Breast cancer is the most common disease in women. It represents a major public health problem and affects all age groups of women. There is a statistically significant increase in the mortality of young women diagnosed with breast cancer compared to older adults.Self-help is the simplest prevention method that women should spend at least once a month. It is very important at which stage the cancer is discovered because earlier detection gives a greater possibility of cure.The mammography is also a self-evident method of early detection. The best treatment efficacy provides a combination of surgical treatment, systemic treatment and radiation. Some of the risk factors are age, inheritance, lifestyle, nutrition, race, socioeconomic status, reproductive status and very important anthropometric features. A study was conducted to examine and demonstrate the level of knowledge of women about breast self-examination, whether they know what factors increase the risk of breast cancer, and how often they perform a complete check-up at the doctor. 750 women participated in the study. The survey was conducted online and participation in the survey was completely anonymous and voluntary.A sixteen-questionnaire questionnaire, constructed for the purposes of this research, was used to collect sociodemographic data and examine the cognitive, emotional, and action components of attitudes toward breast tumors. The data were processed in the SPSS (Statistics for Windows) statistical program. The results show that more than three-quarters of women are familiar with the correct way of self-examination, more than half are afraid of breast cancer, more than three-quarters of women agree that cancer within the family increases fears of their own disease. Then, more than half of women think they would pay more attention to their own health if their loved one became ill.Less than one in seven participants identified five or more risk factors accurately, indicating that women need to be further educated on the risk factors contributing to breast cancer. Half of the participants responded that they would begin a monthly self-examination routine if given the correct self-examination instructions. More than half of the participants stated that they had never undergone a full medical examination. About the impact of media campaigns on thinking about their own health, more than half of the participants said that they felt that media campaigns encouraged them to think about their own health. The research findings highlight the usefulness of media campaigns and national prevention programs in the early detection of breast cancer.
