This information will help you prepare for your surgery or procedure at Memorial Sloan Kettering (MSK) while you’re breastfeeding or lactating.
Before Your Surgery or Procedure
- Talk with your healthcare team about the different types of medication that you will receive before, during, and after your surgery or procedure. By talking with them ahead of time, they can support you throughout your care.
- Let your child’s pediatrician know that you will be undergoing a procedure that may require anesthesia (medication to make you sleep during surgery) or other medications.
If you have questions about any of the medications you will receive, there are resources that can help:
- Infant Risk Center
You can find information on the use of medications during pregnancy and breastfeeding.
- TOXNET Drugs and Lactation Database (LactMed)
You can find information about medication and other chemicals that can be passed on to your infant from breast milk.
- If possible, pump and store a supply of breast milk before your surgery or procedure. Storing your breast milk ahead of time will allow your baby to continue to be fed your breast milk while you’re separated.
- If you expect to stay in the hospital for more than 24 hours, make arrangements with a family member or friend to bring your pumped breast milk home each day.
- Your breast milk can be stored in an insulated cooler bag with ice packs for 24 hours. Keep the ice packs in contact with the milk containers at all times, and open the cooler bag as little as possible.
- If you can’t send your milk home each day, you can store it at our Memorial Hospital location (1275 York Avenue) and Josie Robertson Surgery Center (1133 York Ave). Breast milk may be stored on site for up to 4 days.

The Day of Your Surgery or Procedure
Plan to breastfeed or pump right before your surgery or procedure. This will help maintain your milk supply and prevent pain and breast engorgement (when your breasts overfill with milk and become firm and swollen).
- Your own breast pump with power source
- All the supplies you need for milk expression (removing milk from your breasts)
- Milk storage containers
- A cooler bag with ice packs (to store pumped breast milk)
Your breast pump will be inspected for safety by our biomed technician. Usually, this can be done at the bedside, but they may need to take the pump away for a moment to inspect it.
If your personal breast pump stops working or fails the inspection, there are some hospital breast pumps available for you to use at Memorial Hospital (1275 York Avenue) and Josie Robertson Surgery Center (1133 York Ave).
On the day of your surgery or procedure, tell your healthcare team that you’re breastfeeding or lactating and wish to continue.Back to top
After Your Surgery or Procedure
Anesthesia doesn’t stay in your body for very long. If you have questions about the anesthesia you received, talk with your anesthesiologist.
You should plan to start pumping again as soon as you’re awake and able. If you need help, ask a member of your healthcare team. You may also want to ask your family or friends for help as you recover from your surgery or procedure.
While you’re separated from your baby, plan to pump every 3 to 4 hours, or at least as often as your baby feeds. Pumping frequently will help maintain your supply of breast milk until you’re able to breastfeed again.
If you have questions about any of the medications you will receive after your surgery or procedure, talk with your healthcare provider. You can also check the websites or call the number listed under the “Before Your Surgery or Procedure” section.Back to top
