Pathology

Pathology is the precise study and diagnosis of disease. The word pathology is from Ancient Greek πάθος, pathos, "feeling, suffering"; and -λογία, -logia, "the study of". Pathologization, to pathologize, refers to the process of defining a condition or behavior as pathological, e.g. pathological gambling. Pathologies is synonymous with diseases. The suffix "path" is used to indicate a disease, e.g. psychopath.

Pathology addresses 4 components of disease: cause/etiology, mechanisms of development (pathogenesis), structural alterations of cells (morphologic changes), and the consequences of changes (clinical manifestations).

Pathology is further separated into divisions, based on either the system being studied (e.g. veterinary pathology and animal disease) or the focus of the examination (e.g. forensic pathology and determining the cause of death).
