HI There, Thanks First For The Possibility To Ask You

HI there, thanks first for the possibility to ask you questions online ! appreciate ! I got a mammography 2 weeks ago and the findings are : scattered fibroglangular densities and an irregular mass with associated fine pleomorphic calcifications in the left breast .The radiologist impression : BI-RADS Category 4C. I had a biopsy guided through ultrasound and the results are benign but the concern is still there ...I'm going to have an MRI soon and a blood test for Vitamina D and Iodine and after that I'm going to have a stereotactic biopsy . ...My question is did you ever hear about this kind of diagnostic to be benign ?!
