Cancer is a broad type of disease in which cells grow abnormally and uncontrollably anywhere in the body and can spread to other areas. Cancer is the second leading cause of death in the world. According to age-standardized incidence rates of cancer types in the world and in our country, breast cancer is the most common cancer in women (World Health Organization, 2020). While breast cancer ranks first in the world in age-standardized mortality rates of cancer types in women, it ranks second after lung cancer in our country (World Health Organization, 2020). Public health approach is important in the fight against cancer, which is within the scope of non-communicable diseases. In this context, primary and secondary prevention is very important. Within the scope of secondary prevention, early diagnosis of breast cancer is of great importance. Early diagnosis is screening in cases without any symptoms and diagnosis in cases with early symptoms. In early diagnosis of breast cancer, mammography obtained with X-rays as an imaging method is at the forefront. With the increasing practical use of mammography, the Breast Imaging-Reporting and Data System (BI-RADS) was first introduced in 1993. It provided a structured report template for imaging and an assessment category with patient management advice.
