A brain cyst is a small sac that is filled with air, liquid or another type of material. Cysts are different than tumors, explains MayoClinic.com. A cyst is small, noncancerous sac. A tumor, in contrast, is caused by the abnormal growth of...
Head tumors can be either benign or noncancerous or malignant or cancerous. According to the "Merck Manuals," head tumors are generally more common in men than women. Head tumors can be either primary tumors or metastases from other tumors that...
The American Brain Tumor Association states that approximately 180,000 people are diagnosed with a brain tumor each year. Brain tumors are often slow growing, and symptoms may be intermittent at first. Symptoms commonly depend on the location of...
Patients with primary cancers of the brain or metastases from other cancers to the brain may receive radiation therapy. Radiation affects both the cancer cells and the normal brain cells; the types and magnitude of damage depends on the amount of...
A malignant brain tumor refers to a group of rapidly growing abnormal cells that spread to other parts of your body (metastasize). The American Brain Tumor Association says that a brain tumor is also considered malignant when it provokes...
According to braintumor.org, a brain tumor is an abnormal mass of tissue in which some cells grow and multiply uncontrollably, apparently unregulated by the mechanisms that control normal cells. Brain cancer can originate either within the brain...
Frontal lobe brain tumors can be cancerous or noncancerous. Both types of tumors can cause symptoms for a variety of reasons. Tumors can destroy brain cells, causing permanent brain damage and inflammation as well as placing pressure on tissues...
Brain cancer is a relatively rare type of cancer, accounting for only about 1 percent of all cancers in the United States, according to the medical care provider Cedars-Sinai. Brain cancer occurs when cells of the brain change into cells that...
A brain tumor is a mass or collection of abnormal cells that grow abnormally and out of control. Tumors that form in the brain are referred to as primary tumors. A tumor can also be initiated in tissues outside of the brain and then spread to the...
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 are the result of quickly growing abnormal cells in the brain. Primary brain tumors, which are tumors that arise from the cells that support the neurons, can be either benign or cancerous. Metastatic brain tumors, which are due to...
A brain tumor is a growth of abnormal cells occurring in the brain. There are many different types of brain tumors, each causing their own set of symptom and requiring different treatments. Brain tumors that are not cancerous are called benign...
Cancer is a disease process characterized by the out-of-control growth of abnormal cells that can invade normal body cells and tissues. Cancer in the brain causes the growth of tumors that are classified by the type of cell they invade. Brain...
A brain cyst is a noncancerous growth that contains tissue, blood, cerebrospinal fluid or minerals. The American Brain Tumor Association points out that brain cysts can cause problems if they are located in regions responsible for essential...
Cerebral tumors occur when there is an abnormal amount of cell growth in the brain or skull. There are more than 100 different types of brain tumors, but they can all be classified as either primary or secondary, which means they originate in the...
Deoxyribonucleic acid (DNA) damage in the brain can lead to uncontrolled cellular growth, resulting in brain cancer. The stereotypical lump of tissue associated with a tumor is the physical manifestation of the uncontrolled growth. Removal of the...
About 19,000 Americans will have been diagnosed with primary brain cancer in 2010, according to the National Cancer Institute. Tumors are an overgrowth of abnormal cells. These cells may be cancerous or not cancerous. Symptoms of brain tumor can...
According to the National Cancer Institute, approximately 22,020 men and women will be diagnosed with brain cancer in 2010. Brain cancer can either begin in the brain or spread from other parts of the body. These cancers are among the most...
The most common symptoms of primary and metastatic brain tumors are the same. A primary brain tumor refers to a lesion of abnormal cells that originate in the brain. A metastatic brain tumor refers to a lesion of abnormal cells that has spread to...
Each year, doctors diagnose about 2,200 children and adolescents with a primary brain tumor, according to the Lucile Packard Children's Hospital at Stanford. Primary brain tumors originate in the brain, while secondary brain tumors start elsewhere...
Brain tumors can cause serious problems because of the inherent fragility of the neurons within the brain. Because neurons are generally unable to divide and reproduce, brain cancer generally is caused by abnormal cells that come from other parts...
Brain tumors may occur at any age, but the most common brain tumors among children and teenagers are ependymomas, astrocytomas, brain gliomas, and medulloblastomas, says the American Brain Tumor Association. The symptoms of brain tumor vary...
Brain cancer can be either primary or secondary. Primary brain cancer develops in the brain while secondary develops elsewhere in the body but spreads to the brain. In the United States, over 17,000 individuals annually are diagnosed with primary...
Radiation therapy uses high-energy light rays to kill cancer cells. The radiation can be aimed at specific lesions in both the brain and body which may limit some of the damage to normal tissues. Whole or full brain radiation--where the entire...
Because chemotherapy drugs contain powerful agents designed to kill cancer cells throughout the body, they also kill healthy cells, report doctors at the American Cancer Society. Every patient reacts differently to chemotherapy. Most patients can...
A grand mal seizure, often referred to as a tonic-clonic seizure, is characterized by violent muscle spasms and a loss of consciousness. A grand mal seizure, like all seizures, occurs due to abnormal electrical activity in the brain. A person most...
A brain tumor is a mass of abnormal cells that develops within the brain tissue. The most common type of brain tumors in babies and children are medulloblastoma or astrocytoma brain tumors. According to the American Brain Tumor Association, 2,200...
Each year, approximately 2,200 children in the United States are diagnosed with a brain tumor, according to the American Brain Tumor Association. Like brain tumors in adults, many symptoms depend on the location of the tumor. Brain tumor symptoms...
Everyone knows that exercise is good for you, but researchers are now discovering that exercise can help to reduce the damage from radiation treatments on the brain and aid recovery, according to a study by Duke University published in the October...
