Cancer is one of leading causes of death worldwide with the number of cases is expected to rise by 70% over the next two decades. These facts have lead researchers to continue studying how to treat cancer by find a new potential drug to replace the standard anti-cancer drugs such as doxorubicin which has side effects. Numerous natural compounds have been extensively investigated for their potential use in cancer prevention over decades. Curcumin from Curcuma longa has caught attention among researchers, is a highly promising natural compound that can potentially be used for chemoprevention of various cancers.
