They sat me down in a big chair for mine. The bang makes you jump a bit, but they warn you it’s coming. That’s the needle going in, then they will take the sample. Flush the line to collect sample, and put a chip in if required. It’s all numb and they don’t squish you as badly as a normal mammogram. It takes awhile to do it all. Just remember to breath. I felt I might move if I took normal breaths, but you don’t. I had to have about four taken, so it was a very lengthy process and I just sort of drifter off to my own world. There wasn’t any pain.
