Many moms wonder about the link between breastmilk and cancer. Research shows that breastfeeding can lower the risk of certain cancers for mothers, and it may also provide protective effects for babies. While feeding choices are personal and depend on many factors, it helps to know what science says about these health benefits.

How Breastfeeding Affects Cancer Risk for Moms

• Breastfeeding is linked to a lower risk of breast cancer.

• It may also lower the risk of ovarian cancer.

• The longer a woman breastfeeds over her lifetime, the stronger the protective effect may be.

• Hormonal changes during breastfeeding may delay periods, lowering lifetime exposure to estrogen, which is linked to cancer growth.

Breastmilk and Cancer Protection for Babies

• Breastfed babies may have a lower risk of childhood leukemia.

• Antibodies and immune factors in breastmilk help protect against infections, which supports long-term health.

• Breastfeeding also promotes healthy growth, which can reduce risk factors for some diseases later in life.

Other Health Benefits of Breastfeeding

• Boosts baby’s immune system.

• Supports bonding and emotional connection.

• Provides ideal nutrition for growth and development.

• May reduce mom’s risk of type 2 diabetes and heart disease.

What If Breastfeeding Isn’t Possible?

Not every parent can or chooses to breastfeed, and that’s okay.

• Infant formula is a safe and healthy alternative.

• Talk with your pediatrician about the best feeding options for your baby.

• Remember: love, care, and attention are the most important parts of raising a healthy child.
