After decades of disputes with the government and with the United States Surgeon-General, U.S. tobacco company Philip Morris, the largest in the country, made a cynical publicity bid earlier this month when it at last recognized that smoking causes cancer and other major diseases and that tobacco is addictive...
Just when you thought you'd heard just about everything about gene research - scientists have supposedly isolated every predisposition from breast cancer to sugar addiction - a group of California doctors claim to have found the DNA strand responsible for the industrialized world's number one killer, heart failure. In a report released Thursday, the team of UC San Diego doctors told of mating mice genetically engineered to contain the gene phospholamban, or PLB, which they believed was responsible for heart failure, with mice that lacked the PLB gene. The resulting offspring did not develop heart failure. They also created mice...
Better communication will be even more important as treatments become more complex. Currently there's no screening test for finding lung cancer early. (Chest X rays almost always catch it too late.) But Dr. Claudia Henschke of the Weill Medical College at Cornell University in New York City and her colleagues believe they have found a way to identify very small tumors with low-dose CAT scans. It's a new approach that all smokers and ex-smokers, regardless of race, should keep...
First the CAT scan picks up suspicious-looking lesions in the lungs. Then a radiologist determines whether those nodules warrant further investigation. Most of the time, that means waiting a couple of weeks or months to see if they grow (only 1 out of 10 lesions is cancerous). Sometimes it means undergoing a biopsy. "We found that people were willing to wait," Henschke says, in order to avoid potential complications from unnecessary surgery. The still experimental scan costs $300 and is so far available only in New York City, Rochester, Minn., and Tampa, Fla. But if it becomes the next...
