Researchers in Sweden have discovered a compound in breast milk that can kill cancer cells in human beings.
"Human Alpha-lactalbumin Made LEthal to Tumor cells" is what they're calling it for now, with its acronym HAMLET. This newly-discovered HAMLET is made up of a protein and a fatty acid, and is found to naturally occur in breast milk.
The researchers gave HAMLET to patients who had bladder cancer. Later they found that dead cancer cells were expelled in the patients' urine.
Apparently HAMLET binds to the membranes of tumor cells and kills them, yet manages to do this without causing any sort of disruption to healthy cells in the area.
"The Swedish research team is working to see if the compound can be eventually developed into a viable cancer therapy. Next on their agenda: tests to see if HAMLET can treat skin cancer, a variety of brain tumors and tumors in the mucous membranes."
