...book tries to develop. How much of present widespread violence can be attributed to poor impulse control? And how many of these cases are related to brain malfunctions? If an individual's threshold for violent action is low, is it due to a gross cerebral defect, such as a tumor? Or is it the result of progressive environmental influences, such as living in a lower-class urban environment or watching violent television programs, which might create a cerebral predisposition to violence on a molecular (memory-bank) level...
...question that today such an approach is desperately wanting. Several weeks before climbing a tower in Austin, Texas, from which he murdered 17 people by rifle, Charles Whitman had gone to a psychiatrist and spoken of doing just that. After Whitman was killed, autopsy revealed a brain tumor-easily detectable by a simple medical procedure...
...issues were less clear-cut in the case of Mrs. Santa Teriaca, 51, a Cleveland housewife. Bothered by the worsening of a chronic limp, she had an operation for the removal of a small tumor on her spinal cord, and ended up paralyzed from the chest down. Her doctors claimed that the result was unfortunate but unavoidable. Mrs. Teriaca replied that she had been unaware of the risks. "The doctors," she told the court, "only told me that it would be as simple an operation as a tonsillectomy." The defendants apparently agreed that they should have told her more about...
Such revelations have been surprisingly accurate. In one case, In-111 disclosed a lung tumor six months before it became visible on X rays. In another, the scanner showed a cancer six centimeters wide. From the operating room, the pathologist studying the growth phoned Hunter to say that the radiologist had been wrong-the cancer was only three centimeters wide. Later, he corrected himself; more careful examination revealed a spread of malignant cells through the six-centimeter zone...
...Ridge Associated Universities, Biologist Raymond L. Hayes and Physician C. Lowell Edwards have given Ga-67 intravenously to 84 patients. At first it shows no selectivity between normal and tumor tissues. But after 48 hours the concentrations are enormously different in diseased and healthy areas: 10 to 1 for some blood cancers, and as high as 100 to 1 in muscle cancer. Ga-67's spectrum of cancer selectivity is probably the widest of any radioisotope...
