I've been called back (because of "dense breasts") and had 3 biopsies. The first time I was called back for a second look was in 2018. There was calcification. A biopsy was done---even though I was not told in advance that they would be plunging a 3 foot long needle into my right breast---and it was found to be benign. (I've always wondered if I should have refused to go along with their plan to do this solid core stereotactic biopsy without informing me that that was "the plan" in advance. A passing radiologist said I could have waited and come back in 6 months and monitored the calcification that way, and I wonder(ed) if digging around in there caused the tumor to form that was found on Pearl Harbor Day in 2021. Since that fine needle biopsy, I think it was, which confirmed an 11 mm, tumor, I've had a lumpectomy and been through the mill with adjuvant therapy and 33 radiation sessions. I was subjected to a third diagnostic mammogram on the one-year anniversary of my surgery (1/27/2022) when I paid for an ultrasound (HerScan) out of pocket and flunked it. The 2018 biopsy was so painful that I held out for gathering all of my mammograms and using the comparison to determine if I had yet another tumor, one year later. This was quite an undertaking, involving hospitals in Illinois, Iowa and Texas, but I had had them faithfully at yearly intervals and when they arrived no new tumors were seen. I have read up on calcification and it seems that if it begins to show up in a line, it is worse than random spots seen. I will not willingly subject myself to a stereotactic biopsy if I can avoid it by waiting for them to assemble all of my mammograms through the years. It was very painful and took months to heal, despite the messaging about what a piece of cake it is. The one that found the tumor was done with a needle that had a curly tail like a pig's tail and was significantly less painful (Otherwise, I might have refused to go through with it on Dec. 7, 2021).
