You’ve Had Breast Surgery — Will That Impact Your Ability To Breastfeed?

Severed milk ducts or lost glandular tissue may affect your milk production

The female anatomy of a breast is incredibly complex. Filled with fatty deposits, sensitive nerves, connective tissues and glandular tissue that produce milk, there’s a lot all packed tightly together in one place.

If you’re pregnant or breastfeeding (chestfeeding), any sort of previous breast surgery may have a direct impact on how much breast milk you can produce, how much can be stored in your breasts and whether or not it flows easily down mammary (milk) ducts before exiting through your nipple.

Pediatrician and breastfeeding medicine specialist Heidi Szugye, DO, IBCLC, explains some of the complications that can arise from having breast surgery, along with ways to increase and make the most of the milk supply you have.

Breastfeeding with implants/after augmentation

When you have breast augmentation surgery you’re changing the appearance of your breasts with the help of implants or fat transfers. Often, a breast lift might be done in conjunction with implants to better position parts of your breast or lift them higher on your chest.

“The location, type and size of the implant can all be factors in how much milk production will be affected,” says Dr. Szugye. “But we do know that breast augmentation surgery itself can cause vascular and nerve damage and that can also affect supply.”

All breast surgeries are done in such a way as to try to reduce the effect they might have on lactation. But with breast augmentation specifically, it’s important to note that you can’t really increase the amount of glandular tissue responsible for milk production — if anything, you may lose some of that tissue as part of the process or have to rely on the tissue you’ve always had.

“If you have more tubular-shaped breasts or very wide-spaced breasts, that can be a sign that you were born with less of that glandular tissue that makes the milk,” explains Dr. Szugye. “Having a breast augmentation changes the appearance of your breasts, but it doesn’t increase the amount of tissue that was there to begin with.”

You can breastfeed after having breast augmentation, and breastfeeding with implants is safe. But keep in mind that the farther out from surgery that you start breastfeeding, the higher the chances that your milk supply will be sufficient.

In addition, a baby can sometimes have more difficulty latching to very large breasts, so getting support from a breastfeeding medicine specialist or lactation consultant before delivery can be helpful.

Breastfeeding after breast reduction

Breast reduction is different from augmentation, as the main goal is to decrease the size of your breasts by removing fat, skin and other tissues. You can breastfeed after having a breast reduction, but the procedure involves a higher chance of impacting your ability to produce breast milk because of the removal of important tissue.

“Your supply of milk is less affected if the nipple and areola remain attached to the breast during surgery,” notes Dr. Szugye.

On average, you have about nine milk ducts per nipple, and severing just one can have long-term effects on expressing milk.


“The tissue might be there and the milk might be created, but that pathway from the sacs that make the milk out to the nipple can sometimes be severed,” explains Dr. Szugye. “If the milk is produced but it has a hard time getting out, that can, unfortunately, cause some engorgement and swelling until the body recognizes the milk isn’t going anywhere.”

The process of your body ridding itself of that unused milk can take a couple of weeks, so Dr. Szugye often recommends using ibuprofen (a medication that’s safe to take while breastfeeding) and cold compresses to help reduce inflammation.

Otherwise, if you’ve had a breast reduction and are struggling to produce enough milk during feedings, you can supplement feedings with breast milk from a donor or use formula instead. In fact, there are many ways to still allow your baby to get breast milk and any amount of breast milk is beneficial.

We recommend reaching out to a breastfeeding medicine specialist during pregnancy to help maximize your breast milk supply ahead of delivery and to establish the support you need.

Other breast surgeries or procedures that might impact breastfeeding

Breast cancer surgery includes the removal of small tumors (lumpectomy) and in some cases, entire breasts (mastectomy). Both surgical procedures can lead to the removal of milk ducts and glandular tissues that produce breast milk.

Radiation therapy and chemotherapy may also be used before or after surgery or even as a replacement for surgery, but that can also have a lingering impact on whether or not you’re able to produce milk that’s safe for consumption.

“If a nursing parent doesn’t need chemotherapy and just requires surgical intervention, then we’ll often try to preserve the breastfeeding experience as much as possible,” says Dr. Szugye. “We’ve had nursing parents breastfeed out of one breast if no radiation or chemotherapy is needed.”

If radiation is required, that breast won’t, unfortunately, produce milk in the future. Most chemotherapy regimens don’t allow for continued breastfeeding due to harmful effects on your baby and the risk of developing severe mastitis (inflammation of the breast) while you’re immunocompromised.

If you’ve had cancer treatments or you’re going through the treatment process, your healthcare team can discuss your options with you and help you find the support you need.

What can you do to increase milk supply?

The key to establishing a good milk supply is getting as much milk as possible out of your breasts during the first two to three weeks after delivery.

“It’s really about supply and demand,” says Dr. Szugye. “If you’re frequently stimulating and emptying your breasts early on, we’re going to recruit all those cells that are there to make milk.”


Early on, this means you want to put your baby to your breast every two to three hours each day. Hand-expressing your breast milk after feedings can also help increase your milk supply long term.

“It’s really important early on that you’re setting yourself up for success,” encourages Dr. Szugye. “One important thing to keep in mind is that breastfeeding doesn’t need to be all or nothing, either. We can still help nursing parents reach their breastfeeding goals by maximizing their breast milk or having that at-the-breast experience.”

The breastfeeding experience is different for everyone. Generally, you want to try and maximize the amount of breast milk you can give through bottle feeding or directly from your breast, and then rely on supplementing your breast milk with FDA-approved formula as needed.

Nursing parents may also value the time that the baby is skin-on-skin with them, even if your baby isn’t getting most of their nutrition from suckling because it provides a number of other benefits.

“Successful breastfeeding does not always mean producing a full supply of milk,” notes Dr. Szugye. “Nurturing your baby at the breast can be fulfilling, even with the use of a supplemental feeding device.”

What to know about supplementing

You can feed your baby expressed milk or formula, if needed. Supplemental nursing systems use tube feeding to help supplement milk from the breast. The system is made up of a container that has supplemental liquid. A tube runs from the container to the nipple of the breast, allowing your baby to suck on your nipple and the tube at the same time.

However you choose to supplement your supply of breast milk, it’s always good to meet with your pediatrician or a breastfeeding medicine specialist to talk about the surgeries you’ve had, any complications or challenges you’re facing, and alternative methods to breastfeeding that interest you. Doing so may lead to even better solutions along the way — and might even highlight other issues or conditions that are affecting your milk supply.

“You may have had breast surgery before, but if you also have conditions like thyroid dysfunction or polycystic ovarian syndrome or other factors that might be influencing your supply, we want to make sure those aren’t also complicating the low supply issue,” Dr. Szugye states.

“It’s always good to see a breastfeeding medicine specialist if you’ve had surgery because we can help mitigate any of the possible variables that might reduce your supply.”
