Brain cancer

These two types are equally numerous in the brain as a whole, although glial cells outnumber neurons roughly 4 to 1 in the cerebral cortex. Glia come in several types, which perform a number of critical functions, including structural support, metabolic support, insulation, and guidance of development. Primary tumors of the glial cells are called gliomas and often are malignant by the time they are diagnosed.

Cancer-Fighting Foods What tests do doctors use to diagnose brain cancer? The initial test is an interview that includes a medical history and physical examination of the person by a health-care provider. Brain cancer results of this interaction will determine if other specific tests need to be done.

The most frequently used test to detect brain cancer is a CT Brain cancer computerized tomography. This test resembles a series of X-rays and is not painful, although sometimes a dye needs to be injected into a vein for better images of some internal brain structures. Another test that is gaining popularity because of its high sensitivity for detecting anatomic changes in the brain is MRI magnetic resonance imaging.

This test also shows the brain structures in detail better than CT. If the tests show evidence tumors or abnormalities in the brain tissue of brain cancer, then other doctors such as neurosurgeons and neurologists that specialize in treating brain ailments will be consulted to help determine what should be done to treat the patient.

Occasionally, a tissue sample biopsy may be obtained by surgery or insertion of a needle to help determine the diagnosis. What is the treatment for brain cancer? A treatment plan is individualized for each brain cancer patient. Patients should discuss treatment options with their health-care providers.

Surgery, radiation therapyand chemotherapy are the major treatment categories for most brain cancers. Individual treatment plans often include a combination of these treatments. Surgical therapy attempts to remove all of the tumor cells by cutting the tumor away from normal brain tissue.

This surgery that involves opening the skull craniotomy is often termed invasive surgery to distinguish it from noninvasive radiosurgery or radiation therapy described below.

Some brain cancers are termed inoperable by surgeons because attempting to remove the cancer may cause further brain damage or death. However, a brain cancer termed inoperable by one surgeon may be considered operable by another surgeon. Patients with a diagnosis of an inoperable brain tumor should consider seeking a second opinion before surgical treatment is abandoned.


Radiosurgery is a nonsurgical procedure that delivers a single high dose of precisely targeted radiation using highly focused gamma-ray or X-ray beams that converge on the specific area or areas of the brain where the tumor or other abnormality is located, minimizing the amount of radiation to healthy brain tissue.

Equipment used to do radiosurgery varies in its radiation source; a gamma knife uses focused gamma rays, and a linear accelerator uses photons, while heavy-charged particle radiosurgery uses a proton beam.

Tomotherapy is a type of radiotherapy in which radiation is delivered in a highly precise and individualized manner that minimizes radiation exposure to healthy tissue; it has also been used to treat brain cancer.

Chemotherapy attempts to destroy tumor cells using chemicals drugs that are designed to destroy specific types of cancer cells. There are many chemical agents used; specific drug therapies are numerous, and each regimen is usually designed for the specific type of brain cancer and individualized for each patient.

For example, bevacizumab Avastin is a drug approved for treatment of glioblastomas glioblastoma multiforme. Chemotherapy can be administered intrathecally into the cerebrospinal fluid by a spinal tap or through a surgically placed permanent reservoir under the scalp attached through a sterile tubing placed into the fluid-containing chambers in the brainby IV administration, and biodegradable chemically impregnated polymers.

All treatments attempt to spare normal brain cells. Other treatment options may include hyperthermia heat treatmentsimmunotherapy immune cells directed to kill certain cancer cell typesor steroids to reduce inflammation and brain swelling.

These may be added on to other treatment plans. Clinical trials treatment plans designed by scientists and physicians to try new chemicals or treatment methods on patients can be another way for patients to obtain treatment specifically for their cancer cell type.

Clinical trials are part of the research efforts to produce better treatments for all disease types. Stem cell treatments for brain and brain stem cancers and other conditions may be available, because research with patients is ongoing using these potential therapies. The best treatment for brain cancer is designed by the team of cancer specialists in conjunction with the wishes of the patient.

Metastasis, Stages of Cancer, and More Are there any home remedies for brain cancer? There are many home remedies that make claims of being effective in treating brain cancer and many other cancers. Most are nutrition or supplements like herbs, fish oils, chokeberry, and many others.

Most have little or no research data to support their claims.A brain tumor is a collection, or mass, of abnormal cells in your brain. Your skull, which encloses your brain, is very rigid.

Any growth inside such a restricted space can cause problems. Brain. Types of brain cancer. Every brain cancer patient is different. The cancer experts at Cancer Treatment Centers of America ® (CTCA) have extensive experience in properly staging and diagnosing the disease, and developing a treatment plan that's tailored to your specific type of brain cancer..

Primary brain tumors are tumors that form from cells within the brain. Brain tumors are abnormal growths of cells in the brain.. Although such growths are popularly called brain tumors, not all brain tumors are cancer. Cancer is a term reserved for malignant tumors. There are an estimated , cases of brain tumors in the United States alone every year.

These tumors can be cancerous or noncancerous, and they can sometimes begin in the brain. However, they can also be a result of cancer that has spread from other parts of the body into the brain and its surrounding tissues.

There are approximately 23, new brain cancer diagnoses each year in the U.S. These brain masses develop when abnormal cancer cells accumulate in one area—in this case, the brain.

Primary brain tumors originate in the cells and tissues that make up the brain and central nervous system. Medical. Not all brain tumors cause symptoms, and some (such as tumors of the pituitary gland) are often not found unless a CT scan or MRI is done for another reason.

The symptoms of brain cancer are.
