[Preventive medicine for prostatic cancer].
We are promoting a project of preventive medicine for prostatic diseases. As the primary prevention (prevention of morbidity), high risk groups of prostatic cancer were determined by a case-control study. The results are being introduced thoroughly to the people. As the secondary prevention (prevention of development), an original mass screening system using a special mobile unit with two sets of transrectal ultrasonic scanner has been developed. The detection rate of benign prostatic hypertrophy and prostatic cancer in males over 55 years of age was approximately 30% and 0.6%, respectively.
