...speech that satisfied neither friends nor enemies. But it was one that was inside the President as simple and pure as a diamond and had to come out, audience acceptance or not. "Well," he told TIME earlier in the day, his nose still scarred and red from his skin-cancer operation, "I'll be sitting at the same desk, so I can always duck...
When Ronald Reagan's doctors announced two years ago that the President suffered from colon cancer, the world also learned that his brother Neil had received the same diagnosis. That apparently incidental detail did not surprise cancer researchers. They have long known that family members can share a genetic predisposition to the disease, but the exact mechanism was a mystery. Last week scientists in Britain and Israel reported in the journal Nature that they had discovered that there is a faulty gene that triggers a rare form of colon cancer and found its general location. The discovery, said Sir Walter...
...accounts for less than 1% of the 170,000 new cases of colorectal cancerdiagnosed in the U.S. and Britain each year. That led Bodmer to ask, "Could the same gene be involved in the normal run of colon cancers?" The researchers analyzed tumors removed from 45 patients with common colorectal cancer. Result: the section of chromosome 5 that contains the FAP gene was missing in more than 25% of the cases. The finding suggested that such cancers occur only after one protective gene is lost and the other is inactivated. Says Gastroenterologist Sidney Winawer, of the Memorial Sloan-Kettering Cancer...
Should researchers pinpoint that genetic defect, the next step will be to develop a simple diagnostic test. Doctors now recommend that everyone over 50 periodically undergo routine, if unpleasant, examinations with a proctosigmoidoscope, a hollow, lighted tube that is inserted in the colon to look for signs of cancer. A blood test that could alert people that they carried a greater risk of developing colorectal cancer might motivate them to seek frequent checkups...
...been the nation's No. 1 termite killer. Last week the Environmental Protection Agency announced that Illinois-based Velsicol Chemical Corp., the sole manufacturer of the chemical cousins, had agreed to stop production. The company disputed that exposure to the pesticide, which has been linked to increased risk of cancer, is a health hazard. But Velsicol said it would stop making the compound, which under the brand name Termide is used in about 1 million U.S. homes each year, until the EPA is satisfied that it can safely be applied...
