In brief: Receptor Status

The er positive refers to the receptor status of the breast cancer.
This means that the tumor has receptors to estrogen and that anti-estrogen therapy can be used to slow the growth of the tumor. Her2 is a another receptor that is a target of a chemotherapeutic agent called herceptin (trastuzumab).

In brief: See below

Estrogen receptor (er) is measured to determine whether a tumor is sensitive to hormonal manipulation (things like tamoxifem, arimidex, or removal of ovaries - depending on your age and other factors.
Er+ tumors have better prognosis. In general her2 + tumors have a worse prognosis, but these tumors may respond to Herceptin (trastuzumab) or similar drugs.
