There is no disease whose prime cause is better known. That the prevention of cancer will come there is no doubt. But how long prevention will be avoided depends on how long the prophets of agnosticism will succeed in inhibiting the application of scientific knowledge in cancer. This printing of THE CANCER BLACKOUT, reflects the many rapid changes in cancerology of the last few years, probably exceeding those of the last century. To understand cancer, the author writes, it must be considered in its entirety, not only as a disease that has often been mercilessly exploited, but also as a moral cause, as a scientific problem, and a battleground for bitter professional conflicts. How and why, the all powerful professional cliques and organizations have foisted their "treatments of choice" upon the public is realistically exposed. THE CANCER BLACKOUT reveals many new developments, heralding a new phase in cancer treatment, utilizing the achievements of independent workers and vindicating the heroic struggles of Koch, Ivy, Coffey and Humber, and others whose work is described.
