The cell viability MCF10A cells treated with different concentrations of GA in pre (a), and post (b) red light irradiation. The cell viability of MDA-MB-231 cells treated with different concentrations of GA in pre (c), and post (d) red light irradiation. Low-level laser irradiation was used with 3 J/cm2 for 90 s. The results are expressed as the mean ± SD (n = 3), *P < 0.05 compared with control (untreated) group
