Pathology is the branch of medicine that deals with the study of the nature and cause of disease. Pathologists are medical doctors who specialize in diagnosing disease by examining tissues, cells, and body fluids. They use laboratory tests and microscopy to analyze these samples and to identify the underlying cause of disease.

Pathology is a critical component of medical practice, as it helps to guide patient management decisions, such as the choice of treatment or the need for further diagnostic testing. Pathologists work closely with other physicians and healthcare professionals to ensure that patients receive the appropriate care.
