Etiology is the branch of medical science that investigates the causes of diseases. It examines the origin and contributing factors of conditions, aiming to understand what triggers the onset of specific illnesses. This focus on causation is crucial in various fields, including epidemiology, preventive medicine, and therapeutic strategies. By identifying the underlying causes of a disease, healthcare professionals can develop appropriate treatments and interventions more effectively.

The other options, while related to the study of diseases, address different aspects. Effectiveness of treatment pertains to the results resulting from medical interventions. Symptoms refer to the signs and manifestations of an illness that a patient may experience. Pathology deals with the structural and functional changes in tissues caused by disease. Each of these areas is essential in healthcare, but they do not specifically define etiology.
