Continuing Declines in Cancer Death Rates Since the Early 1990s
(3BL Media) Atlanta, GA - March 29, 2012 - Death rates from all cancers combined for men, women, and children continued to decline in the United States between 2004 and 2008, according to the Annual Report to the Nation on the Status of Cancer, 1975-2008. The overall rate of new cancer diagnoses, also known as incidence, among men decreased by an average of 0.6 percent per year between 2004 and 2008. Overall cancer incidence rates among women declined 0.5 percent per year from 1998 through 2006 with rates leveling off from 2006 through 2008. The report is co-authored by researchers from the Centers for Disease Control and Prevention, the North American Association of Central Cancer Registries, the National Cancer Institute, and the American Cancer Society. It appears early online in the journal CANCER, and will appear in print in the May issue.
The special feature section highlights the effects of excess weight and lack of physical activity on cancer risk. Esophageal adenocarcinoma, cancers of the colon and rectum, kidney cancer, pancreatic cancer, endometrial cancer, and breast cancer among postmenopausal women are associated with being overweight or obese. Several of these cancers also are associated with not being sufficiently physically active.
“This report demonstrates the value of cancer registry data in identifying the links among physical inactivity, obesity, and cancer,” said CDC Director Thomas R. Frieden, M.D. “It also provides an update of how we are progressing in the fight against cancer by identifying populations with unhealthy behaviors and high cancer rates that can benefit from targeted, lifesaving strategies, and interventions to improve lifestyle behaviors and support healthy environments.”
For more than 30 years, excess weight, insufficient physical activity, and an unhealthy diet have been second only to tobacco as preventable causes of disease and death in the United States. However, since the 1960s, tobacco use has declined by a third while obesity rates have doubled, significantly impacting the relative contributions of these factors to the disease burden. Excess weight and lack of sufficient physical activity have been linked to increased risk of cardiovascular disease, hypertension, diabetes, and arthritis, as well as many cancers.
“In the United States, 2 in 3 adults are overweight or obese and fewer than half get enough physical activity,” said John R. Seffrin, Ph.D., chief executive officer of the American Cancer Society. “Between children and youth, 1 in 3 is overweight or obese, and fewer than 1 in 4 high school students get recommended levels of physical activity. Obesity and physical inactivity are critical problems facing all states. For people who do not smoke, excess weight and lack of sufficient physical activity may be among the most important risk factors for cancer.”
