Term | Definition |
---|---|
Acute | Having a quick onset and lasting a short period of time with a relatively severe course |
Asymptomatic | Showing or causing no identifiable symptoms |
Atrophy | A reduction in size or wasting of cells, tissues, or organs due to poor nutrition or non-use |
Auto-antibody | Antibody acting against its own tissue or organism |
Autoimmune disorder | Disease in which antibodies form against and injure the patient’s own tissues, in contrast to the normal process in which antibodies form in response to foreign antigens. |
Benign neoplasm | Refers to a localized and generally noninvasive lesion |
Carcinoma | A malignant growth comprised of epithelial cells that tends to invade surrounding tissues and gives rise to metastases. |
Chronic | Presenting slowly and persisting over a long period of time |
Congenital | Existing at, and usually before, birth and resulting from genetic or environmental factors |
Degenerative | Refers to deterioration of the body usually associated with the aging process |
Diagnosis | The name of a disease an individual is believed to have |
Disease | Any abnormal disturbance of the normal function or structure of a body part, organ, or system that may display a variety of manifestations. |
Dysplasia | Abnormal tissue development |
Epidemiology | The investigation of disease in large groups |
Etiology | The study of the cause and origin of disease |
Hematogenous spread | Spread through the blood |
Hereditary | Genetically transferred from either parent to child and derived from ancestors |
Hyperplasia | Overdevelopment. |
Hypertrophy | Increase in number of cells and tissue resulting in an increased organ size without the presence of a tumor. |
Iatrogenic | Pertains to any adverse condition in a patient occurring as a result of medical treatment. |
Idiopathic | No identifiable causative factor |
Incidence | A statistical measure that refers to the number of new cases of a disease found in a given time period. |
