Cancer Test
Physicians have long sought a test which would warn them of the presenceof invisible, embryonic cancers. Last week cancer specialists foundnew hope in a simple cancer test reported in Science by Drs. TheodoreHerman Elsasser and George Barclay Wallace of New York University'sMedical School.
Two years ago, said the scientists, they examined a young man who had"a large embryonic cancer of the right testicle."
They injected his urine into the veins of a pregnant rabbit. The rabbitaborted.
The urine of other patients with similar tumors, as well as their bloodserum, produced the same result in pregnant rabbits.
The scientists then tested "the urines [and serums] of alarge number of patients with other types of malignant tumors . . . andin all instances abortion occurred."
"We have not had an opportunity for intensive study of thesubstance responsible for the [rabbits' abortions] . . ."concluded Drs. Elsasser and Wallace cautiously. "Work is beingcontinued."
