What is Human Pathology?
What does it mean?
Pathology is the study and analysis of 'diseases'. In layman's terms, these are ailments or health problems. Medically, disease refers to the alteration of 'structure' (anatomy) or/and function (physiology) of the human body. It is like a combination of changes in the human body caused by specific factors. This could simply mean an abnormal change e.g. growth or an abnormal function e.g. high blood pressure. The correlation of these is considered pathological and pathology is the study of these changes.
There's more to pathology than this. Check out the following!
Abnormal reactions of the body due to unknown or undetected causes:
Why is the study of pathology important?
Knowledge of pathology can help doctors to accurately diagnose various problems and determine the best possible solutions for the particular problem. Usually, a pathologist will provide the doctor the most possible or exact cause of a medical condition.
So what exactly does a pathologist do? Here are some examples.
The pathologist is also the specialist who will decide whether a particular breast lump is cancerous or not. The surgeon will take out the lump and send to the pathologist for histo-pathological examination. The pathologist will then prepare a report for the surgeon after inspecting the sample.
A forensic pathologist is a pathologist specializing in medico-legal investigations, conducting various scientific tests on objects or substances left at the scene of the crime. He or she must have a sound knowledge in pathology in order to help the police force to confirm the circumstances surrounding the cases.

There's more to pathology than this. Check out the following!
- Histo-pathology refers to changes seen under the microscope.
- Cytology refers to the study of individual cells in order to determine the abnormality.
- Physical Trauma e.g.: motor vehicle accidents, radiation.
- Chemical agents e.g.: poisons, toxic chemicals.
- Microbial agents (so tiny you can't see them) eg: pathogenic bacteria, virus and fungus.
- Nutritional deficiency e.g.: lack of vitamins.
- Deprivation of oxygen e.g.: arterial obstruction leading to stroke or heart attack.
Abnormal reactions of the body due to unknown or undetected causes:
- Leading to abnormal inflammation e.g.: rheumatoid arthritis.
- Leading to abnormal growth e.g.: cancer.
- Genetic error: e.g. Down's syndrome.
