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...
Gliomas arise from glial cells which make up the supporting tissues of the brain. According to the American Cancer Society, high grade malignant gliomas are the most common types of brain and spinal cord malignant tumors. Treatment options for...
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....
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...
Your genetic disposition to developing optical glioma may be your single-most-important risk factor. White people develop optical gliomas more frequently than black people do. If brain tumors run in your family, then you're at greater risk of...
Gliomas are primary brain cancers that begin in the glial cells, which are supportive cells in the brain. Glial cells are responsible for multiple functions, like transporting nutrients and insulating neurons. The three main types of...
You may or may not be a viable candidate for operative surgery. Only you and your physician can make that determination, based on the size, type and placement of the optic glioma as well as your age, medical history, physical condition and...
One of the most difficult aspects of dealing with an optic glioma is managing the sense of not knowing. Many optic gliomas occur in children under the age of 20. They need reassurance, as well as an explanation for what's going on and what will...
Brain tumors are one of the leading childhood cancers (after leukemia and lymphoma). Gliomas are tumors that grow in certain brain cells called astrocytes, which are primary in the function of blood and nerves in the brain. In the case of rare...
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...
Glioma tumors are a very fast moving form of brain cancer. The Glioma tumors are lethal tumors and can live on, even after surgery treatments, and then infect healthy brain tissue. These types of tumors are so aggressive that of the 20,000...
Your ophthalmologist or examining doctor may test your hearing, reflexes, visual acuity and other skills to determine whether or not you may have a brain tumor. Visual acuity tests can help determine the size and depth of the tumor by indirect...
Cancer is the result of genetic mutations that cause cells within the body to grow and divide in an out of contro. Cancer is not the result of a single mutations but rather a series of mutations that build up over time. In the brain, glial cells...
Brain tumors can be divided into two major types: primary brain tumors and secondary brain tumors, also called metastatic brain tumors. Primary brain tumors start in the brain, while secondary brain tumors originate elsewhere in the body. The...
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 stem, located between the cerebrum and the spinal cord, consists of three parts--the midbrain, the pons and the medulla. Symptoms of brain stem tumors vary according to the precise location of the tumor. The most common type of tumor in...
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....
Marijuana, also referred to as cannabis, is used medicinally to treat a number of conditions, including cancer. Marijuana and its active chemical components such as THC have many properties that can benefit cancer patients. Little is known,...
According to the National Cancer Institute (NCI), brain tumors are the most common solid tumor in children. Brain tumors in children can be benign (not cancer) or malignant (cancer is present). The most common malignant brain tumors in children...
The brain stem is located underneath the two hemispheres of the brain, linking the brain to the spinal cord. The brain stem controls blood pressure, the heartbeat, breathing and the nerves that control hearing, seeing, walking, talking, eating and...
Cancer occurs when cells in the body grow abnormally and uncontrollably. This uncontrolled growth leads to the formation of a tumor that can interfere with normal cell functions and cause the death of nearby cells. Brain cancer describes the...
The optic nerve enables people to see by translating photons of light into electrical impulses that can be interpreted by the brain. The optic nerve is the second of 12 cranial nerves that exit the brain through holes, called foramen, in the...
Curcumin is a polyphenolic compound found in a spice plant called turmeric. Because it is an antioxidant, curcumin may be able to decrease inflammation throughout the body. Scientists believe that inflammation is a part of the sequence of...
A brain tumor is an abnormal mass of cells that grows uncontrollably and expands inside the brain. An expanding tumor, which can be benign or malignant, can exert pressure on delicate tissues and interfere with brain function. A benign tumor is...
Sometimes it seems like the quest for vibrant health is one long process of renouncing your vices. At other times, it turns out what once were considered vices are now virtues. Coffee and tea are examples. Regular consumption of coffee or tea may...
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 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 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...
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...
