BIRADS “0” After Diagnostic Mammograms

I don’t have health insurance other than at the VA right now. Before I lost the insurance, I had a screening mammogram done. It came back unclear as it nearly always does with these dense breasts. This time, though, I went to the VA for a diagnostic mammogram. They did many views and couldn’t make up their minds. The radiologist said he had to give me a BIRADS zero based on not being able to tell what was what. Basically, parts of the microcalcifications “piqued his interest.” Since my Mom- still alive age 78- had breast cancer three times, an initial case, a recurrence, and a third time separately, I’ve been getting mammograms since age 39, and now am 50, about the age my Mom was when she first got breast cancer. The radiologist says I need to get more past mammograms for him to review than just the ones I provided. The first private provider won’t release to me the past ones from across the country I provided to them before the screening mammogram, so I am starting over, trying to get past mammograms from across the country in Virginia (moved to California). He said after that, I can either get a mammogram assisted biopsy or wait 6 months and re-image. Last year, same breast, they saw enlarged lymph nodes and couldn’t find anything on ultrasound other than that, and I got a second opinion and that breast care center said get a 360 degree ultrasound. I did one and that shows nothing per the private provider. I paid them $190 for that to follow up from what the second opinion told me last year. I am trying to find another job with insurance and am just checking to see if anyone has ever heard of a radiologist not being able to tell if something is not benign through multiple views of diagnostic mammograms. He said no masses show up (matches what 360-degree automated ultrasound just said two months ago).
