Deaths due to cancer in the United States have continued to decline over the past decade, according to a yearly report on US cancer statistics released Wednesday.
Trends in death rates from cancer declined an average of 1.7 percent per year among men and 1.3 percent among women and children from 1998 to 2008, the latest period studied, said the Annual Report to the Nation on the Status of Cancer.
New cancer diagnoses also decreased less than one percent per year from 1996 to 2006 and leveled off from 2006 to 2008.
The report is compiled by the Centers for Disease Control and Prevention, the North American Association of Central Cancer Registries, the National Cancer Institute and the American Cancer Society.
The decline in death rates was seen for many common cancers, but there were some exceptions.
Among men and women, death rates due to pancreatic cancer rose slightly. Death rates from liver cancer and melanoma rose among men, and death rates from uterine cancer rose in women.
The report focused in the average yearly incidence rates of cancers and cancer deaths per 100,000 people in the population, and highlighted the problem of cancers caused by obesity in a nation where two in three people are overweight or obese.
"This report emphasizes that the growing obesity problem and decreased overall physical activity in our society compared to decades ago have a real impact on multiple diseases, including cancer," said Jeffrey Meyerhardt, a colorectal cancer expert at Harvard University.
"While we currently see declines in incidence of many cancers, if obesity continues at the current rates, I believe these improvements in incidences will reverse and increase over time."
Cancers that may be linked to eating habits and weight include colorectal cancer, as well as cancer of the kidney, esophagus, pancreas, breast and endometrial lining.
"If you watch your diet, exercise, and manage your weight, you can not only prevent your risk of getting many lethal forms of cancer, you will also increase your chances of doing well, if you should get almost any form of cancer," added Edward Benz, president of Dana-Farber Cancer in Institute in Boston.
The American Cancer Society has projected that 577,190 Americans will die of cancer in 2012 and more than 1.6 million new cases will be diagnosed.
