Awareness and Misconceptions of Breast Cancer Risk Factors Among Laypersons and Physicians

Abstract : Background Primary prevention of cancer relies on awareness of and consequent identification of risk factors. We investigated knowledge of breast cancer risk factors not only among laywomen but also among female physicians. Methods The EDIFICE 4 nationwide observational survey was conducted by phone interviews of a representative female population (737 laywomen and 105 female physicians) aged 40-75 years, using the quotamethod. This analysis focuses on spontaneous replies to the question ``In your opinion, what are the five main risk factors that increase the risk of breast cancer?''. Results Heredity/Family history of breast cancer was the most widely recognized risk factor in both study populations (98.1% physicians vs. 54.2% laywomen; P <= 0.01). Smoking (19.0 and 17.5%) and alcohol consumption (3.8 and 5.5%) were among the lifestyle risk factors that were cited by similar proportions of physicians and laywomen, respectively. Other established risk factors were however very rarely cited by either physicians or laywomen, e.g., Exposure tomedical radiation (4.8 vs. 0.4%, respectively; P <= 0.05) or not cited at all, i. e., Benign mastopathy and Personal history of breast cancer. Conclusion This survey highlights a number of misconceptions relating to behavioral risk factors for breast cancer, including the relative impact of alcohol and tobacco consumption and the importance of menopausal status. The limited awareness of the risk related to Exposure to medical radiation, Benign mastopathy, or Personal history raises concern regarding compliance with national screening recommendations.
