IL6 and breast cancer: The pre-exercise inflammatory markers were higher with the intervention treatment than placebo (TNFα, BC 3 vs PL 2.1 pg/mL; IL-6, BC 12 vs 10 pg/mL and IL-10, BC 80 vs 60 pg/mL) and oxidative stress marker higher on the intervention than placebo (FRAP, BC 0.15 vs 0.14%), although none of these reached significance.
