- 1. Histopathology is a branch of pathology that involves the examination of tissues and cells under a microscope to study the changes or abnormalities in their structure. It plays a crucial role in the diagnosis of diseases such as cancer, infections, and inflammatory conditions. By analyzing tissue samples, pathologists can provide valuable insights into the nature and extent of diseases, which helps in determining the appropriate treatment strategies. Histopathology also serves an essential role in research, contributing to our understanding of disease mechanisms and the development of novel therapies.
