What is the Role of Pathological Data in Diagnosis?
Pathological data plays a pivotal role in the diagnosis of cancer. By examining tissue samples, pathologists can identify the type of cancer, such as carcinomas, lymphomas, and sarcomas. Molecular pathology can further classify cancers based on genetic mutations, providing a more precise diagnosis. For example, the presence of the HER2 gene in breast cancer can influence the choice of targeted therapy.
