Cancer report energizes activists, not policyCancer report energizes activists, not policyCancer experts say for the most part that we already know what causes most cases of cancer and it's not pollution or chemicals lurking in our water bottles.Carbon fiber body kitIt's tobacco use and other unhealthy behaviors,Edge card, #x says Dr. Graham Colditz of the Washington University School of Medicine in St. Louis."The lack of physical activity, weight gain, obesity clearly account for 20 percent or more of cancer in the United States today," Colditz said in a telephone interview.The report, he said, gives people an excuse to ignore the risk factors most in their control."The damage is that it distracts us, as a society, from actually acting on the things that are already in our grasp. I can take tobacco as the best example," said Colditz, noting that more than 20 percent of Americans still smoke despite nearly 50 years of cancer warnings.And no state has even come close to banning smoking, although limits are going into place to restrict smoking in public.
"We know that alcohol causes 4 percent (of cancers) and we deal with that to too little extent, as well," said Colditz, an expert in the epidemiology of cancer. Red meat is a known cause of colon cancer, he adds. "We don't run out and ban all beef just because beef is a cause of colon cancer." #xUNDERSTUDIED OR OVEREMPHASIZED?Carbon fiber body kitSo it worries Colditz to see the two-member cancer panel -- Dr. LaSalle Leffall, professor of surgery at Howard University College of Medicine in Washington, and Margaret Kripke, an emeritus professor at the University of Texas M.D. Anderson Cancer Center -- recommend sweeping policy changes to focus on potential environmental causes of cancer."Maybe up to 4 percent of cancer in the western world is caused by contaminants and pollution and yet we are chasing new, unknown causes rather that focusing on acting on what we know," he said. "Things like this report are making it harder to move the nation to a healthier lifestyle." #xKenneth Cook, president of the Environmental Working Group, an activist group that conducts research into environmental health questions, disagreesCarbon fiber body kitwith the assessment that chemical causes of cancer are only in the single digits.相关的主题文章：
