Currently, all breast cancers. Should be tested for expression, or detectable effect, of the estrogen receptor (ER), progesterone receptor (PR) and HER2/neu proteins. These tests are usually done by immunohistochemistry and are presented in a pathologist's report. The profile of expression of a given tumor helps predict its prognosis. Or outlook, and helps an oncologist. Choose the most appropriate treatment. More genes and/or proteins may be tested in the future. June 6, 2009 at 9:33 AM.
