...roving surgeon flew in, and at Dr. Dooley's request removed what he could of the lump, sent it to the laboratory for testing. Last week Dr. Dooley was back in the U.S. on the strength of the lab report: sarcoma-a fast-spreading cancer, often quickly fatal...
...Hottest Thing. "Right now," says National Cancer Institute's Heller, "the hottest thing in cancer is research on viruses as possible causes." The Rockefeller Institute's Dr. Peyton Rous showed as long ago as 1911 (his findings were unpopular at the time) that one cancer (sarcoma) in chickens is caused and can be transmitted by a virus. Over the years, viruses were found to cause other tumors in birds and lower animals. But the gap between them and man seemed unbridgeable. Then the University of Minnesota's Dr. John J. Bittner showed that breast cancer in certain...
...myeloid leukemia in adults, Hodgkin's disease, rhabdomyosarcoma (a rare muscle cancer), Wilms's tumor (in the kidney, present at birth), cancer of the adrenal glands, and choriocarcinoma (mainly in women, and arising from placental material). The list includes four major types of cancer-leukemia, lymphoma. sarcoma and carcinoma. This offers some hope that drugs effective against all the many forms of cancer can be found...
...took material from a tumor on the bird's breast, ground it ultrafine to smash the very cells, filtered the stuff through silica so that not even a broken cell could pass, and injected the liquid into healthy chickens. They soon developed cancers of the same type (sarcoma) as the original...
There is no longer any doubt that Rous's experiments were superbly executed and that his conclusions were sound. The Rous sarcoma and many others in a growing family of animal tumors are now known to be caused by viruses, although the definition of viruses (ultramicroscopic particles on the borderline of the animal and chemical kingdoms) may have to be revised to cover them all. It still seems that something more than the virus alone is needed to trigger the outbreak of cancerous growth, e.g., chemical or physical irritation. But the importance of the virus can no longer...
