Perceptions of risk factors for breast cancer and attitudes toward mammography among women who are current, ex- and non-smokers.

Understanding risk perceptions for breast cancer among women smokers is important because smokers tend to underutilize breast cancer screening. Perceptions of the relative importance of a variety of factors which may increase breast cancer risk and the benefits/barriers of mammography, were examined among women who were current (n = 185), ex- (n = 632) and never (n = 623) smokers. Participants were a subset of women taking part in a project to increase mammography utilization among women aged 50 and over. Current smokers, but not ex-smokers, were significantly less likely than never smokers to agree that health risk behaviors most frequently seen in smokers (e.g., smoking cigarettes, high-fat diet, low intake of fruits and vegetables, physical inactivity, drinking alcohol) may increase risk for breast cancer. Current smokers, but not ex-smokers, perceived more barriers and fewer benefits of mammography, than never smokers.
