Meningiomas are relatively common tumors occurring around the brain and spinal cord, which are usually benign and found most frequently in older women. A link between meningiomas and female hormones, particularly progesterone, has been suggested...
Meningiomas are a type of tumor that grows within the meninges, the protective tissue that covers the spinal column and brain. Approximately 90 percent of meningiomas are benign or noncancerous and are diagnosed most frequently in patients between...
A meningioma is a type of tumor that develops within the membranes that cover the brain and spinal cord, which are called the meninges. Parasagittal meningiomas form near the falx, a groove that runs along the brain from front to back, according...
A meningioma is a tumor that affects the meninges, which is the covering that surrounds your brain and spinal cord. Even if this type of tumor is benign, it can still cause problems if it presses on the brain or spinal cord nerves. The type and...
The expanding use of mobile phones causes concerns about increasing the risk of brain cancer. Scientists who conducted a large study on the long term effects of mobile phones on the brain published their findings in the "International Journal of...
The brain is covered by layers of membranes, known collectively as meninges, which function to protect the central nervous system and regulate the fluid pressure within the skull. There are three layers of meninges: the inner pia mater, the...
Calcium deposits on the brain or cranium calcification are more common than one might think. They are caused when calcium in the bloodstream is not absorbed by the body and is deposited on the brain. There can be many different causes of calcium...
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...
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...
Noncancerous and cancerous tumors may develop in the eyes. Less commonly, cancers arising elsewhere in the body can spread to the eyes. Eye tumors can affect any of the eye structures, including the optic nerve, the retina, the iris and the eye...
Piercing, pounding and throbbing headaches often make the sufferer feel like their head is in a vise. According the Centers for Disease Control and Prevention, occasional headaches strike more than 90 percent of the U.S. population. While millions...
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...
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...
One way to classify brain tumors is to assess their location in proximity to the tentorium cerebelli, a thick membrane separating the back of the brain from the cerebellum. Supratentorial tumors are found above the tentorium cerebelli, and most...
Chemo, or chemotherapy, involves the use of drugs to destroy cancer cells or stop them from multiplying, while radiation therapy is the use of high-powered radiation to destroy cancer cells. Cancer cells are more susceptible to both chemotherapy...
Neurons typically do not themselves become cancerous because they lack the ability to replicate, which is essential for cancer cells. As a result, most kinds of brain cancer result from the surrounding cells that protect, nourish and support...
Cerebral tumors are abnormal unregulated growths of cells in the cerebrum, the largest part of the brain. The cerebral hemispheres play a role in sensory perception, thought processes, language and voluntary body movement. Most of the brain's...
The American Cancer Society estimates that more than 22,000 new cases of brain and other nervous system cancers will be diagnosed among Americans in 2010 alone. Although not always malignant, brain tumors can cause problems and pose a fatal threat...
Spinal stenosis occurs when a blockage decreases the diameter of the central tunnel that descends through the bones of the spinal column. The narrowed canal can compress the nerves that comprise the spinal cord, which passes through the spinal...
Brain tumors are a mass or growth of abnormal cells in the brain, some of which are cancerous while others are not, the Mayo Clinic explains. The cause of cancerous tumors are not known, but what is clear are existing risk factors that may...
Brain cancer is a serious form of cancer that can interfere with normal brain function. The exact cause of brain cancer is not known, though different types of brain cancer form on the various parts of the brain, structures and tissue. The biggest...
Cells that express the pigment melanin are predominantly found in the skin, but these cells are also present in the meninges of the central nervous system. Meninges are layers of membranes that surround and protect the central nervous system....
Cancers of the brain and nervous system are rare but very serious as they have a poor prognosis. The majority of brain cancer cases cannot be explained by any specific underlying medical or genetic conditions, environmental factors or behaviors. A...
Cell phones use radiofrequency energy, also known as radio waves, to function. Given the ubiquity of cell phones, people have expressed concerns that the radiofrequency energy causes cancer. The National Cancer Institute acknowledges these...
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...
Human growth hormone, or HGH, is approved by the FDA to treat several conditions in children. Dr. Alan Rogol, writing in the online medical reference UpToDate, reports that HGH may be used to treat growth hormone deficiency as well as chronic...
Tamoxifen, often sold as Nolvadex, affects the body's estrogenic system. It blocks estrogen binding in the breast and promotes binding elsewhere. Doctors prescribe tamoxifen to treat breast malignancies because cancer cells need estrogen to...
Each year, nearly 20,000 people are diagnosed with brain cancer in the United States, report health officials at the National Cancer Institute. This condition, which is also known as primary brain cancer, is caused by the development of cancerous...
The American Cancer Society estimates that in 2010, more than 22,000 people in the United States will be newly diagnosed with a brain or spinal cord tumor. The exact cause of brain tumors is not understood completely, but several risk factors can...
