What is Mammography?
Mammography is a specific type of imaging that uses a low-dose
x-ray system to examine breasts. A mammography exam, called a
mammogram, is used to aid in the early detection and diagnosis of
breast diseases in women.
An x-ray (radiograph) is a noninvasive medical test that helps
physicians diagnose and treat medical conditions. Imaging with
x-rays involves exposing a part of the body to a small dose of
ionizing radiation to produce pictures of the inside of the body.
X-rays are the oldest and most frequently used form of medical
imaging.
The Breast Health Center offers digital mammography, the most
advance breast imaging technology available today.
Digital mammography, also called
full-field digital mammography (FFDM), is a mammography system in
which the x-ray film is replaced by solid-state detectors that
convert x-rays into electrical signals. These detectors are similar
to those found in digital cameras. The electrical signals are used
to produce images of the breast that can be seen on a computer
screen or printed on special film similar to conventional
mammograms. From the patient's point of view, having a digital
mammogram is essentially the same as having a conventional film
mammogram.
How to Prepare for the Exam
Before scheduling a mammogram, the American Cancer Society (ACS)
and other specialty organizations recommend that you discuss any
new findings or problems in your breasts with your doctor. In
addition, inform your doctor of any prior surgeries, hormone use,
and family or personal history of breast cancer.
Do not schedule your mammogram for the week before your period
if your breasts are usually tender during this time. The best time
for a mammogram is one week following your period. Always inform
your doctor or x-ray technologist if there is any possibility that
you are pregnant.
The ACS also recommends you:
- Do not wear deodorant, talcum powder or lotion under your arms
or on your breasts on the day of the exam. These can appear on the
mammogram as calcium spots.
- Describe any breast symptoms or problems to the technologist
performing the exam.
- If possible, obtain prior mammograms and make them available to
the radiologist at the time of the current exam.
- Ask when your results will be available; do not assume the
results are normal if you do not hear from your doctor or the
mammography facility.
