| Remission | Subsidence of the signs and symptoms of a chronic disease |
| Precipitating factor | Trigger for an acute disease episode, not to be confused with a predisposing (risk) factor |

| Epidemic | Unexpected rise in the number of cases of an infectious disease within a given area |
| Communicable | Able to spread from one person to another |
| Atrophy | Decrease in the size of cells, resulting in reduced tissue mass |
| Hypertrophy | Increase in the size of individual cells, resulting in greater tissue mass |
| Hyperplasia | Increased in cell number that results in greater tissue mass |
| Metaplasia | Replacement of one mature cell type by another mature cell type |
| Dysplasia | Abnormal arrangement of cells accompanied by variations in cell size and shape, the presence of large nuclei, and increased rates of mitosis |
| Anaplasia | Loss of cell differentiation that tends to occur during tumorigenesis |
| Neoplasia | New growth that occurs during tumor formation; it may be benign or malignant |
| Infarction | Obstruction of the blood supply to an organ or region of tissue, typically by a thrombus or embolus, causing local death of the tissue |
| Necrosis | Death of most or all of the cells in an organ or tissue due to disease, injury, or failure of the blood supply |
| Liquefaction necrosis | Process by which dead cells liquefy under the influence of certain enzymes |
| Coagulation necrosis | Cell or tissue death characterized by protein denaturation |
| Fat necrosis | Breakdown of fatty tissue that occurs in response to certain infections or enzymes |
| Caseous necrosis | Type of coagulation necrosis characterized by the formation of a thick, yellowish, cheesy substance |
