What Is the Importance of Genetic Testing in Cancer?
Genetic testing can identify specific mutations in genes that may predispose an individual to cancer or influence the course of the disease. For example, testing for mutations in the BRCA1 and BRCA2 genes can guide preventive measures in individuals at high risk for breast and ovarian cancers. Additionally, identifying specific genetic mutations can help tailor targeted therapies that are more effective and have fewer side effects compared to traditional chemotherapy.
