A tumor is any growth of abnormal cells, or the uncontrolled growth of cells. This article is about primary brain tumors. These start in the brain, rather than spreading to the brain from another part of the body. See also: Brain tumor - metastatic (cancer that has spread to the brain) Brain tumor - children
|
 |
A brain tumor is an abnormal growth of tissue in the brain. Unlike other tumors, brain tumors spread by local extension and rarely metastasize (spread) outside the brain.
|
 |
A brain tumor is an abnormal growth of tissue, either malignant (cancerous) or benign (noncancerous), in the brain. Each year, more than 17,000 brain tumors are diagnosed in the United States.

A stroke is an interruption of the blood supply to any part of the brain. A stroke is sometimes called a "brain attack."
|
 |
A stroke is the sudden death of brain cells in a localized area due to inadequate blood flow. A stroke occurs when blood flow is interrupted to part of the brain.
|
 |
Symptoms of a StrokeDuring a stroke, blood stops flowing to part of the brain. This can damage areas in the brain that control the rest of the body.

Stroke, or cerebrovascular accident (CVA), is the third leading cause of death (after heart disease and cancer) in the United States and the industrialized countries of the world. The term " stroke, " which comes from subjects being suddenly " struck down " with neurological deficits, is commonly used by both professional and lay groups.
|
 |
Cerebrovascular accident (CVA) is the medical term for what is commonly termed a stroke. It refers to the injury to the brain that occurs when flow of blood to brain tissue is interrupted by a clogged or ruptured artery, causing brain tissue to die because of lack of nutrients and oxygen.
|
 |
A stroke, also called a cerebral infarction, is a life-threatening condition marked by a sudden disruption in the blood supply to the brain. A disruption in the blood supply to the brain starves the brain of oxygen-rich blood and causes the nerve cells in that area to become damaged and die within minutes.

For Caregivers: Preparing for Home Care After StrokeWhen your loved one returns home, you’ll both need time to adjust. You and the patient will have to transfer the skills learned in rehab to a new location.
|
|
A stroke, also called a cerebral vascular accident (CVA), is the sudden death of cells in a specific area of the brain due to inadequate blood flow. A stroke occurs when blood flow is interrupted to a part of the brain, either when an artery bursts or becomes closed when a blood clot lodges in it.
|
 |
Carotid Artery Problems: StrokeThe carotid arteries are large blood vessels that carry blood to the brain. When these arteries are healthy, the brain gets all the oxygen and nutrients it needs to function well.
|
 |
Stroke is the common name for the injury to the brain that occurs when the flow of blood to brain tissue is interrupted by a clogged or burst artery. Arterial blood carries oxygen and nutrition to the cells of the body.

A head injury is any trauma that leads to injury of the scalp, skull, or brain. These injuries can range from a minor bump on the skull to a devastating brain injury. Head injury can be classified as either closed or penetrating. In a closed head injury, the head sustains a blunt force by striking against an object. A concussion is a type of closed head injury that involves the brain. In a penetrating head injury, an object breaks through the skull and enters the brain. (This object is usually moving at a high speed like a windshield or another part of a motor vehicle.)

Hemochromatosis is a disorder that interferes with iron metabolism and results in excess iron deposits throughout the body.
|
|
Hemochromatosis is an inherited blood disorder that causes the body to retain excessive amounts of iron. This iron overload can lead to serious health consequences, most notably cirrhosis of the liver.
|
|
Iron is a mineral that the human body uses to produce the red blood cells (hemoglobin) that carry oxygen throughout the body. It is also stored in myoglobin, an oxygen-carrying protein in the muscles that fuels cell growth.
|
|
Hemochromatosis is an inherited blood disorder that causes the body to retain excessive amounts of iron. This iron overload can lead to serious health consequences, most notably cirrhosis of the liver.
|
|
Iron tests consist of four assays performed on serum or plasma to aid in the diagnosis and treatment of iron deficiency or iron overload. These tests are serum iron, total iron binding capacity (TIBC), serum ferritin, and serum transferrin.
|
|
Iron tests are a group of blood tests that are done to evaluate the iron level in blood serum, the body ' s capacity to absorb iron, and the amount of iron actually stored in the body. Iron is an essential trace element; it is necessary for the formation of red blood cells and certain enzymes.

|
|
Iron is a vital component of heme, the component of hemoglobin that transports oxygen in the blood. Iron deficiency is the world ' s most common cause of anemia (blood with low hemoglobin and red blood cell components).

Histiocytosis is a generic name for a group of syndromes characterized by an abnormal increase in the number of certain immune cells called histiocyte cells. These include monocytes, macrophages, and dendritic cells. There are 3 major classes of histiocytoses, but this article focuses on Langerhans cell histiocytosis, which is also called histiocytosis X. The other 2 classes are non-Langerhans cell histiocytosis (also known as hemophagocytic syndrome) and malignant histiocytosis syndrome (now known as T-cell lymphoma).
|
|
Histiocytosis X is a generic term that refers to an increase in the number of histiocytes, a type of white blood cell, that act as scavengers to remove foreign material from the blood and tissues. Since recent research demonstrated Langerhans cell involvement as well as histiocytes, this led to a proposal that the term Langerhans Cell Histiocytosis (LCH) be used in place of histiocytosis X.

The hypothalamus is an area of the brain that produces hormones that regulate thirst, hunger, body temperature, sleep, moods, sex drive, and the release of hormones from various glands.
|
 |
A pituitary tumor is an abnormal growth in the pituitary gland, the part of the brain that regulates the body's balance of hormones.
|
 |
Pituitary tumors are abnormal growths in the pituitary gland. Located in the brain, the pituitary gland is often referred to as the " master gland " of the body.
|
 |
Pituitary tumors are abnormal growths on the pituitary gland. Some tumors secrete hormones normally made by the pituitary gland.

Radiotherapy is the use of high-energy penetrating radiation (x rays, gamma rays, proton rays, and neutron rays) to kill cancer cells. Purpose The primary purpose of radiotherapy is to eliminate or shrink localized cancers.
|
|
Nonionizing radiation, in contrast to ionizing radiation, is electromagnetic radiation that does not have sufficient energy to remove electrons from an atom or molecules to form an ion (or charged particle) during a collision. Instead, it imparts energy to other particles, which typically results in heating.
|
|
The principal adverse health effects of sunlight are caused by the ultraviolet and visible radiation it contains. Ultraviolet radiation (UVR) comprises a spectrum of electromagnetic waves of different wavelengths, subdivided for convenience into three bands, which are measured in nanometers (nm):(1) UVA ( " black light " ), 315 to 400 nm; (2) UVB, 280 to 315 nm; and (3) UVC (which is germicidal), 200 to 280 nm.
|
|
Radiation and radioisotopes are extensively used medications to allow physicians to image internal structures and processes in vivo (in the living body) with a minimum of invasion to the patient. Higher doses of radiation are also used as means to kill cancerous cells.
|
|
Electromagnetic waves of extremely short wavelength (X-rays and gamma rays) and accelerated atomic particles (such as electrons, protons, neutrons, and alpha particles) deposit enough localized energy in an absorbing medium to dislodge electrons from atoms with which they interact and to disrupt chemical bonds. The loss of electrons creates particles known as " ions, " and these types of radiation are termed " ionizing radiation.

Subarachnoid hemorrhage is bleeding between the middle membrane covering of the brain and the brain itself. Specifically it occurs within the cerebrospinal fluid-filled spaces surrounding the brain (also known as the subarachnoid space). Patients with subarachnoid hemorrhage usually complain of the "the worst headache of their lives."
|
|
A subarachnoid hemorrhage is an abnormal and very dangerous condition in which blood collects beneath the arachnoid mater, a membrane that covers the brain. This area, called the subarachnoid space, normally contains cerebrospinal fluid.
