Angular Margins on New Mass B-RAD 4

Hi everyone, 

I am 32 with a history of multiple fibroadenomas. The largest of my 4 was biopsied and it came back benign in 2020. Fast forward to present day, they have found a 5th hypo-echoic mass with angular margins and I need another biopsy. This one gives me a bad feeling because the margins are completely different than my other tumors. The radiologist marked it as a B-Rad 4 while my last biopsied mass was 4c. 

Has anyone with a history of fibroadenomas had a malignant parallel hypoechoic mass with angular margins?  

Hoping you get positive results Lizzy - keeping everything crossed x
