[Synchronous cancer of the breasts].

Observation on 16 patients with synchronous cancer of mammary glands are reported. This group comprised patients in whom tumors developed either simultaneously or with a 6-month interval. Synchronous cancer was more frequently observed in patients in the period of active menstrual-ovarian function (an average age--40.5 years). Eleven of these patients survived for 3 years and longer; 5 of them survived without any recurrence and metastases within the terms from 3 to 16 years. The use of the complex therapy encourages the hope of improving remote results.
