Cancer Drug -- new one that might be effective

If you, or a person you know, has prostrate cancer, you might want to tell them about this new (I think new) drug treatment.  It works in a different way than prior chemo treatments.  A very good friend of mine has just tried this and says it is effective. I think he might be among the first to use it.  He is what he says:

"The Treatment is called  Zytiga , is a daily pill and works to block the food source to the cancer cells.  Therefore, chemo side effects don't seem to be present."
