Cancer is a leading cause of morbidity and mortality worldwide; therefore, effective measures for cancer prevention and treatment are in constant demand. The extracts of Inonotus obliquus (Chaga mushroom) demonstrate potent anti-tumor activities and have been used to treat cancer in several countries; however, the actual effect and underlying mechanisms are still unclear. In the present study, we aimed to investigate the effects of continuous intake of aqueous extract from I. obliquus on tumor suppression.
