The term pathogenesis means step by step development of a disease due to a series of changes in the structure and /or function of a cell/tissue/organ being caused by a microbial , chemical or physical agent.The pathogenesis of a
diseaseis the mechanismby which an etiological factor causes the disease. The term can also be used to describe the development of the disease, such as acute, chronic and recurrent. The word comes from the Greek "pathos", "disease", and "genesis", "creation".
Types of pathogenesis include microbial
infection, inflammation, malignancyand tissue breakdown.
Most diseases are caused by multiple "pathogenetical" processes together. For example, certain
cancers arise from dysfunction of the immune system( skin tumors and lymphomaafter a renal transplant, which requires immunosuppression).
Often, a potential etiology is identified by epidemiological observations before a pathological link can be drawn between the cause and the disease.
