Mammogram question

I am one of the lucky ladies that had to start mammograms at 35 after a benign breast biopsy . Today , I went to a new screening center due to my insurance changing . They called me back for a second diagnostic mammogram and ultrasound . I do have breast tissue but have been really healthy since my breast biopsy two years ago . Has this happened to you as well? I am thinking it’s dense breast tissue and they just want to get a really good baseline . The little devil on my shoulder is telling my brain something different . If this has happened to you , What is your experience ? Thank you !!! 🧡
