How is Genetic Testing Used in Cancer Diagnosis and Treatment?
Genetic testing can identify mutations in genes associated with increased cancer risk. This information can guide decisions about surveillance, preventive measures, and treatment. For example, individuals with BRCA mutations might opt for increased screening or preventive surgeries. Genetic testing also plays a vital role in personalized medicine, where treatments are tailored based on the genetic profile of the tumor. Targeted therapies, such as Herceptin for HER2-positive breast cancer, are examples of how genetic information can direct treatment.
