Yes, I also had an ultrasound guided needle biopsy. Mine was also painless and stress free. I was lying comfortably on my back and the radiologist did the biopsy. My malignant tumor was only 7 mm, buried deep and she was able to hit the target using that procedure. It was 10 years ago so I don't remember how long it took. An hour? They also biopsied another nodule at the same time that turned out to be benign. Very kind and gentle radiologist and assistant. Blessings, Zebra
