:Mammography is a form of imaging which uses low-dose x-ray systems. It is used to examine the breasts to help in the diagnosis of breast-related diseases like breast cancer, fibroadenomas, intraductal papillomas, fibrocystic breast conditions and cysts. There are two types of mammography: digital mammography and computer-aided detection. Digital mammography or full-field digital mammography is the type in wherein solid-state detectors replace the x-ray film. These detectors transforms the x-rays into electric signals. The electric signals created from the x-rays are then used for the production of the breast images. These images are seen on computer screens or printed on spacial mammograms.

The other type of mammography is the computer-aided detection or CAD. The CAD system is the type wherein digital mammographic images from a traditional or digital mammogram are used. A computer program is used to search for signs that might reveal the presence of cancer. The factors checked by the program includes density, mass and calcification.

Exposure to mammography is quite sensitive. Women who are about to have their monthly period are not recommended to undergo mammography because of the tenderness of their breasts during that time. A week after the monthly period is the suggested time for a mammography. Pregnant women are not allowed to be tested through mammography. Another thing to keep in mind before undergoing mammography is to avoid the application of deodorant, lotion or powder because they might appear as spots on the mammogram.
