摘要Intermittent fasting(IF)has emerged as a potential adjunctive strategy in cancer prevention,mitigation,and treatment.This narrative review synthesizes existing literature to explore the relationship between IF and cancer across 3 dimensions:prevention,mitigation,and treatment.We examine the underlying mechanisms by which IF may reduce cancer risk,including its effects on insulin-like growth factor 1 suppression,autophagy induction,and chronic inflammation reduction.Furthermore,we discuss IF's potential to enhance the efficacy of conventional cancer therapies by sensitizing cancer cells,promoting apoptosis,and reducing treatment-related side effects.While promising,the evidence is still limited,and further research is required to elucidate the long-term impact and optimal implementation of IF in cancer care.This review aims to provide health care professionals and patients with a comprehensive understanding of the potential benefits and risks associated with IF as a complementary approach in the oncology setting.
