Good to know!  A study released last week showed that a breast milk factor killed cancer cells in human cancer patients.  This further fleshes out our growing understanding of the protective effect of breastfeeding against cancer.  We’ve known for awhile that breastmilk in a test tube in a lab could kill cancer cells added to the breastmilk.  That fact has led to speculation that breastmilk may kill cancer cells, not just in the lab, but in humans as well.  Some cancer patients have sought out breastmilk in the hope that it would have a therapeutic effect on their cancers.  But until now, despite speculation that breastmilk may kill cancer cells in humans, we haven’t had any proof to support that.  This study released last week finally provides evidence-based support that what everyone has speculated is true — breastmilk contains factors which actively fight cancer in humans.

A substance found in breast milk can kill cancer cells, reveal studies carried out by researchers at Lund University and the University of Gothenburg, Sweden.

Although the special substance, known as HAMLET (Human Alpha-lactalbumin Made LEthal to Tumour cells), was discovered in breast milk several years ago, it is only now that it has been possible to test it on humans. Patients with cancer of the bladder who were treated with the substance excreted dead cancer cells in their urine after each treatment, which has given rise to hopes that it can be developed into medication for cancer care in the future.
