Thank you for your reply. I hope I did not upset you with my question. I do not know whether either you or I should be scared...all I know is that I cannot seem to get this out of my mind. I do know a lot of doctors do not use tumor markers....there are blood tests for a few for breast cancer, but what I hear about most after starting treatment is the ca 27.29. My best friend had BC and her doctor told her he did not use tumor markers because they are not dependable and only upset the patient. People like you and I just do not know. The first time I had BC, I saw the oncologist every 4 months for 5 years. Then he said I did not have to see him anymore. I did not have chemo, but did have radiation both times. I am thinking I should not be panicking...and neither should you after reading my narrative. We are all very different and all the doctors do different stuff. I feel great and have no complaints...even taking anastrozole, so am really devastated about this. I am not so worried about the test...more so that I will get lymphedema from the IV. I think if you are having strange stuff happening with your breast, you may want to go to your doctor and have it checked out. Waiting until September will only give you more time to think about it and to worry. Let’s hope other people respond to this topic so we can get more information.
