Cancer Risk Inflammation Markers
Several inflammation markers that can readily be measured in the blood are linked to cancer. These markers include C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor (TNF). Â A study on 439 women who exercised and lost weight reported a reduction in CRP of 42% and 23% drop in IL-6 levels. These reductions in inflammation marker associated with exercise and weight loss are greater than those seen with anti-inflammatory medicine.
Excessive body fat is also inflammatory so losing any weight is helpful in reducing the inflammatory load in the body. This particular study showed that exercise alone did not reduce inflammation, though some previous studies have shown a reduction in inflammation related to exercise.
Being overweight many times is associated insulin resistance and higher insulin levels. Insulin promotes inflammation and cancer cell growth. Losing weight and exercise can improve insulin resistance.
