湖南统招专升本阅读理解真题(预防癌症)

　　Only three strategies are available for controlling cancer, prevention, screening and treatment. Lung cancer causes more deaths than any other type of cancer. A major cause of the disease is reliably known; there is no good evidence that screening is of much help; and treatment fails in about 90 percent of all cases. At present, therefore, the main strategy must be prevention. If, however, we consider not what research may one day offer but what today’s knowledge could already deliver that is not being delivered, then the most practicable and cost-effective opportunities for avoiding premature death from cancer,especially lung cancer, probably involve neither screening nor improved treatment, but prevention.

　　This conclusion does not depend on the unrealistic assumption that we can eliminate tobacco. It merely assumes that we can reduce cigarette sales appreciably by raising prices or by expanding the type of education that already appears to have had a positive effect on cigarette consumption by white-collar workers, and that we can substantially reduce the amount of tar delivered per cigarette. The practicability of preventing cancer by such measures applies not only in those countries, such as the U.S., where, because cigarette smoking has been common for decades, 25 to 30 percent of all cancer deaths now involve lung cancer, but also in those where it has become widespread only recently, China, for example, where lung cancer as yet accounts for only 5-10 percent of all cancer deaths.Countries where cigarette smoking is only now becoming widespread can expect enormous increases in lung cancer during the 1990s or early in the next century; unless prompt effective action is taken against the habit --- indeed, such increases are already plainly evident in parts of China.
