Curcumin inhibits tumor growth and promotes tumor cells death in mice. LLC‐bearing female C57BL/6 mice were subjected to curcumin(100 mg/kg/day) by intraperitoneal injection for 15 day (n = 5). (a) Body weight of mice, tumor volume, and image of tumors in mice after curcumin treatment. (b) Ki67 immunofluorescence was conducted to detect the proliferation of lung cancer cells (scale bar = 25 μm). (c) H&E staining of tumor tissue sections was analyzed (left: scale bar = 1000 μm, right: scale bar = 50 μm). All results are expressed as the mean ± SD. **P < 0.002, ****P < 0.0001 versus control group. ^# P < 0.05, ^#### P < 0.0001 versus day 4
