High levels of sedentary behavior (prolonged sitting or television viewing) are independently associated with an increased risk of developing colorectal, endometrial, ovarian, and prostate cancer, as well as increased cancer mortality in women.
If you have a desk job or spend significant time watching TV, try to break up long periods of sitting. Stand up, walk, or move frequently. This is important for cancer risk reduction regardless of whether you exercise regularly, as sitting triggers unique biological risks like metabolic dysfunction and inflammation.
Sedentary behavior was associated with increased colorectal, endometrial, ovarian, and prostate cancer risk; cancer mortality in women; and weight gain in colorectal cancer survivors.
