stress or pain can affect how you make a hormone called oxytocin. Oxytocin controls your milk let-down reflex. It is important that you speak to your doctor about suitable pain relief to help manage your pain after surgery.

You may need to fast before your surgery or you could be separated from your baby for a time. It is important you discuss this with your doctor and prepare for situations like these. You may need to express and store breast milk or feed your baby formula.

Make sure you discuss with your doctor:

• how to keep hydrated and protect your milk supply
• the length of your surgery and if you need to feed or express before your procedure

You should ask your doctor before your surgery about how the surgery could affect your ability to breastfeed your baby.

There are signs that your baby is getting enough milk, such as:

• your baby has plenty of pale yellow, heavy and wet nappies
• your newborn baby has at least one bowel movement every day
• your baby is gaining weight (after some expected weight loss soon after birth)
• your baby has bright eyes, a moist mouth and good colour

If you are worried your baby is not getting enough milk you should speak to your doctor, lactation consultant, or a child and family health nurse.
