PATHOLOGY

Pathology is the study of diseases. It looks at how diseases start, what symptoms they cause, and what they are like. A pathologist is a doctor who studies diseases to help diagnose and treat them.

• A pathologist might examine a tissue sample from a patient to determine if they have cancer.
• Pathology can also involve studying the causes of diseases, such as genetic mutations or environmental factors.

These examples show how pathology is used to diagnose and understand diseases. By examining tissue samples and studying the causes of diseases, pathologists can help doctors provide better treatment for their patients.
