Every hour spent sitting down increases cancer risk by nearly a tenth

Each extra hour sitting down may raise your risk of deadly cancer, a study suggests.The average American spends between six and 10 hours a day sitting and engaging in sedentary behaviors like watching TV or working at a desk. Science has long shown that sedentary behavior raises the risk of obesity, diabetes, heart disease and osteoporosis.Now, researchers in Scotland have found sitting may lead to a higher chance of developing and dying of multiple forms of cancer. The team combed through health data from nearly 100,000 adults who wore activity monitors for a week and were then followed for more than a decade after. They found that prolonged sedentary behavior - spending at least 90 percent of a 30-minute interval sitting - was linked to a three percent higher risk of developing cancer and a nine percent greater chance of dying from the disease.And the risk of cancers linked to obesity, such as pancreatic and colon cancer - increased by five percent. However, the team also found replacing just 30 minutes of sitting a day with light exercise like walking was associated with an 18 percent lower chance of dying from cancer. A new study found each extra hour of uninterrupted sitting may raise your risk of cancer by nine percent
