Mammography
Mammography is a specific type of imaging that uses a low-dose imagine system for examination of the breasts. The images of the breasts can be viewed on film at a view box or as soft copy on a digital mammography work station. Most medical experts agree that successful treatment of breast cancer often is linked to early diagnosis. Mammography plays a central part in early detection of breast cancers because it can show changes in the breast up to two years before a patient or physician can feel them

The National Cancer Institute (NCI) adds that women who have had breast cancer and those who are at increased risk due to a genetic history of breast cancer should seek expert medical advice about whether they should begin screening before age 40 and about the frequency of screening
Once an abnormality (abnormal mass, calcifications, distortions, etc.) is detected on the screening mammogram, a diagnostic mammographic examination is generally performed in order to obtain special views of the abnormality allowing a more detailed evaluation. This additional mammographic examination may include the use of special x-ray maneuvers and magnification of the abnormality in question as mentioned previously. Ductography is an examination that allows detailed evaluation of the breast milk duct and is indicated when there is a bloody nipple discharge or persistent discharge from a single duct in
the nipple.
There are approximately 15 to 20 major milk ducts that converge to the nipple. If the discharge is noted from multiple ducts or from both nipples, a ductogram is not indicated. The cause for multiduct discharge is usually related to a systemic cause (hormonal effect, pituitary disorder, etc.) and not cancerous. The examination is usually performed by inserting a small cannula (thin tube) directly inside the duct ostium in the nipple and contrast (x-ray dye) is injected to fill the duct. If the cannula cannot be placed through the ostium, the abnormal duct (which is usually enlarged) can frequently be filled percutaneously with ultrasound guidance
