Pathology asks what causes disease, how damage develops, and why it produces particular signs and symptoms. It connects biological mechanisms with the changes seen in patients and laboratory samples.
Check what you understood with a short quiz.
Use what you learned in the previous lesson to solve real-world problems.
Cells and tissues leave visible clues when they are injured, infected, or growing abnormally. Patterns such as inflammation, cell death, and unusual growth can help distinguish one disease from another.
Biopsies, blood samples, and other specimens can confirm diagnoses, identify infections, and classify cancers. Pathology reports often guide decisions about surgery, medication, and further testing.
Disease is not always caused by one simple problem. Pathologists connect causes, cellular changes, organ effects, and symptoms to explain why similar complaints can come from very different conditions.
Anatomic and clinical pathologists work alongside laboratory scientists, physicians, researchers, and public health teams. Their work ranges from examining tumors and managing diagnostic laboratories to tracking outbreaks and developing molecular tests.
