ER/PR negative means that the cancer is NOT dependant on Estrogen/Progesterone for it's growth. Cerb2 or HER2/neu positive means that the cancer IS dependant on a particular protein for growth. These cancers are considered to be more aggressive. This type of cancer cannot be treated with hormone therapy but can be treated with Herceptin.      Regards ....
