[Does nutrition influence the propagation of neoplasms?]

In the last years, questions concerning the relationship between nutrition and the occurrence of neoplasms have been studied more intensively. The author discusses the possible involvement of water as a potential carrier of certain cylic hydrocarbons and radionuclides, and of nutrition per se. He treats problems related to, inter alia, bulk materials, polyethenoid fatty acids, the increase in fat consumption, trace elements, vitamins and the importance of the intestinal flora.
