Lactation mastitis remains one of the most common inflammatory pathologies of the postpartum period, significantly affecting the mother's health and the duration of breastfeeding. Despite the development of modern diagnostic and treatment methods, the frequency of mastitis among breastfeeding women remains high - from 5 to 12%, and in some regions reaches 20%. This work presents clinical observations of 630 patients with various forms of lactation mastitis, analyzes risk factors, the timing of the inflammatory process, clinical features, and treatment outcomes. Special attention is paid to modern diagnostic criteria, including the role of ultrasound in the early detection of abscessing forms. Modern approaches to therapy according to international recommendations (ABM Clinical Protocol#36, ACOG, CDC, RCOG) are summarized, emphasizing the need to preserve breastfeeding and apply minimally invasive treatment methods. The analysis confirmed the key role of early application to the chest, prevention of nipple injuries, and correction of anemia in reducing the frequency of mastitis.
