As a Breast Imaging Center of Excellence in Michigan, Beaumont offers patients leading edge mammography services.
Beaumont recommends screening mammography for women age 40 and older. Talk with your Beaumont doctor about how often you should have a mammogram. The American Cancer Society recommends that women use a facility, such as Beaumont Hospital that specializes in mammograms.
Beaumont has reached the American College of Radiology (SCR) Gold Standard for Mammography. Reaching the Gold Standard means our facilities have demonstrated a strong commitment to image quality and safety.
Beaumont was the first in Michigan to provide MRI, ultrasound and mammography at their Women's Breast Imaging Centers.
Beaumont Cancer Institute offers:
- a fully accredited diagnostic radiology program performing thousands of digitized mammograms each year
- the first computer-aided diagnosis for all screening and mammography, and the first MRI-guided breast biopsies in Michigan
- a high-risk evaluation clinic with access to advanced breast MRI technology, clinical breast exams, annual imaging, genetic and risk-reduction counseling services, and the latest diagnostic protocols
Mammography or not?
The findings in the recently reported Canadian study differ from those of most other clinical trials on mammography. They also differ from the consensus of most experts including the U.S. Preventive Services Task Force, which has estimated breast cancer screening reduces the relative risk of death in women aged 40 to 59 by about 15 percent.
At this time, the findings from the Canadian trials are not sufficient to change the recommendation that most healthy women get regular mammograms starting at age 40.
What is a mammogram?
A mammogram is a safe, low-dose x-ray examination of the breast. It is currently the most effective method of detecting breast cancer in its earliest, most treatable stages. It is used to detect and diagnose breast disease in women who either have breast problems such as a lump, pain, or nipple discharge, as well as for women who have no breast complaints.
Mammography cannot prove that an abnormal area is cancer, but if it raises a significant suspicion of cancer, tissue will be removed for a biopsy. Tissue may be removed by needle or open surgical biopsy and examined under a microscope to determine if it is cancer.
Mammography has been used for about 30 years, and in the past 15 years technical advancements have greatly improved both the technique and results. Today, dedicated equipment, used only for breast x-rays, produces studies that are high in quality but low in radiation dose. Radiation risks are considered to be negligible.
What are the different types of mammograms?
According to the National Cancer Institute:
- screening mammogram A screening mammogram is an x-ray of the breast used to detect breast changes in women who have no signs of breast cancer. It usually involves two x-rays of each breast. Using a mammogram, it is possible to detect a tumor that cannot be felt.
- diagnostic mammogram A diagnostic mammogram is an x-ray of the breast used to diagnose unusual breast changes, such as: a lump, pain, nipple thickening or discharge, or a change in breast size or shape. A diagnostic mammogram is also used to evaluate abnormalities detected on a screening mammogram. It is a basic medical tool and is appropriate in the workup of breast changes, regardless of a woman's age.
The recent development of digital mammography technology shows promise for improved breast imaging. Digital mammography provides electronic images of the breasts that can be enhanced by computer technology, stored on computers, and even transmitted electronically in situations where remote access to the mammogram is required.
How is mammography performed?
X-rays of the breast are different than those used than for other parts of the body. The breast x-ray does not penetrate tissue as easily as the x-ray used for routine x-rays of other parts of the body. The breast is compressed by the mammogram equipment to spread the tissue apart. This allows for a lower dose of radiation. Compression of the breast may cause temporary discomfort, but is necessary to produce a good mammogram. The compression only lasts for a few seconds for each image of the breast. A breast health nurse or x-ray technologist usually takes the x-rays, but the resulting films are read and interpreted by a radiologist, who reports the results to your physician.
What conditions does a mammogram show?
- Calcifications, tiny mineral deposits within the breast tissue. There are two categories of calcifications:
- macrocalcifications - coarse calcium deposits that usually indicate degenerative changes in the breasts, such as:
- aging of the breast arteries
- old injuries
- microcalcifications - tiny (less than 1/50 of an inch) specks of calcium. When many microcalcifications are seen in one area, they are referred to as a cluster.
- Masses, which may occur with or without associated calcifications, and may be due to different causes, including:
- cyst - a noncancerous collection of fluid in the breast. It cannot be diagnosed by physical exam alone or by mammography alone. Either breast ultrasound or aspiration with a needle is required. If a mass is not a cyst, then further imaging may be obtained.
- benign breast conditions - masses can be monitored with periodic mammography, but others may require immediate or delayed biopsy.
- Breast cancer
Who should have a mammogram?
The guidelines vary regarding when and how often to have a mammogram and a breast screening. These guidelines depend on your personal history, your risk for developing breast cancer, your family history, and your age, among other factors. However, doctors usually recommend that women who have a normal risk and no personal history of breast cancer begin having screening mammograms at around age 40. Women who are at high risk should talk to their doctors about when to start and how often to have mammograms. We recommend that everyone start having annual breast screenings and mammograms by age 40 – regardless of risk – and earlier if you’re at higher risk.
Here are some typical reasons women schedule mammograms:
Having your regularly scheduled breast exams and mammograms is the best way to detect breast cancer early – before it spreads to other parts of the body. The earlier you detect breast cancer, the greater your odds are of surviving it. Depending on your risk factors and the density of your breasts, your doctor may recommend additional screening tests, such as an MRI or an ultrasound.
Consult your physician regarding the screening guidelines that are appropriate for you.
