[Prevention of urological diseases can be a national benefit]

Early detection of urological cancers by means of mass screening would be beneficial to the nation, as can be seen in the advances in the detection of stomach and lung cancers. Medical students in Japan today should be studying the economics of medicine, that is, how to prevent cancer instead of studying economics to become prosperous after opening their own offices. This view should not be confined to our nation, but should be directed toward all of mankind in the whole world.
