Identification of Risk Factors: GWAS can identify genetic variants that contribute to cancer susceptibility, enabling early detection and prevention strategies. Personalized Medicine: Understanding genetic risk factors allows for the development of personalized treatment plans tailored to an individualâs genetic profile. New Therapeutic Targets: Discovering genetic variants associated with cancer can lead to the identification of new drug targets. Improved Diagnostics: Genetic markers can be used to develop more accurate diagnostic tests for various types of cancer.
