Since 2003, the percentage of US women receiving mammography screening for the detection of breast cancer has declined—the first drop seen since the technology came into use (Breen N et al. Cancer. 2007;109:2405-2409).
In the study, researchers at the National Cancer Institute reviewed data collected by the National Health Interview Survey from 1987 to 2005 and then used 2000 and 2005 data to determine recent trends. They found that mammography screening rates for women older than 40 years increased from 39% to 70% between 1987 and 2000. But rates flattened out between 2000 and 2003. The rates began falling in 2003 and continued to decline through 2005 to 66%. The biggest drop-off, 6.8 percentage points from 78.6% to 71.8%, was found among women aged 50 to 64 years.
