Do Cancer Survivors Get Mammograms?
Researchers Find Breast Cancer Survivors Aren't Always Getting Screened
April 24, 2006 -- Annual mammograms are strongly recommended for women who have been treated for breast cancer, but surprising new research suggests that as many as two-thirds of survivors are not getting them.
Screening rates among survivors in the study were high early on. Four out of five had a mammogram in the first year after treatment. But mammography screening declined over time.
By year five, only a third of the women had had an annual mammogram every year since cancer treatment ended.
Approximately 2.3 million women in the U.S. have been treated for breast cancer.
"As time passes, women may think less and less about their breast cancer risk or they may be dealing with other illnesses," University of Massachusetts family medicine specialist Chyke Doubeni, MD, MPH, tells WebMD. "But it may be that former patients aren't really sure what they should be doing."
Why It Matters
Women who have been treated for cancer in one breast have three times the normal risk of developing a second primary cancer in the opposite breast.
It is clear that mammography screening is underutilized in the general population, but less is known about utilization rates among breast cancer survivors.
To address this issue, Doubeni and colleagues reviewed mammography screening records for 797 women who had been treated for breast cancer and whose screenings were covered by health insurance.
All of the women in the study were 55 or older at the beginning of the study, and their average age was just under 70.
In the first year following treatment, 80% of the women had a mammogram, but by the fifth year just 63% of the women were screened. Only 33% of the women were screened every year for five years.
Since all the women in the study had health care, cost was not believed to be a factor in declining utilization.
While age and the possible emergence of other health issues may have played a role, Doubeni says it also seems likely that many of these women fell through the cracks with regard to follow- up.
Women who regularly saw their primary care physician or gynecologist were more likely to get screened than women who did not.
