Hi Deb, I found a very good explanation about the reason for the Onco DX, and the theory behind it.
As I understand it, the test helps women and their doctors predict whether their type of cancer, even though you are node negative, is likely to reoccur. The tests that come back a high score are the types of breast cancer's where it would be advantagious to receive further treatment such as chemotherapy and/ or hormone therapy. You probably have an upcoming appointment with your oncologist to ask these questions. There is a website that is called Ajunctive Online or something similar. Your oncologist can plug in your type of cancer, staging, size, type and come up with your percentages. It will show your chances with chemotherapy and without. It was impressive and I went through chemotherapy and hormone therapy. If after you talk to your oncologist, and you still have questions, go for a second opinion. I would also advise you to bring along a friend, spouse, other family member who can take notes. You will probably need some help processing all the information. You will do fine. It's a big journey but your have a whole bunch of women who have been there.... done that. Healing hugs, Sharon
