Hi Daisy_01, DearB and Harley B, I too wasn't diagnosed through a mammogram. I had a cyst that was aspirated and then while having an ultrasound "Oh Whats That:? came the comment. Out the door and in with another doctor who also said.. "hmmm not sure what this is" better biopsy. turned out it was idc 11mm with some dcis. No Lump palpable by any of the medical staff. It was undetectable on mammogram. So I have discussed with my surgical team after lumpectomy and radiation what will be done for follow-up scans. I have a strong preference for no mammogram just an ultrasound and will continue to discuss this with them. Self exams are a given. So will wait and see. Nothing is 100 percent guaranteed. Such dilemmas we face on this path.
