By RONI CARYN RABIN ⓒ 2008 New York Times News Service The incidence of new cancer cases has been falling in recent years in the United States, the first time such an extended decline has been documented, researchers reported Tuesday. 최근 몇 해 동안 미국에서는 새로 암 환자들이 생기는 케이스가 줄어들어 왔으며, 이렇게 지속적으로 암 환자 발생이 감소된 것은 처음이라고 리서처들이 25일 말했다. Cancer diagnosis rates decreased by an average of 0.8 percent annually from 1999 to 2005, the last year for which data are available, according to an annual report by the National Cancer Institute, the American Cancer Society and other scientific organizations. 암으로 진단이 내려진 율이 1999년에서 2005년에 이르는 동안 연간 평균 0.8% 감소했다. 2005년은 데이터를 구할 수 있는 가장 최근의 해이다. 이러한 통계는 국립 암 연구소, 미국 암 소사이어티, 그리고 다른 과학 단체들의 연례 보고서에 따른 것이다. Death rates from cancer continued to decline as well, a trend that began some 15 years ago, the report also noted. It was published online in The Journal of the National Cancer Institute. 암으로 인한 사망률 또한 감소 추세를 보이고 있으며, 그러한 추세가 시작된 것은 약 15년 전이라고 이 보고서는 말하고 있다. 보고서는 온라인으로 국립 암 연구소 저널을 통하여 공개되었다. "Each year that you see these steady declines it gives you more confidence that we're moving in the right direction," said Dr. John E. Niederhuber, director of the National Cancer Institute, who is not an author of the report. "This is not just a blip on the screen." Death rates from cancer fell an average of 1.8 percent each year from 2002 to 2005, according to the new report. Although last year's report said death rates dropped an average of 2.1 percent each year from 2002-4, a 1 percent decrease in 2005, described as an insignificant change, lowered the average percentage for the period. The decline is primarily due to a reduction in death rates from certain common cancers, including prostate cancer and lung cancer in men, breast cancer in women and colorectal cancer in both sexes. The report attributes the reductions to changes in risk factors and screening patterns, as well as advances in treatment. The drop in annual incidence rates is harder to interpret. The data may point to a real decline in the occurrence of some types of cancer, experts said. Alternatively, the decline may reflect inconsistent screening practices, causing some cancers that used to be detected to now go undiagnosed. Christine Eheman, chief of the cancer surveillance branch at the U.S. Centers for Disease Control and Prevention, was more optimistic about the decline in cancer diagnoses. "I do think it's a good sign," Eheman said, "but I think we need to be very careful not to think we have this problem in any way beaten. We need to continue to do what we know works, and also find out why some cancers are not decreasing and not decreasing in certain populations."
