Washington, 28 mar (EFE).-rates of cancer mortality in United States remained in decline between 1998 and 2008, according to a national report on cancer (1975-2008) published today, linking some cases with obesity and sedentary life.
The report reveals that overall cancer mortality rates have continued to decline since the beginning of the Decade of the nineties in men, women and children and a 1.6 per cent per annum between 2004 and 2008 were reduced on average.
Between this period the incidence rates of all cancers as a whole declined 0.6 per cent annual for men and stabilized in women.
Researchers of the centres for the Control and prevention of diseases (CDC), the North American Association of central cancer registries, the National Cancer Institute and the American Cancer Society collaborated on this report which warned that excess weight and lack of activate physical proper are risk factors that can be avoided.
In particular, refer to the esophageal adenocarcinoma, colon cancers and straight; kidney, pancreatic, endometrium and women breast cancer postmenopausal have been associated to overweight and obesity.
The International Agency for research on cancer (IARC) concluded that a quarter to a third of the common cancers in the United States and other industrialized nations are caused by the combined effects of excess weight and lack of adequate physical activity.
In people who do not smoke, maintain a healthy weight and sufficient physical activity may be one of the most important ways of preventing cancer.
“while currently there is a decrease in the incidence of many types of cancer, if obesity continues at the current pace, believe that these improvements in the incidence will be invested and will increase over time,” warned in a statement the doctor Jeffrey Meyerhardt expert in colorectal cancer at the Dana-Farber Institute and author of several studies investigating the impact of exercise on survival rates for patients with Cancer Colorectal.
The good news is that some of the risks of cancer that drew attention to the report can be reduced through changes in lifestyle, noted for its part Edward Benz, director of the institution. “many of the things that are still a problem in these statistics are modifiable”, he said.
Between racial and ethnic groups the highest cancer incidence rates between 2004 and 2008 were presented in men of black and white women.
Rates of mortality during this period were higher in men and black women, but these groups showed higher reductions in the period from 1999 to 2008, compared with other racial groups.
Experts point to differences in rates of mortality by racial and ethnic group, sex, and location of the cancer “may reflect differences with regard to risk factors, as well as to the access and use of tests for detection and treatment”.
“Although the continuous reduction in cancer mortality rates is good news, the persistent disparity in racial and ethnic groups continues to be cause for concern”, said Betsy Kohler, President of the Association of central records of U.S. cancer.UU. (Naaccr), who pointed out that this type of in-depth analysis “can give clues to understand and address those differences”. EFE
