At the Mississippi River Valley Medical Association conference in Cincinnati last week, Dr. Gustave Kolescher of the Michael Reese Hospital staff exhibited four patients who had been clinically cured of cancer and whose cases at first had been regarded as hopeless. This was the First announcement of the success of Dr. Kolescher's treatment made to the public. It is the opinion of Dr. G. L. Perusse, superintendent of Michael Reese, that almost any case of incipient cancer can be stopped.
