Never heard of this. I see it's a genetic test. I had the oncotype test instead. They both predict the re-occurrence of the tumor. But Thanks for the info. I feel like the better we are all informed - that's only a good thing.

I had a Mammaprint done. If you talk to your oncologist, he/she will tell you that, depending on the particular characteristics of your cancer, some of these tests are not going to work for you. In my case, the OncotypeDX was not viable, but the Mammaprint was.
