| Sumario: | © Springer Nature Singapore Pte Ltd. 2022.Cancer stands among the main causes of death worldwide characterized by a combination of different factors which drive tumor progression and invasiveness. Oxidative stress has been shown to possess a central involvement in cancer development for promoting an imbalanced microenvironment, favoring DNA mutations and damage to biological structures. Flavonoids are naturally occurring compounds present in plant-based foods, mainly fruits and vegetables, which exhibit notable antioxidant and radical scavenging activities. Due to their biological activities and their availability in nature, anthocyanins and flavonols, one of the flavonoids subclasses, have been studied as potential anticarcinogenic agents. This chapter summarizes the main therapeutic implications of some of the most efficacious diet-derivate anthocyanidins and flavonols, and its glycosides, on cancer chemotherapy and chemoprevention.
