Purpose of the study: to analyze the methods available in the literature for the prevention of postmastectomy lymphorrhea, systematize the data obtained, and substantiate the relevance of the search for new methods for the prevention of lymphorrhea.A search was conducted for published scientific studies in the Pubmed and Elibrary databases using the keywords: «лимфаденэктомия», «лимфорея», «рак молочной железы», “lymphadenectomy”, “lymphorrhea”, “breast cancer”. Using the given keywords, more than 500 scientific papers were found.Most of the currently existing methods for preventing postmastectomy lymphorrhea are systematized into groups. The disadvantages of known methods have been studied, which boil down mainly to unjustified anatomical destruction, economic unprofitability or ineffectiveness of these methods.Thus, the search for a new method of preventing lymphorrhea is still relevant.
