Indication:  Prostate cancer cells rely on testosterone, the male hormone, to grow and spread. Eulexin works to prevent the testosterone from doing their job and, in effect, slows the growth. Known as a hormone therapy drug, this medication is given with other drugs and radiation treatment to stop the cancer from spreading.
