A lesion is a non-specific term referring to abnormal tissue in the body. It can be caused by any disease process including trauma (physical, chemical, electrical), infection, neoplasm, metabolic and autoimmune.
Not all lesions require treatment.
[edit] Lesions produced in surgery
Lesions can also be inflicted intentionally during surgery, for example to specific regions of the brain to treat epilepsy.
[edit] Lesion studies in neurology
In psychology, a brain lesion means inflicting damage to an area of the brain i.e. by burning or cutting, in order to study the effects of disabling this area of the brain.
Lesion is derived from a Latin word which means "injury."
