Disclosed is a method of providing immuno-prophylaxis as well as malignant tumor immuno-therapy by administering a malignant-tumor-immunization and recession-provoking antigenic agent of malignant tumor tissue source to a living subject in an effective dosage and regimen to develop a sufficiently high level of defense against malignant tumor incipience, or to retard such tumor development and/or provoke its recession. The malignant-tumor-immunization and recession-provoking antigenic agent or tumor tissue source is a combination of: (a) the tritiated form of glycoprotein polysaccharide-like-antigenic substance (TPS) obtained by removing lipids and protein from a differential centrifugation sediment of a saline suspension of the mitochondrial fraction of cancer tissue, e.g. from carcinoma, fibrosarcoma, lymphoma, or melanoma: and (b) deoxyribonucleic acid (DNA) derived from the nuclear fraction of malignant tumor tissue; or (c) the untritiated form of the glycoprotein polysaccharide-like antigenic substance (TPS) described in (a) above.
