This whole mount shows an overall view of changes in the breast which include: 1. dense and hardening of the supportive, fibrous tissue (broad pink areas), 2. cystic changes (white, clear areas) which will enlarge with accumulations of fluid. Larger cysts on mammograms often look like masses but with ultrasound examination of the breast, the difference between cysts and masses (tumors) is easier to distinguish. Small collections of glands represent early adenosis.
