Brain cancer, the abnormal and uncontrollable growth of cells in the brain, most often affects children between the ages of 3 and 12 and adults between the ages of 40 and 70, according to the National Cancer Institute. Because the brain serves as...
Brain tumors are masses of cells that have grown abnormally and out of control within the brain tissue. When tumors form they can cause symptoms of headache, dizziness, movement disorders, numbness and tingling and other issues depending on the...
A diagnosis of astrocytoma, a type of brain tumor, can mean many things depending on the specific characteristics of the individual tumor. Astrocytomas can range from benign grade 1 tumors to highly aggressive grade 4 cancer. They may be found in...
Brain cancer describes a disease characterized by the abnormal, rapid and uncontrollable growth of cells in the brain. Brain cancer can originate in several different types of cells, creating different forms of cancer. Any of these forms of cancer...
Brain tumors almost never form from neurons, because the neurons intrinsically lack the ability to divide and grow, which is a key part of cancer. Instead, many brain tumors come from cells that support and nourish the neurons. These cells, called...
The brain contains three main parts: the forebrain, the midbrain and the hindbrain. The cerebrum is the largest part of the brain. Located in the forebrain, it is divided into the frontal lobe, parietal lobe, occipital lobe and temporal lobe. The...
There are several diseases associated with epilepsy. According to the U.S. National Library of Medicine and the National Institutes of Health (NIH), epilepsy is a neurological disorder characterized by recurrent seizures or violent muscle spasms....
The National Cancer Institute reports that more than 35,000 people each year in the United States are diagnosed with a primary brain tumor, meaning a tumor that originated in the brain. There are three major parts of the brain which control...
A brain tumor is a group of malignant cells that are abnormally dividing and are not able to be controlled. Brain tumors are classified by the kind of cell from which they arise and their behavior pattern, and some are graded on how malignant or...
Glioblastoma, also known as Glioblastoma multiforme, is a grade 4 type of brain tumor that is almost always fatal. It is an aggressive tumor that involves the glial cells of the brain. According to the International Radiosurgery Association,...
A glioma such as a glioblastoma, also called glioblastoma multiforme, is a type of tumor that develops from the glial cells in the brain and central nervous system. Glial cells are supportive cell structures that bring nutrients and energy to the...
In general nerve cells within the brain are unable to duplicate and grow, which means that most brain tumors do not arise from cells. However, there are other tissues in the brain that serve the nerve cells, and these cells can form tumors....
A memorable movie line is from the Arnold Schwarzenegger film "Kindergarten Cop", when Schwarzenegger's character complains of a headache and one child suggests he has a tumor. Schwarzenegger replies, "It's not a tumor!" Had the character been...
The largest brain lobe in the cerebrum, the frontal lobe is responsible for essential brain functions, like language, judgment, memory, motor function, problem solving and impulse control, according to the Centre for Neuro Skills. Because of its...
Brain tissue includes nerve cells and glial cells. Glial cells nourish the brain and form the myelin sheath, which is the fatty material that insulates nerve cells and speeds transmission of nerve impulses. According to the Macmillan Cancer...
Glioma describes a type of brain tumor that originates in the glial cells in the brain --- those cells that do not carry nerve signals. Glial cells make up the supportive tissues in the brain, including the portion of the brain known as the...
Brain tumors result from an abnormal proliferation of cells in your brain. Typically, cells grow only when needed; however, occasionally, excess cells grow and create a tumor. Brain tumors are primary or secondary, meaning they start in the brain...
A glioma is a brain tumor originating in the glial cells, the support cells of the brain. Many gliomas are highly aggressive and respond poorly to treatment or require multiple treatments to deal with recurrences or regrowth of the tumor....
In 2009, 22,070 people were diagnosed with brain cancer, and 12,920 people died from the disease, according to the National Cancer Institute. Brain cancer, or a malignant brain tumor, can start in the brain as a primary tumor or from another...
The American Cancer Society states that the term "brain cancer" is not used as often as "brain tumor." Even though some brain tumors are not cancerous, they can still grow and cause damage to the brain and other problems throughout the body. When...
Starting with a craniotomy, whereby an opening is created in the skull, brain surgery allows the doctor to remove abnormal growths, or repair problems in the brain. The National Institutes of Health (NIH) states that brain surgery requires three...
A brain tumor is an abnormal growth by the cells in the brain. The cells reproduce themselves in an uncontrolled manner. These tumors can be benign (harmless) or malignant (cancerous). Primary brain tumors are growths that started in the brain,...
The brain and spinal cord are surrounded by cerebrospinal fluid, or CSF, and are enclosed within bony skull and the spinal canal. CSF is made by specialized cells in the lateral and fourth ventricles, or brain chambers, which communicate with the...
The International RadioSurgery Association says that brain cancer makes up 2 percent of cancers in the United States. One type of brain cancer is glioblastoma multiforme, a grade IV astroyctoma. Glioblastoma multiforme accounts for 50 percent of...
Glioblastoma multiforme is an aggressive, rapidly growing astrocytoma, or nerve-tissue tumor of the central nervous system. The tumor begins in star-shaped glial cells that form the essential elements of the nervous tissue especially in the brain,...
Glioblastoma multiforme is the most aggressive form of glial cancer, a brain tumor made up of a variety of glial cells which are supportive cells in the nervous system. These glioblastomas grow rapidly and are difficult to treat. Prognosis tends...
Glioma is a kind of brain tumor that occurs in specialized cells called glial cells located in the central nervous system that are supposed to protect the nerve cells normally. In this video learn more about this cancer and how to prevent and...
