Breast cancer is the most common malignant disease in women. It represents a major public health problem that affects women of all age groups. Statistically, young women diagnosed with breast cancer have a higher mortality rate than older women. Self-examination is the cheapest and simplest preventive measure that women should perform at least once a month. In addition to self-examination, women should regularly go for clinical examinations and mammograms. Women over 50 years of age belong to the risk group, but recently, younger women are also more often affected. The cause of breast cancer has not been fully elucidated, but long-term research singles out risk factors that certainly influence its development. These are lifestyle, hormonal status, anthropometric characteristics, radiation and genetic susceptibility. The aim of the work is to examine the awareness of the general population, ie women aged 20-60, about breast cancer. The main hypothesis of the research is to determine whether there is a significant difference in the general population's awareness of breast cancer prevention and disease with regard to sociodemographic data. The relationship between being informed about breast cancer, the tendency to self-examination and the fear of discovering cancer was also examined. For the purpose of the research, a validated anonymous questionnaire was used. 178 female respondents aged 20-60 participated in the research. The results were processed using appropriate statistical methods and presented in a table. The results of the work showed that there is no statistically significant difference between the place of residence of the participants in terms of information about breast cancer prevention and disease. According to the results of the difference according to the level of education of the participants in information about the prevention and disease of breast cancer, it was observed that there is a statistically significant difference between the variable that when breast cancer and/or ovarian cancer occurs in the family, the risk of developing breast cancer increases with regard to the level of education of the participants
