65+: Breast cancer screening--mammography
Definition: Percentage of women aged 65 and over who had mammograms within the past two years, two- or three-year average
Notes: The data are from Behavioral Risk Factor Surveillance Survey (BRFSS). Respondents were asked the questions: "A mammogram is an X-ray of each breast to look for breast cancer. Have you ever had a mammogram?" and "How long has it been since you had your last mammogram?" These questions were asked every even year of the survey, although some states chose to include them in other years. Percentage is a 2- or 3-year average, which helps to reduce the year-to-year fluctuation due to small numbers. Percentage is reported under the year at the midpoint of the 3-year period; e.g., the average of and 2000 and 2002 was reported under 2001. National data is the median of the 50 states and the District of Columbia.
