Mammography, an
x-ray exam of the breasts, is currently the only exam approved by the U.S. Food and Drug
Administration (FDA) to screen for breast cancer and is
considered by physicians to be the gold standard in breast cancer
detection. Mammography can help detect approximately 85% of all breast cancers,
often before a lump can be felt. While many women over age 40 are familiar with the
benefits of yearly screening mammograms, the exam can
be uncomfortable and even painful for some women.
Unfortunately, some studies have shown
that the discomfort some women feel during a mammogram can deter them from receiving
future mammograms. This, in turn, can lead to delayed breast cancer diagnoses and
worse prognoses (expected outcomes) for some women.
Studies Pinpoint Causes of
Mammogram Discomfort
Several studies over the last 10 years
have isolated a number of factors that influence a womans comfort level during
mammography. These factors include:
Studies on discomfort/pain and
mammography reveal that many women experience discomfort during a mammogram; however, few
women find the exam extremely painful. In a study conducted by Duke University
Medical Center researchers, 93% of 125 women over the age 50 reported pain during the
mammogram exam. Most of the women describe the pain as low to moderate. In
another larger study, 52% of 1,800 women surveyed reported moderate to extreme discomfort
during mammography. Researchers have also found pain is a key factor in determining
whether women in breast cancer screening programs will return for future mammograms.
How Discomfort During
Mammography Can Be Minimized
By surveying women about their
experiences with mammograms, researchers offer suggestions on how to minimize discomfort
during mammography.
To alleviate much of the pain
associated with mammography, patients may wish to:
Breast
compression, which is necessary to flatten the breast so that the maximum amount of
tissue can be imaged and examined, is a major cause of fear and discomfort during
mammography.
Breast compression is necessary
during mammography in order to:
- Flatten the breast so there is less
tissue overlap for better visualization of anatomy and potential abnormalities. For
example, inadequate compression can lead to poor imaging of microcalcifications, tiny calcium deposits
that are often an early sign of breast cancer.
- Allow the use of a lower x-ray dose
since a thinner amount of breast tissue is being imaged
- Immobilize the breast in order to
eliminate image blurring caused by motion
- Reduce x-ray scatter which also leads to
image degradation
While breast compression can be
temporarily uncomfortable for some women, it should not cause significant pain. If a
woman experiences pain during a mammogram, she should notify the technologist immediately.
Patient-Controlled Breast
Compression
Some mammography facilities will allow
the patient to control the breast compression herself during mammography. This can
greatly reduce anxiety, making the woman feel more comfortable during the procedure, both
physically and emotionally. Women should feel free to ask the technologist about
controlling breast compression herself before the exam begins or when scheduling the
exam.
Researchers have found that a woman
often feels more comfortable during a mammogram with a courteous technologist who can
provide thoughtful answers to her questions. Knowledgeable technologists can also
help women with distraction techniques to take their minds off the exam. In a study
published in the February 2000 issue of the journal Radiology, researchers found
that factors associated with mammogram discomfort included the facility itself,
satisfaction with care, and the patients perception of the technologists
roughness.
If women are not satisfied with the
quality of care they receive at one facility, they should feel free to change
facilities. However, it is important that a patient obtain her original mammogram
films if she changes facilities so that future films may be compared to them.

minimizing pain during a mammogram.
Mammography Guidelines For
Women
Mammography is extremely important in
helping to detect breast cancer early. The earlier breast cancer is detected, the
greater the chance for minimally invasive treatment and survival.
The American Cancer Society, the
American Medical Association, the American College of Radiology, and other several
healthcare organizations and associations suggest that all women receive annual mammograms
beginning at age 40, in addition to yearly clinical
breast exams and monthly breast self-exams.
Women who are at high risk of breast cancer (such as those with a strong family
history of the disease or those who test positive for BRCA1
or BRCA2 gene mutations) should ask their physicians about beginning screening
mammograms at a younger age, as early as age 25 in some cases. All women under age
40 should also perform monthly breast self-exams and receive physician-performed clinical
breast exams at least every three years.
