Perceptions of breast cancer risk and screening effectiveness in women younger than 50 years of age.
The purpose of this study was to determine how women 40-50 years of age perceive their risk of breast cancer and the effectiveness of screening and how these perceptions compare with estimates derived from epidemiologic studies of breast cancer incidence and randomized clinical trials of screening.
We mailed a questionnaire to 200 women, identified through the computerized medical records of Dartmouth-Hitchcock Medical Center, who were between 40 and 50 years of age and had no history of breast cancer.
Each woman was asked about her risk factors for breast cancer and asked to estimate her probabilities of developing breast cancer and dying of it within 10 years, with and without screening.
The women's answers were compared with individual probabilities derived from the Gail et al. model, age-specific probabilities of developing and dying of breast cancer in the United States, and the results of randomized clinical trials of screening.
The mailed questionnaire was completed and returned by 145 (73%) of the 200 women.
Respondents overestimated their probability of dying of breast cancer within 10 years by more than 20-fold (median, 22.3 ; interquartile range, 11.1-74.2).
These findings suggest that many women younger than 50 years of age substantially overestimate their breast cancer risk and the effectiveness of screening. [J Natl Cancer Inst 87 : 720-731,1995].
