Benign breast tumors and risk factors for their development

Abstract

Introduction. Benign mammary gland tumors constitute a group of heterogeneous diseases with a complex clinical and morphological structure that complicates timely diagnosis and terminological designation of pathological processes. They are of great interest because of their possible background for oncologic pathology. The most widespread disease is mastopathy, its occurrence rate in the population reaches 40%. The incidence of mastopathies increases by the age of 45 years, and then tends to decrease in the pre- and postmenopausal periods. The purpose of the review was to evaluate and analyze the literature data on the presented problem in recent years. Materials and methods. Publications of domestic and foreign authors on benign breast neoplasms and risk factors of this pathology over the past 20 years have been included in the article. Literature search was performed in the systems Scopus, Web of Science, PubMed, Elibrary. Results and discussion. Etiopathogenetic factors in patients with benign mammary gland tumors play a paramount role, substantiating the necessity of prognostication and prevention of the disease. Risk factors for these diseases include hereditary, hormonal, neuropsychological, reproductive data, age, lactation, inflammation, trauma, smoking, and others. Conclusion. The current dynamic of increasing the incidence of benign mammary tumors has been noted, but no specific risk factors for this group of diseases have been identified, as they are multifactorial, associated with genetic causes, somatic health data, and environmental influences. Not all women are equally at risk of developing breast diseases, the reasons characterizing the individual propensity for this pathology have been identified. The risk factors do not cause the development of the disease, but considerably increase its probability. The study of predisposing risk factors for the development of tumor processes in the mammary glands in order to diagnose them early gives an opportunity to improve the results and prognosis of treatment.
