Mammogram

X-Ray, Breast (Mammography)

Results

A mammogram is an X-ray test of the breasts (mammary glands) 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.

The results of a screening mammogram are sent directly to your family doctor's office and—in some provinces—will also be sent directly to you. If the mammogram is done to diagnose a problem, the results will be sent to your family doctor, and he or she will discuss the results with you. If you have a mammogram that was not ordered by your doctor, a copy of the results will be sent to you.

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 non-cancerous (benign) tumour may be seen. One or more fluid-filled pockets (cysts) may be seen.
	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 tumour). Larger calcifications (macrocalcifications) are usually normal and non-cancerous in women over the age of 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. However, many women who have regular screening mammograms need additional 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.
