Three randomized controlled trials found that resistance training prevented increases in a biomarker of inflammation (CRP) in breast cancer survivors.
“The study also found that women who increased their strength by 10% or more reduced CRP by 31% compared with women who improved less. Increases in serum CRP levels in breast cancer survivors have been associated with poorer outcomes. For example, a one-unit increase in CRP levels is linked to a 21% increase all-cause mortality and an 18% increase in breast cancer-specific mortality.”
