A natural extract from beehives has been demonstrated to have a positive effect on the development of prostate cancer.
Scientists at the University of Chicago Medicine explained that caffeic acid phenethyl ester - the resin used by bees to patch up holes in a hive - can prevent tumour cells receiving adequate nutrients during the early stages of the disease.
Richard Jones, assistant professor in the Ben May Department for Cancer Research and Institute for Genomics and Systems Biology and senior author of the study, said: "After several weeks, if you stop the treatment, the tumours will begin to grow again at their original pace.
"So it doesn't kill the cancer, but it basically will indefinitely stop prostate cancer proliferation."
Even low concentrations, which would be the case after oral administration, were shown to have a positive effect on the growth of cancer. Doctors suggest it could be used alongside chemotherapies, which aim to actually kill the cells.
