Pathology is the branch of medicine that studies diseases, their causes, and effects on the body. It plays a crucial role in diagnosing illnesses by analyzing blood, tissues, and other body fluids. Pathologists help detect infections, cancer, and genetic disorders through laboratory tests. This field is divided into clinical pathology, which focuses on lab tests, and anatomical pathology, which examines tissues and organs. Advances in molecular pathology have enabled precise disease identification, leading to better treatments. Pathology is essential for early detection and management of various medical conditions.
