Hi

After my first screening mammogram I was called for a diagnostic mammogram and ultrasound due to a “mass” at the very back of my breast.   The mass didn’t show up on the ultrasound but another cluster of cysts were spotted, these didn’t show on the mammogram.   A biopsy was taken.   I was told I have busy breasts.    I had a second biopsy via a mammogram machine on the mass at the back.    Worried that two biopsies indicate a problem.   Has anyone experienced anything similar? 

Thank you x
