Most Older Women Don't Get Mammograms
Study Shows Rate of Regular Screening Is Lower Than Previously Believed

June 20, 2006 -- Only about half of older white women and even fewer older black, Asian, and Hispanic women in the U.S. get regular mammograms -- a rate lower than had been thought, new research suggests.
Estimates based on self-reporting from women and widely relied upon by the medical community had placed the rate for having a mammogram every two years as high as 80% for women between the ages of 65 and 69.
But, regardless of their ethnic group, women 65 and older tend to overreport the number of mammograms they get, according to the study.
The new findings suggest the real figure for regular screenings is closer to 60% in this age group (65 to 69), and decreases with age over 69. For all women 65 and older, the rate is about 48%, according to the study, which relied upon MedicareMedicare data to estimate screening rates.
The disparity between self-reported screening rates and actual rates should serve as a wake-up call to doctors and policy makers, a study researcher tells WebMD.
"There may be a tendency to think that we are doing pretty well with screening, based on the self-reported figures," says Christopher R. Kagay, MD, of Massachusetts General Hospital. "These data remind us that we can probably do better."
Risk Increases With Age
A woman's breast cancerbreast cancer risk increases with age; three out of four breast cancers occur in women in their fifties and beyond.
But older women traditionally have not been screened as aggressively for breastcancercancer as younger women, even though the benefits are clear for those who are healthy enough to undergo treatment, says American Cancer Society spokeswoman Debbie Saslow.
"Women should continue to get regular mammograms for as long as they are in good health," she tells WebMD.
Checking the Numbers
In an effort to better understand mammogram usage among older women, Kagay and colleagues compared national Medicare Medicare data for 146,669 women to the self-reported data of mammogram usage from two large health surveillance databases. The data were collected between 1991 and 2001.
