Mammograms
Mammography uses low-dose x-rays to make a picture of breast tissue. The picture of the breast tissue is called a mammogram.
Mammography is a screening tool for breast cancer. It helps radiologists see the normal and abnormal structures in the breasts, including cysts, masses, and calcifications, which are deposits of calcium. Large deposits are not usually cancerous, but small specks of calcium, called microcalcifications, are sometimes found in areas where cells divide rapidly—as cancer cells do.
What to Expect
You do not need to do anything special for your mammogram, but you should not use deodorant or talcum powder on the day of your exam. You will need to remove your top and bra, and any jewelry in the area.
The technician will gently place your breast between the special plates in the mammography machine. The plates compress the breast for a clearer image of the breast tissue, making an x-ray easier to read. The technician will take two pictures of each breast: one looking down at the breast and the other a side view. The doctor may ask for additional images to examine a specific spot more closely, or if you have breast implants.
Results
A radiologist trained in reading mammograms will review your images, and will either discuss them with you or let your physician know the results.
Screening Recommendations
The American Cancer Society recommends that women age 40 and older have a mammogram each year. The National Cancer Institute recommends having one every one or two years.
If you are at risk for developing breast cancer, your doctor may suggest more frequent mammograms.
