How would a normal mammography xray look?

Variable: Amounts of fat and gland tissue exist in each patient but usually the appearance is symmetrical. No masses, asymmetry, concerning calcifications, or skin thickening.

Varies tremendously.: Glandular tissue (appears white on a mammogram) varies tremendously among women. Many women have very glandular (dense, white) mammograms which can obscure cancers which are also white. However, many cancers have calcifications in them which show up as white dots and are easily seen even in "dense" breasts. Calcifications in the breast are common but must be distinguished from cancer.

Normal Mammo: Difficult to describe because it is a visual interpretation and there is a very wide range of normal appearances.
