CANCER - GENERAL |
|
Cancer is a class of diseases or disorders characterized by uncontrolled division of cells and the ability of these cells to invade other tissues, either by direct growth into adjacent tissue through invasion or by implantation into distant sites by metastasis. This unregulated growth is caused by damage to DNA, resulting in mutations to genes that encode for proteins controlling cell division. Many mutation events may be required to transform a normal cell into a malignant cell. These mutations can be caused by chemicals or physical agents called carcinogens, by close exposure to radioactive materials, or by certain viruses that can insert their DNA into the human genome. Mutations occur spontaneously, or are passed down generations as a result of germ line mutations.

RADIOLOGY |
|
Radiology is the medical specialty that utilizes and interprets imaging technologies to diagnose disease. Traditionally it was the branch of medical science dealing with the medical use of X-rays emitted by X-ray machines or other such radiation devices for the purpose of obtaining visual information as part of medical imaging. Radiologists now also use all other imaging technologies (such as ultrasound, computed tomography (CT) and magnetic resonance imaging) to diagnose or treat disease. Interventional radiology is the performance of (usually minimally invasive) medical procedures with the help of medical imaging.

STRESS TEST |
|
A cardiac stress test is a medical test performed to evaluate the arterial blood flow to the myocardium (heart muscle) during exercise compared to blood flow while at rest. In other words, it is a determination of the myocardial perfusion reserve. Stress tests also reveal overall physical fitness. Stress test abnormalities reflect inadequacies of blood flow to the left ventricular heart muscle more than other regions of the heart.

STROKE |
|
A stroke, also known as cerebrovascular accident (CVA), is an acute neurologic injury whereby the blood supply to a part of the brain is interrupted, either by a clot in the artery or if the artery bursts. The result is that the part of the brain perfused by that artery no longer can receive oxygen carried by the blood and it dies (becomes necrotic) with cessation of function from that part of the brain. In addition to tissue death, hemorrhages also cause damage from physical impingement of blood on the brain tissue. Stroke is a medical emergency and can cause permanent neurologic damage or even death if not promptly diagnosed and treated. It is the third leading cause of death and adult disability in the US and industrialized European nations (Jauch, 2005).
