| Caused by a physician (example: chemo, medications) | Iatrogenic |
| Disease of unknown origin | Idiopathic |
| Response of tissue to local injury | Inflammation |
| Rubor, Calor, Tumor, Dolar, and Loss of Function | 5 Clinical Signs of Acute Inflammation |
| Severe generalized swelling; Edema throughout body | Anasarca |
| Edema that is more prominent in feet and ankles due to gravity | Generalized Edema |
| Edema that results from inflammation | Localized Edema |
| Interference with bloody supply | Ischemia |
| Thrombus, Clot | Occlusions |
| Detached thrombus or clot from vessel wall | Embolus |
| Localized area of ischemic necrosis; Cell death | INFARCTION |
| Necrosis due to occlusion; It’s an arterial disease of lower extremities | GANGRENE |
| Blood loss due to ruptured vessel | HEMORRHAGE |
| Minimal hemorrhages into the skin, mucous membranes, or serosal surfaces; Pinpoint or pinprick | PETECHIAE |
| Slightly larger hemorrhages than petechiaes | Purpura |

| Blood trapped within body tissues that accumulates | Hematoma |
| Blood trapped in pleural cavity | Hemothorax |
| Blood around heart and pericardial sac | Hemopericardium |

| 5 Carcinogens | Chemicals, Genetic Predispositions, Excessive UV light exposure, Radiation, and Viruses |
| Coughing up blood | Hemoptysis |
| Spread of cancer | Metastasis |
| Percentage of malignancy; How aggressive a tumor is and how well it'll respond to treatment | Cancer Grading |
| Extensiveness of tumor; How wide spread tumor is | Cancer Staging |
