The sequence of events from inception of a cancer to tumour formation to disease to death is governed by unpredictability at each step. An earlier event in this sequence is not necessarily followed by the next one. The scare-mongering statistics by cancer societies are generally based on the assumed invariable progression along the above sequence of events. This 1938 article has undiminished relevance in 1994. No mode of cancer therapy can cure cancer, all attack its detectable manifestation.
All therapies come on the scene when the silent spread of cancer is a fait accompli.
They have nothing to do with human or animal cancers. Successes gained in test tubes have remained restricted to the test tubes only. Cause and Prevention Chapter Four makes it clear that cancerology has been searching for a cause that never was. What has no cause can have no prevention either. Genetics Cancer is an eminent vertebrate feature that functions at the herd level, mediated by multifactorila inheritance.
