Although previous studies using subgroup analyses have indicated that intervention duration (e.g., >12 weeks vs. <12 weeks) may moderate changes in IL-6 and CRP levels among breast cancer survivors, Bayesian network meta-analyses have identified high-intensity aerobic and resistance exercise as the most promising modalities for reducing inflammation, with total exercise volume influencing TNF-α concentrations (30, 31). Here, CRP is linked to breast cancer.
