Histopathology, the study of diseased tissues, heavily relies on genetic information. Genetic testing can complement histopathological findings to provide a comprehensive diagnosis. For instance, the identification of specific gene mutations in tumor cells can guide the classification of cancer types and inform treatment strategies. Techniques like fluorescence in situ hybridization (FISH) are used to detect genetic abnormalities at the chromosomal level, aiding in the diagnosis of conditions such as leukemia.
