Causes of Blood in Breast Milk

Blood in Breast Milk

First things first, you need to know what are the possible causes of blood in breast milk. There are several possible reasons why you would have blood in the breastmilk. These are as follows:

Damaged nipples

Cracked nipples may come as a result of improper latching. When the child doesn’t latch on the right way, it may cause some irritation on your breasts which may lead to pain and cracking. Your cracked nipples may bleed which may cause blood in breast milk.

Broken capillaries

Our breasts have small blood vessels which may break because either injury or trauma which is associated with the expression of breast milk, either by pumping or hand.

Vascular engorgement

Many refer to this as the rusty pipe syndrome. After giving birth to your baby, your breasts will receive a greater amount of blood as it produces breastmilk. This stage is referred to as vascular engorgement.

The excess blood flow during this stage may leak into your breast milk which causes it to have a rust, orange or brown color. This is more common to first-time moms.


This is a type of infection that usually occurs when breastfeeding. This condition is associated with a build-up of milk in the breasts which causes swelling, breast pain, redness, chills, and fever. Some women with mastitis also experience nipple discharge which may lead to the presence of blood in breast milk.

Benign intraductal papilloma

Blood in breast milk may also be a result of the presence of small benign tumors in the milk duct lining. If you are not sure if you have these, try touching your breasts. You may feel these as small growths behind the nipple.

If you only have a single intraductal papilloma, there is nothing to worry about. But if you have multiple papillomas, it is best that you have it checked right away.
