Pathology is a medical specialty that investigates the causes and effects of diseases through the examination of tissues, organs, bodily fluids, and whole bodies (autopsies). Pathologists, medical doctors with specialized training, analyze samples collected during procedures such as biopsies or surgeries to diagnose diseases and determine the best course of treatment. They play a critical role in understanding the nature of illnesses, identifying cancerous or infectious agents, and monitoring the effectiveness of treatments. Pathologists collaborate closely with other healthcare professionals to provide accurate diagnoses, guide patient management, and contribute to advances in medical research.
