Mammo. The tech will ask you to stand facing the mammo machine, and place one breast at a time on a flat surface.A flat compression paddle will gently be lowered to compress your breast. Compression spreads out the breast tissue and eliminates motion.The compression may be uncomfortable,but shouldn't hurt. Compression usually lasts no more than a few seconds. 2 views of each breast are obtained.
Pressure. The breasts are placed individually between two surfaces while images are being taken. I have never experienced pain during a mammogram. But some women experience discomfort as their breast is smushed.
