The paper discusses the 5-year experience of operation of cancer control service provided at a hospital department with a capacity of 50 beds as well as the results of two out-patient mammological screenings conducted by the Dispensary staff. Coordination of this work yielded a unified approach to the diagnosis and treatment of precancer and cancer of the breast. It also ensured continuity in application of procedures of therapy and prophylactic medical examination in the entire cancer control service of the Region. As a result, early diagnoses of breast cancer have become more reliable and treatment of precancerous lesions has improved.
