Oncotype DX is a special genetic test. The lab where your specimen is sends a piece of the tumor to a place in California where they conduct several genetic tests on it to determine more of its makeup, if chemo. is needed, reoccurance rate, etc. The score ranges from 0-100 and depending on the number your onc. can tell you if chemo. is needed or not. Ask if they have a phamlet on it as my oncology clinic did and it was very useful. I believe your tumor has to be low grade and not in the lymph nodes to fit their patterns for testing as I recall. You can google Oncotype DX test and should get some info. that way, too.
