The 20 known transformingoncgenes of retroviruses are defined by sequences that are transduced from cellular genes, termed proto-oncogenes or cellular oncogenes. Based on these sequences, viraloncgenes have been postulated to be transduced cellular cancer genes and proto-oncgenes have been postulated to be latent cancer genes that can be activated from within the cell to cause virus-negative tumors. The hypothesis is popular because it promises direct access to cellular cancer genes. However, the existence of latent cancer genes presents a paradox since such genes are clearly undesirable. The hypothesis predicts (i) that viraloncgenes and proto-oncgenes are isogenic, (ii) that expression of proto-oncgenes induces tumors, (iii) that activated proto-oncgenes transform diploid cells upon transfection, like viraloncgenes, and (iv) that diploid tumors exist that differ from normal cells only in transcriptionally or mutationally activated proto-oncgenes. As yet, none of these predictions is confirmed. Moreover, the probability of spontaneous transformationin vivois at least 109times lower than predicted from the mechanisms thought to activate proto-oncgenes. Therefore the hypothesis, that proto-oncgenes are latent cellular oncogenes, appears to be an overinterpretation of sequence homology to structural and functional homology with viraloncgenes. Here it is proposed that only rare truncations and illegitimate recombinations that alter the germline configuration of cellular genes, generate viral and possibly cellular cancer genes. The clonal chromosome abnormalities that are consistently found in tumor cells are microscopic evidence for rearrangements that may generate cancer genes. The clonality indicates that the tumors are initiated with, and possibly by, these abnormalities as predicted by Boveri in 1914 (Zur Frage der Entstehung maligner Tumoren, Jena, Fischer).
