問題詳情

依下文回答第 46 題至第 50 題The list of cancer-causing agents is long—and getting longer. Experts already tell us to avoid smoking, exposure to UVradiation from the sun and even air pollution since these factors can increase the risk of cancer. Now the World HealthOrganization says hot drink like coffee and tea belong on that list too.The group’s International Agency for Research on Cancer (IARC) looked at about 1,000 studies that investigated aconnection between high-temperature drinks and cancer. Based on the available evidence, they conclude that drinkingvery hot beverages—anything above 149℉(65℃), which is significantly cooler than most coffee served in restaurantsand cafés—is linked to a higher risk of cancer of the esophagus.Hot drinks now join a list of 79 other substances—including red meat, emission from frying foods, DDT and thehuman papillomavirus—that have been deemed by the agency to be a “probable” carcinogen in humans.Of course, that doesn’t mean a steaming cup of coffee every morning will always cause cancer. And in fact, thesame report had some good news for coffee lovers. Back in 1991, the last time the IARC looked at coffee, the groupdeemed it a “possible” carcinogen based on data linking it to bladder cancer. But in light of a large, newer body ofresearch, the group says there isn’t adequate evidence to classify coffee itself as a carcinogen—it’s the temperature atwhich it’s consumed that seems to tip the balance.Experts think that people with a condition called Barrett’s esophagus, which often precedes esophageal cancer, areespecially vulnerable. And while a small risk exists for everyone, Dr. Otis Brawley, chief medical and scientific officerat the American Cancer Society, says smoking and excessive drinking are much bigger threats to health than piping-hotcoffee or tea.Some research has shown that coffee and tea may even prevent cancers in several other parts of the body. Moreresearch is needed, but for now, experts are advising only minor changes to people’s morning routines.“It’s a pretty simple message,” says Mariana Stern, a professor at the university Southern California and one of theIARC’s working-group members. “You can drink your favorite hot drink. Just make sure the temperature is notsuperhot.”
