Tumor classification is a research area focused on categorizing tumors based on their characteristics, such as genetic mutations, cell type, and growth patterns. This classification is important for understanding the behavior of different types of tumors, predicting patient outcomes, and determining the most effective treatment options. Researchers use a variety of techniques, including molecular profiling, imaging studies, and histopathological analysis, to classify tumors into different subtypes and identify potential targets for therapy. Ultimately, tumor classification research aims to improve diagnosis and treatment strategies for cancer patients.
