High doses of the hormone progesterone can kill neuroblastoma cells while leaving healthy cells unscathed, scientists at Emory University School of Medicine have found in laboratory research. The results, published in the journal Molecular Medicine, suggest that progesterone could be used to fight neuroblastoma, the most common form of cancer affecting small children. More research is necessary to determine the optimal dose, how long progesterone treatment should last and if it should be used alone or in combination with radiation or chemotherapy. Emory scientists are also exploring whether it can stop the growth of other brain cancer types such as...
