Mammogram

(continued)

Results

A mammogram is an X-ray test of the breasts (mammary glands) that is used to screen for breast problems, such as a lump, and whether a lump is fluid-filled (a cyst) or a solid mass. Mammogram results are usually available within 10 days. It is not uncommon to be asked to return for another test so an additional view of an area in question can be obtained.

In the United States, facilities that perform mammograms send the results directly to your doctor's office and must send you a copy of the test results (written in language that is easily understood) within 30 days.

**Mammogram**
Normal:	Breast tissue looks normal. No unusual growths, lumps, or other types of abnormal tissue are seen. The glands that produce milk for breast-feeding and the tubes (ducts) through which milk flows appear normal.
Abnormal:	An abnormal growth, lump, or other type of tissue may be seen. A cancerous (malignant) or noncancerous (benign) tumor may be seen. One or more fluid-filled pockets (cysts) may be seen.
Abnormal:	Bits of calcium (calcifications) may be seen. Tiny calcifications (microcalcifications) often occur in areas where cells are growing very rapidly (such as in a cancerous tumor). Larger calcifications (macrocalcifications) are usually normal and noncancerous in women older than age 50.
Need more information:	A specific area needs to be looked at again. This is a very common result for many women and does not mean that the area is abnormal or cancerous.

Most abnormalities found during a mammogram are not breast cancer. But many women who have regular screening mammograms need more tests to investigate any abnormalities found during a mammogram. If an area of your breast tissue appears to be a concern during a mammogram, other tests may be done.

What Affects the Test

Reasons you may not be able to have the test or why the results may not be helpful include:

Deodorant, perfume, powders, or ointments applied to the breasts or under the arms before the test. They may interfere with the X-ray pictures.
Breast implants or scar tissue from previous breast surgery. This may make a mammogram harder to interpret.

A mammogram is not usually done if you are:

Pregnant, because the radiation could damage your developing baby (fetus). If a mammogram is absolutely necessary for diagnosing a problem, a lead apron will be placed over your abdomen to shield your baby from exposure to the X-rays.
Breast-feeding, because breasts that contain milk are very difficult to examine.
