The author discusses the role of experimental oncological research in the prevention of malignant neoplasms, with special reference to the conclusions drawn from such research in the USSR. He points out that experimental research can contribute to cancer prevention in two ways: (a) by supplying information on the occurrence of carcinogenic substances in the human environment-in the atmosphere, in industry and in foodstuffs-and thus providing a rational basis for the introduction of measures to prevent cancer from arising; and (b) by throwing light on the series of tissue changes that may precede the development of the malignant tumour and hence making it possible, through the timely treatment and cure of known precancerous conditions, to prevent cancer from developing.
作者论述了实验肿瘤学研究在预防恶性肿瘤方面的作用，并特别提及了苏联此类研究得出的结论。他指出，实验研究可通过两种方式促进癌症预防：(a) 提供有关人类环境（大气、工业和食品中）致癌物质存在情况的信息，从而为采取预防癌症发生的措施提供合理依据；(b) 阐明在恶性肿瘤发展之前可能出现的一系列组织变化，从而通过及时治疗和治愈已知的癌前病变来预防癌症的发展。
