A mammogram is an x-ray picture of the breast. When a woman, her doctor or nurse discovers something abnormal in the breast, such as a lump, her doctor will schedule a diagnostic mammogram . It is also used to further evaluate abnormalities that are detected during a screening mammogram. Before the x-ray is taken, two plastic plates compress the breasts to give a clear view of all breast tissue. A radiologist, specially trained to interpret and analyze mammogram x-rays, will examine the films for masses, calcifications or other abnormalities that might indicate breast cancer.
Most states now require health insurance to cover part or all of a screening mammogram's cost.
There are also many low-cost or free ways to get a mammogram. Test results are usually available in one to two weeks. Your doctor or radiologist will talk to you about your x-rays. The radiologist may also compare your x-rays to films from any previous mammograms you have had. If an abnormality is detected, your doctor will talk to you about any other tests you may need for further diagnosis, as well as the possibility of a breast biopsy.
