Physicians have long sought a test which would warn them of the presence of invisible, embryonic cancers. Last week cancer specialists found new hope in a simple cancer test reported in Science by Drs. Theodore Herman Elsasser and George Barclay Wallace of New York University's Medical 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 rabbit aborted.
The urine of other patients with similar tumors, as well as their blood serum, produced the same result in pregnant rabbits.
