ScienceDaily (Oct. 5, 2010) — A new research study published in The FASEB Journal may change how sports injuries involving muscle tissue are treated, as well as how much patient monitoring is necessary when potent anti-inflammatory drugs are prescribed for a long time. That's because the study shows for the first time that inflammation actually helps to heal damaged muscle tissue, turning conventional wisdom on its head that inflammation must be largely controlled to encourage healing.

Zhou and colleagues found that the presence of inflammatory cells (macrophages) in acute muscle injury produce a high level of a growth factor called insulin-like growth factor-1 (IGF-1) which significantly increases the rate of muscle regeneration. The research report shows that muscle inflammatory cells produce the highest levels of IGF-1, which improves muscle injury repair.

Maybe this is how prolonged inflammation increases cancer incidence.
Too much of a good thing.
