Antimicrobial peptides (AMPs) are crucial constituents of inherent immunity and serve as vital components of human host defense, playing a pivotal role in combating invading microbial pathogens. Beyond their antimicrobial functions, AMPs also exhibit various other biological activities including apoptosis induction, wound healing promotion, and immune modulation. These peptides are found in various exposed tissues or surfaces throughout the body, such as eyes, skin, mouth, ears, respiratory tract, lungs, digestive, and urinary system. Additionally, certain AMPs such as LL‐37, HNP, and lactoferrin have shown potential as candidates for anticancer activity. Given the limited selectivity between normal and cancer cells exhibited by many current immunotherapeutic agents, the inherent properties of AMPs make them promising candidates for cancer treatment. Their abundance, bioavailability, safety profile, efficiency, and harmony with the host immune system position them as attractive tools in the fight against cancer. This review is aimed at exploring the potential anticancer properties of AMPs and elucidating their relationship with immunology and cancer immunotherapy.
