How Does DNA Sequencing Guide Treatment Decisions?
By identifying specific genetic alterations in cancer cells, DNA sequencing can assist in selecting the most effective treatments. For example, if a tumor harbors a mutation in the EGFR gene, targeted therapies such as EGFR inhibitors can be prescribed. Similarly, the presence of BRCA1 or BRCA2 mutations in breast cancer can guide the use of PARP inhibitors. This approach, known as precision medicine, aims to tailor treatments based on the genetic profile of an individual's cancer.
