Sitting Linked To 100,000 Cancer

November 4, 2011 by staff 

Sitting Linked To 100,000 Cancer, Here is a new risk for cancer of many of us can relate to – just sit too long. “It is likely that the longer you sit, the greater the risk,” Neville Owen, PhD, Baker IDI Heart Australia and Diabetes Institute, says in a news release.

Owen presented the research at a press conference today at the American Institute for Cancer Research annual conference in Washington, DC

Regular exercise has long been associated with reduced risk of certain cancers.

Now, experts say they have a better strategy. Exercise regularly and avoid prolonged periods of sitting.

Increased activity could prevent nearly 100,000 cases of breast cancer and colon cancer in the U.S. each year, says Christine Friedenreich, PhD, researcher and epidemiologist at Alberta Health Services in Canada. “These are only estimates,” he tells WebMD.

Friedenreich presents estimates of the conference.

Being sedentary is associated with increased inflammation and other indicators of cancer risk. More recently, it has to remain seated.

“We would like Americans to think of physical activity in a different way,” said Alice Bender, RD, a dietitian from the American Institute for Cancer Research at the press conference.

The goal, says Bender, should be to find time to exercise regularly, while reducing prolonged sitting. “We want people to think of” doing time “,” time out “and is equal and protection against cancer.”

The American Institute for Cancer Research now recommends that American adults who feel part of the day takes one or two minutes of”,” breaks every hour.

Time being and cancer risk
“Sitting Time is becoming a strong candidate to be a risk factor for cancer itself,” says Owen. The link does not depend, he says, in body weight or level of exercise.

In his research, Owen waist circumference measured, inflammation and other indicators of heart disease and cancer risk. “We found that even breaks as short as one minute can reduce these biomarkers.”

The study was published in the European Heart Journal.

Along with less area, Friedenreich updated the evidence linking physical activity with reduced risk of cancer by reviewing over 200 studies.

“Now we can say that there is convincing evidence that the activity reduces the risk of colon cancer and breast and endometrial cancer, probably,” he tells WebMD.

There is weaker evidence of the effect of exercise on lung, prostate, and ovarian cancer risk, she says.

For colon cancer, studies showed that people who exercised the most (and the amount varies from study to study) had a 30% or 35% reduction in risk compared with people who were less active, says .

In studies on exercise and breast cancer, the most active reduced their risk of 20% or 30%, compared with less active.
