Breastfeeding with Breast Cancer: Challenges, Facts, and Hope

Laurel Post had a dream — to breastfeed her son for two years. But at 15 months, that dream was interrupted by an aggressive breast cancer diagnosis. Laurel’s reality shifted overnight. Immediate chemotherapy and a double mastectomy left no time to prepare. Her plan to nurse was replaced by a fight for survival.

For many women, balancing breastfeeding and cancer treatment feels like navigating uncharted waters. What happens when a mother, intent on providing the best for her child, faces such an unexpected obstacle? Is breastfeeding possible, or does treatment mean the end of this journey?

Experts say it depends on the circumstances. Breast cancer may change the course, but in many cases, breastfeeding isn’t entirely off the table. With medical guidance, some women can adapt their plans to fit their unique needs and situations.

Surgery alone, without further treatment, often allows mothers to return to breastfeeding. Doctors usually recommend pumping and freezing milk before surgery to maintain supply. However, anesthesia and certain medications can linger in the body, making it essential to consult healthcare professionals before resuming.

For mothers undergoing chemotherapy, the story is different. These potent drugs can pass into breast milk, posing risks to the baby. While breastfeeding during chemo is not advised, mothers can still pump to preserve milk supply, though the milk must be discarded. Unfortunately, for some women, chemotherapy may halt milk production altogether.

Hormone-blocking drugs like tamoxifen, prescribed to prevent recurrence, also bring challenges. These medications transfer through breast milk, making breastfeeding unsafe. Emerging studies suggest that pausing hormone therapy for pregnancy and breastfeeding might be feasible for some women, but this requires close medical supervision.

Radiation therapy, while critical for treating cancer, may complicate breastfeeding. Skin sensitivity and changes to the breast’s elasticity can make latching difficult. Milk from a radiated breast might appear darker or thicker, but it’s generally safe. Many mothers find that one breast can supply enough milk, even for twins. For those with low supply, donor milk or formula can bridge the gap.

The fear of cancer recurrence is another layer of complexity. While concerns are natural, research shows no evidence linking breastfeeding to a return of cancer. In fact, breastfeeding has been shown to reduce the risk of developing breast cancer initially. Survivors should find reassurance in this and focus on their health and well-being.

It’s important to remember that “fed is best.” Whether a baby is breastfed or formula-fed, the ultimate goal is a healthy and thriving child. Studies indicate no significant differences in health or intellect between breastfed and formula-fed infants. For mothers unable to breastfeed due to cancer treatment, bonding with their baby remains a priority. From skin-to-skin contact to loving gazes during bottle feeds, there are countless ways to nurture that special connection.

As for Laurel, the decision to stop breastfeeding was bittersweet. But she knew her fight against cancer was the ultimate act of love for her son. Her story is a testament to the resilience and sacrifices of mothers navigating both motherhood and illness.

When cancer disrupts breastfeeding plans, women face tough choices. Yet, through expert guidance and unwavering determination, many find ways to balance their health with their baby’s needs. Every journey is unique, but one truth remains universal: a mother’s love is the greatest gift she can give.
