@katrina123 - I had MRI biopsy and yes you lie face down and the biopsy procedure can be uncomfortable. I like several others had extremely comforting assistants during the procedure that either held my hand or touched me with soothing music during the procedure. I had a previous Ultrasound needle core biopsy where they implanted a marker so there was no doubt where the MRI biopsy needed to be done. I can't for the life of me remember why I had two biopsies. But I know one was done at the start which determined I in fact had BC - determined it was Triple Negative; and the second was done after chemo, but before my bilateral. Not to give the impression that I'm tough, but I drove myself to both biopsy appointments and was provided an ice pack to place on the sight of the biopsy for my drive home. I'm just trying to impart that I was uncomfortable but not in pain and able to safely focus on my drive home from the appointment. I used that drive home to focus on my driving so I didn't focus on the what if's after the procedure.
