Abstract
DNA repair mechanisms are critical to maintaining genomic stability and preventing mutations that may lead to cancer development. This article explores the various DNA repair pathways, such as base excision repair, nucleotide excision repair, homologous recombination, and mismatch repair, and their roles in safeguarding the genome. We discuss how defects in these repair mechanisms contribute to cancer susceptibility and how their dysregulation can lead to the accumulation of mutations. Furthermore, we explore potential therapeutic strategies aimed at enhancing DNA repair pathways to prevent or treat cancer.
