Lispy, I was diagnosed with mammogram/ultrasound (it didn't show up at all on the mammogram) followed by 2 core biopsies.
Before chemo my Oncologist ordered CT scans of head, chest, abdomen and pelvis. I also had a nuclear bone scan before starting chemo.
I asked about an MRI as a possible follow-up but neither he nor my GP liked the idea - too much radiation and too many possible false positives which would cause anxiety.
I will only be given an MRI if I exhibit symptoms. (I am in Qld too, on the Gold Coast.)
