THE IMPORTANCE OF TUMOR GROWTH TYPES IN MAMMARY CANCER

Breast cancer (BR) is the most common form of malignant neoplasms among women worldwide, and its prevalence is constantly growing. With the development of modern radiation imaging technologies, such as magnetic resonance imaging (MRI), it plays a key role in preoperative diagnostics, which allows for the identification of multifocal and multicentric forms of breast cancer and a more accurate and timely assessment of their prevalence. Modern diagnostic methods allow for the determination of these parameters with high accuracy, however, existing prognostic models often do not sufficiently accurately account for their complex effect, which limits the possibilities of individualization of treatment and optimization of treatment strategies. Breast cancer is the most common form of malignant tumors among women worldwide, and its prevalence is constantly growing.  Modern technologies, such as magnetic resonance imaging (MRI), play an important role in preoperative diagnostics, which allows for the identification of multiple tumor foci and a more accurate and timely assessment of their spread. Multifocal (MF) and multicentric (MC) breast cancer are forms of the disease in which the presence of two or more tumor foci is noted. In MF, all foci are located in one quadrant of the mammary gland, while in MS, they are distributed into different quadrants. However, in the scientific literature, there is often no clear definition of the term "quadrant," which creates difficulties in standardizing approaches and research methodology.
