The objective of this study was to investigate, in a female population-based sample, specific demographic and psychosocial predictors of perception of risk for female breast cancer. The study was a cross-sectional survey of 7135 healthy women ranging from 15 to 85 years. A questionnaire assessed the perceived risk for breast cancer in 6 German centers. Specified awareness was personal knowledge in relation to breast cancer incidence, risk factors, perception, and level of concern. An awareness score was defined and related to values of several risk factors. Generally, 78.1% of women were aware of breast cancer. However, only one-third (31.2%) of women estimated the incidence of breast cancer correctly; 52% recognized age, 33.9% recognized hormonal contraceptives, and 34.1% recognized hormonal replacement therapy as factors of breast cancer risk. The most frequent specified sources of information were gynecologists (48.4%). The awareness score of women informed by gynecologists was significantly better compared to women informed by other healthcare professionals. However, a statistically significant improvement of the awareness score was reached for women with a higher educational level, information seeking by TV, radio, printed sources, medical books and healthcare flyers. Recommendations for improvement of cancer prevention programs include targeting comprehension regarding the lifetime risk of breast cancer, age as a risk factor, survival from breast cancer and hormonal factors. According to these results, there is an urgent need to separately address the perceptions of women, depending on age, social status and educational level.
