...Sweet had worked with the Massachusetts Institute of Technology's Physicist Gordon Brownell to develop a scanning machine that shows, with a high degree of accuracy, not only whether a brain tumor is present but, if so, precisely where it is. Dr. Sweet gave Holly an injection of radioactive arsenic, which has an affinity for tumors. An hour later she lay on a cot with her head between two scintillation counters to which scanning mechanisms were attached. Soon, as the counters picked up the gamma rays, the robot pens showed that the arsenic had concentrated in one part...
...first the doctors could not be sure of the reason, either. It might be the petitmal form of epilepsy, or a brain tumor. At Massachusetts General Hospital in Boston, Neurosurgeon William H. Sweet tried the electroencephalogram ("brainwave machine") and got indications of a local disorder, but nothing definite enough to justify major brain surgery. Another standard test (in itself fairly drastic), involving the injection of air into the brain cavities, showed nothing. Not long ago Holly Hyde would have had to wait for her condition to worsen, imperiling her understanding of language and perhaps endangering her life, before the doctors...
...their tally of scanned subjects (including normal volunteers for comparison) to well over 200. The machine, they hope, will save many a patient from dangerous surgery inside the skull for the sole purpose of getting information and will make the operation far surer in cases where a lurking tumor is disclosed...
...Archives of industrial Hygiene and Occupational Medicine. From samples of Los Angeles air (collected on both smoggy and clear days), the experimenters filtered out the chemicals. They painted the resulting goolon the backs of black mice. In little more than a year, 29% of the surviving mice developed malignant tumors. From gasoline-engine exhausts the researchers prepared a similar slime: 26% of the mice got cancer. Identical mice, under the same conditions but unpainted, showed not a single tumor...
...months persistent rumors have been making the rounds of Buenos Aires and cropping up abroad that Perón is ill. One version: the President has a brain tumor, plans to go to the famed Mayo Clinic at Rochester, Minn, in the near future for an operation. Another: he has an unidentified nervous disorder accompanied by fainting spells...
