How is a mammogram done?

You stand in front of a special x-ray machine. The person who takes the x-rays, called a radiologic technologist, places your breasts (one at a time) between two plastic plates. The plates press your breast to make it flat. You will feel pressure on your breast for a few seconds. It may cause you some discomfort; you might feel squeezed or pinched. But, the flatter your breast, the better the picture. Most often, two pictures are taken of each breast–one from the side and one from above. A screening mammogram takes about 15 minutes from start to finish.
