ABSTRACT

Indications for puncture or excision biopsy were significantly higher in the study group (7.5%) as compared with control (3.5%) (p < 0.01) in a randomized prospective controlled trial of a comprehensive breast cancer screening (123,748) carried out in the framework of a self-examination education program. In the self-examination group, detection rates were higher both for benign (1.1%) and malignant (0.85%) tumors than in control (0.5% and 0.69%, respectively) (p < 0.05). Early stage (T1NOMO, Tis) distribution difference in the study group and controls was insignificant--23 and 17.6%, respectively. Compliance with the program requirements including monthly or bimonthly self-examination was followed by higher 15-year survival rates (53.2%) in 70-75% as compared with controls(45.8%) (p = 0.05105) yet it did not affect mortality.
