title: [Tumor formations and cell proliferation in invertebrates].
abstract: Critical analysis of the present status of invertebrate oncology through an appreciation of data relative to the various origins of tumors : spontaneous formations, cell proliferations induced by viruses, so-called hereditary tumors, effects of injuries induced by carcinogenic agents, irradiations or hormones on the formation of neoplasms in invertebrates. Attempts are made to interpret these data as compared with those obtained in medical and veterinary oncology. The possible direction of studies on invertebrates towards comparative oncology is considered, emphasizing the great usefulness for the medical research to study the phylogenetic development of oncogenesis.
