ABSTRACT
Curcumin is derived from traditional Chinese medicine turmeric and can be used for chemoprevention and treatment of various cancers. Recent studies have shown that curcumin can participate in the regulation of various molecular signal transduction pathways, regulate the levels of reactive oxygen species, and regulate the inflammatory microenvironment to inhibit the occurrence of tumors. In addition, curcumin can inhibite the proliferation of tumor cells and promote apoptosis of tumor cells. Here, the paper reviews the mechanism of action of curcumin in cancer prevention and treatment and the new progress in the clinical trials, aiming to provide a basis for research in related fields.
