Show Doctor Describes Cancer Test Mode iVetp Device Shoics Disease In Stomach Early. NEW YORK. An electric method that its originator maintains reveals cancer of the stomach in its early stages, before it can be detected by X-rays, was described here by Dr. Jose Risco, Peruvian physician, who has been carrying on research on cancer at the Institute for Scientific Investigation, University of Havana, Cuba. Dr. Risco said that he described de-scribed the details of his new diagnostic diag-nostic technique at the recent meeting meet-ing of gastroenterologists at Chicago, Chica-go, where he presented a scientific paper in collaboration with Dr. Men-endez Men-endez Feros, also of Havana. The method consists of inserting a tube containing two electrodes into the stomach and determining the electrical conductivity of the stomach stom-ach by means of a galvanometer. Experiments on animals and more recently on 200 human cases, Dr. Risco reported, have revealed that in the presence of cancer in the stomach the electrical conductivity is from two to six times higher than in the normal stomach. When a non-malignant ulcer is present, the conductivity, remains normal, he said. A similar method for detecting early stomach cancer, by far the most prevalent form of cancer among males in the United States, was reported in April, 1942, by Dr. Edmund N. Goodman of the College of Physicians and Surgeons, Columbia Colum-bia university, who found that the electrical potential of the stomach, after the ingestion of milk, had one characteristic pattern for normal persons, another for benign stomach ulcers and a third for stomach cancer. can-cer. Much further work will have to be , done, it was pointed out, before either ei-ther of these tests can be accepted accept-ed as definite. ' |
