This observer found that pulmonary growths commonly occurredafter intra-vascular (jugular vein) injections of sarcoma cells and rarely after the injec-tion of carcinoma cells; carcinoma commonly developed at the site of subcutaneousinjections—sarcoma rarely. These experiments indicate that the blood of rats is highlyresistant to carcinoma and slightly so to sarcoma, a feature equally characteristic ofhuman blood. Carl Lewin likewise attributes the rarity of cancer metastasis in labora-tory animals to the fact that the emboli are destroyed by the blood. A series of experi-ments performed by Levin and Sittenfield confirm the observations
