What is a screening mammogram and why should I have one? A mammogram is an X-ray that can reveal both harmless and cancerous growths. A lump can be discovered two years before it can be felt. Finding a lump early increases a woman’s chance of surviving breast cancer and allows more treatment choices. Your breast will be placed on a special supporting platform. Firm compression will help position the breast and reduce breast thickness, resulting in a clearer "picture" of the breast tissue as well as reducing radiation dose. It may require additional views of the breast to better visualize the area of concern. (It may also include the use of other imaging modalities, such as ultrasonography). Spot compression and magnification views are intended to better define a possible mammographic abnormality. Mammography is the most advanced, effective, and accurate way to detect early breast cancer. However, about 10 percent of all breast cancers will not be identified by mammography alone – so monthly breast self exams, regular clinical exams, as well as routine screening mammograms, are recommended. Preparation Before your mammogram, please wash thoroughly and avoid the use of deodorant, powder, perfumes or ointments on your underarm areas or breasts. Because you will be asked to undress from the waist up, it is advisable for you to wear a two-piece outfit.
Try to schedule your mammogram following your period. This is when there will be the least tenderness. If you typically experience a lot of breast tenderness, reduce your caffeine consumption two weeks before your appointment. Examination Time Your exam will take approximately 20 to 30 minutes. We recommend that you allow an hour for your visit. After the radiologist reads the films, you and your physician will both receive the results.
Why would I need a diagnostic mammography exam instead of a screening exam? Diagnostic mammography is used to evaluate a patient with a specific breast problem or a questionable screening mammogram (mass, spontaneous discharge from the nipple, skin changes, an abnormal or questionable screening mammogram, etc.) or a history of breast cancer. The diagnostic mammogram should be correlated with physical findings and symptoms. Allow 45 - 60 minutes for a screening exam. It may require additional views of the breast to better visualize the area of concern. (It may also include the use of other imaging modalities, such as ultrasonography). Spot compression and magnification views are done to better define a possible mammographic abnormality.
Spot compression is used to optimize compression over a local area of concern and to displace overlying tissues away from the area of concern. Magnification is used to improve the visibility of the margins of a mass or to better see and characterize microcalcifications. The examination may be slightly uncomfortable, but should not be painful.
Written communication between the ordering physician and the mammography facility is very important. The radiologist will be present to discuss the results of your diagnostic mammogram with you. The radiologist may need to examine your breasts. A final report will be sent to your physician within two to three working days.
How will I receive the results? You will be given the results of your diagnostic mammogram or ultrasound at the conclusion of your examination by the radiologist. Your screening mammogram results will be mailed to you within two weeks.
Diagnostic Procedures The Saint Agnes Breast Center evaluates any detected abnormality by using a variety of imaging tests including ultrasound, breast biopsies, fine needle aspiration, cyst aspiration, core biopsy, galactogram, ductogram, needle localization and stereotactic core biopsy/mammotome breast biopsy.
