April 22, 2008 -- Some important U.S. cancer-prevention trends -- such as less smoking and more mammograms -- have stalled, the American Cancer Society warns.
Cancer deaths are down because of huge gains made over more than a decade of cancer-prevention efforts. Far fewer Americans smoke, far more get regular cancer screening, and lots more of us use sunscreen when we're outside. The result: Fewer U.S. cancer deaths.
We may have started taking these annual gains for granted, suggests Vilma Cokkinides, PhD, the American Cancer Society's strategic director for risk factor surveillance. Cokkinides is co-author of the American Cancer Society report, Cancer Prevention & Early Detection Facts and Figures 2008.
"These trends have been very favorable in the past, saving a lot of lives," Cokkinides tells WebMD. "It is concerning we are stalling. We want to see further improvements so we can save more lives."
Cokkinides is co-author of the latest American Cancer Society report on cancer prevention. Here's what she finds scary:
Smoking rates for adults and teens dropped from 1997 to 2003. But they haven't gone down since then -- and 21% of adults and 23% of teens still smoke.
For every dollar states spend on tobacco-control programs, the tobacco industry spends $24.
After a decade of increase, mammography rates are slightly declining.
Two-thirds of women who lack health insurance have not had a mammogram within the past two years.
Colorectal cancer screening rates are up, but fewer than half of Americans over age 50 get screened as they should.
Obesity -- directly linked to many kinds of cancer -- leveled off in adults at 34% of men and 36.4% of women. But obesity rates are soaring among teens, rising from 5% to 17% in just 20 years.
Just over a third of U.S. kids get at least an hour of physical activity at least five days a week.
