What is the term used to describe a specialist who studies diseases?

The term for a specialist who studies diseases is "pathologist." Pathologists are medical doctors who specialize in diagnosing diseases by examining tissues, cells, and bodily fluids. They play a crucial role in medical diagnoses, allowing for the identification of diseases through laboratory analysis, including the examination of biopsies and other samples.

Pathologists are essential in guiding treatment decisions and monitoring disease progression, making their work pivotal in healthcare. They utilize various techniques, such as histology and cytology, to provide precise information about the presence and nature of diseases. This makes their expertise foundational for patient care across multiple medical disciplines.

Oncologists specialize specifically in cancer treatment, hematologists focus on blood disorders, and cardiologists deal with heart-related issues. While all these specialists contribute significantly to their fields, their scopes are much narrower compared to the broader role of a pathologist in studying diseases in general.
