[Prevention of breast cancer].

Analysis of 60 Russian and foreign publications demonstrated that the incidence of breast cancer and socio-biological characteristics of this disease necessitate improvement of methods for its prevention and treatment. Factors significantly increasing the probability of breast cancer are analyzed. Risk groups in need of thorough prophylactic examinations and treatment can be formed on the basis of these data. Some dyshormonal hyperplasias are considered as precancer. Active prophylactic measures, including surgery, are recommended for patients with such forms of mastopathy. There is a group of patients with 100% risk of breast cancer. Cancer can be prevented in them by prophylactic interventions, from resection of the mammary gland to subcutaneous mastectomy with plasty. Such strategy will have a positive impact on the incidence of breast cancer and the results of its treatment.
