What is the term for the study of causes of disease?

The term "etiology" refers specifically to the study of causes or origins of diseases. It encompasses the investigation of factors that contribute to the development of illnesses, including biological, environmental, genetic, and lifestyle influences. Understanding etiology is crucial for healthcare professionals as it aids in prevention, treatment, and management of diseases by identifying what triggers them.

Pathology, while related and often discussed in conjunction with etiology, focuses on the structural and functional changes in tissues and organs caused by disease, meaning it deals with the consequences of disease rather than the origins. Symptomatology is the study of symptoms and their effects on the body and can help in diagnosing conditions, but it does not address the underlying causes. Diagnosis is the process of identifying a disease based on symptoms, tests, and other clinical findings, again placing emphasis on recognizing conditions rather than understanding their causes.
