DNA sequencing can reveal a wealth of information about cancer, including:
1. Driver Mutations: These are mutations that give cancer cells a growth advantage. Identifying driver mutations can help in the development of targeted therapies. 2. Tumor Heterogeneity: Cancer is often characterized by a high degree of heterogeneity. Sequencing can uncover the different subclones within a tumor, providing insights into tumor evolution and resistance mechanisms. 3. Germline Mutations: Some cancers are caused by inherited mutations. Sequencing the DNA of normal cells can identify germline mutations that increase cancer risk.
