Thank you. I am not with any major cancer clinic due to my insurance which is the reason I am participating in this site for patient education and support. I have found studies demonstrating promising results by initiating aromatase inhibitors prior to surgery if the time from diagnosis to surgery is extended however there was no mention of preserving options for Onco Type DX testing. Note that I was instructed by my surgeon that the AI's must be held 1 week prior to surgery due toan increase risk of clotting. Onco surgeons and Oncologist may not realize that biopsies generally do not provide adequate tissue, even collectively if more than one for Onco testing. I had four CA+ US-guided and 1+CA stereotactic biopsies at two different facilities (complicating matters more). I'm hoping to catch the attention of someone who may have been in the same bind or a Dr. who can recommend any viable way forward other than facing a future of doubt rather than peace of mind.
