A disease, condition, or trait that developed because of being exposed to something during your life.
- The events that lead to the development of a disease and the signs and symptoms that occur as the disease progresses.
- X-rays that utilize a contrast media to increase the radiodensity of selected fluids within the body, producing an image of the structures containing the fluid.
- A visual recording of differences in the rate of return & intensity of sound waves reflected off of objects within the body.
- A recording of the electrical activity of the brain, most often recording the cerebral cortex.
- Any procedure used to measure a persons ability to move air or the capacities of the respiratory system. Often referred to as PFTs (pulmonary function tests)
- The use of chemicals to kill cells within the body. Two main types of chemotherapy are used - to kill cancer cells or microorganisms.
- Any form of treatment that relieves signs & symptoms without curing a disease. May include the use of medication (such as a decongestant or pain reliever), therapeutic massage, counseling, physical therapy, orthotic devices...
- A consequence of a previous disease. (Example: rheumatic heart disease sometimes occurs following a strep infection)
- A morbid process or event occurring during a disease that is not an essential part of the disease, although it may result from it. (Example: blindness is a complication often associated with diabetes)
- The transfer of a harmful amount of energy. The energy may be mechanical, electrical, radiation, or thermal.
- Lacking in something that is essential. (Vitamin, glucose, protein, oxygen, water, ......)
- Growth of cells and tissue into new areas, resulting in a tumor. May be benign or malignant.
- A protective response of tissue to injury or infection. Causes an increase in blood flow and pain in the affected region, as well as leukocytosis.
- An increase in the number of white blood cells to more than 10,000 per mm3. A WBC count of 15,000-25,000 commonly occurs as a result of infection, inflammation, or hemorrhage.
- The excess fluid that accumulates at the site of inflammation. Contains a high level of proteins and neutrophils when compared to normal tissue fluid.
- A thick, creamy white or yellow fluid that accumulates at the site of inflammation. Also called pus.
- Replacing damaged tissue through the process of mitosis, restoring the tissue to its original condition.
- The over production of scar tissue that sometimes occurs in the dermis and subcutaneous layer and results in a mass of scar tissue that is often tender or painful.
- The shortening of scar tissue over time OR the shortening of muscle tissue as a result of fibrotic changes.
- The narrowing of any canal or opening, such as the intestine, a blood vessel, of a heart valve.
- The process of hardening. Can occur as the result of scar formation or the accumulation of deposits known as plaques.
- An early stage in the development of a disease or infection that is characterized by a lack of appetite and lack of energy. The time when a person feels as if they are "coming down with something".
- A severe, systemic allergic response that is characterized by vasodilation (which causes a severe drop in blood pressure) and bronchoconstriction (resulting in severe difficulty in breathing).
- The immune system's ability to recognize and not attack normally occurring tissues within the body
- The development of an infection from the time the infectious organism enters the body until the appearance of the first clinical signs and symptoms.
- Proteins produced by tumor cells that can be detected in screening tests of the person's blood.
INITIATORS (of cancer)
- Carcinogens that increase the rate of cancer cell production by activating oncogenes.
