Introduction: DNA damage is a ubiquitous threat to genomic integrity, posing a constant challenge to cells’ survival and proliferation. In cancer, dysregulation of DNA damage response (DDR) pathways can lead to genomic instability, a hallmark of tumorigenesis. Moreover, The complex mechanisms of DNA damage, repair, and mutagenesis in cancer development are essential for identifying therapeutic targets and then devising effective treatment strategies. This blog explains the molecular intricacies of DNA damage and repair in cancer, highlighting vulnerabilities that can be exploited for therapeutic intervention.   DNA Damage and Repair Mechanisms: DNA damage can arise from various sources, including endogenous metabolic…
