Ludwik Gross撰文:过去十年对肿瘤和白血病病因的研究已有重要进展。目前研究人员正在对肿瘤的性质和流行病学进行探讨。这可能会使某些动物中的肿瘤和白血病得到预防,最终也可能使人类的肿瘤得以预防。引起恶性肿瘤和白血病发生的主要病因是致癌病毒。这巳在大量动物实验中得到证实。
Ludwik Gross, author: There have been important advances in the study of the causes of cancer and leukemia over the past decade. Researchers are currently exploring the nature and epidemiology of cancer. This may lead to the prevention of tumors and leukemia in some animals, and ultimately to the prevention of human tumors. The main cause of malignant tumors and leukemias is cancer. This was confirmed in a large number of animal experiments.
