Drug compound kills breast cancer stem cells

U.S. researchers have discovered a **compound** that can kill **breast cancer** stem cells, a kind of master cancer cell that resists conventional treatment and may explain why many cancers grow back, they reported on Thursday. The **discovery** came using a new method of screening for drugs that **specifically target** and kill cancer stem cells, and it could be used to find drugs targeting other cancer stem cells as well, they said. Many teams have been looking for ways to destroy these master cancer cells in hopes of making cancer easier to cure. "Reuters":[ http://www.reuters.com/article/scienceNews/idUSTRE57C4XA20090814]
