A primary brain tumor is a group (mass) of abnormal cells that start in the brain. This article focuses on primary brain tumors in children.

Primary Brain Tumors
Primary brain tumors are tumors that start in the brain. There are many types and subtypes of primary brain tumors. They include gliomas, meningomas, medullablastomas, pituitary adenomas, and central nervous system lymphomas.
Primary Brain Tumors
These are tumors that originate in brain tissue.
Primary Brain Tumor Causes
Researchers have determined that both environmental and genetic factors can contribute to primary brain tumor development.
Primary brain tumor
Original source of tumor is the brain rather than other areas of the body.
Primitive
Undeveloped or in early stages of development, undifferentiated.
Primary brain tumors
Primary brain tumors originate in the brain. They represent about 1% of all cancers and 2.5% of all cancer deaths.

Primary brain tumors
The brain is made up of many different types of cells and tumors that arise from a brain cell type are termed primary brain tumors.
Primary brain tumors occur in the brain such as include the skull, brain membranes, cranial nerves, pituitary gland or pineal gland. The remaining brain tumors are secondary and it is also known as metastatic.
Primary brain tumors are classified by cell type of origin and by how malignant the cells appear when examined using histopathology techniques (histological grade).
Primary brain tumors are a diverse group of diseases that together constitute the most common solid tumor of childhood.
Primary brain tumors include any tumor that starts in the brain. Primary brain tumors can arise from the brain cells, the membranes around the brain (meninges), nerves, or glands.
Primary brain tumors can be noncancerous (benign) or cancerous (malignant). Secondary brain tumors (metastatic brain tumors) are malignant and are more common.
Primary brain tumors include any tumor that starts in the brain. Tumors may be confined to a small area, invasive (spread to nearby areas), benign (not cancerous), or malignant (cancerous).

Primary brain tumors are cancers that originate in the brain. These tumors are very different from secondary brain tumors, which originally developed elsewhere in the body and spread (metastasized) to the brain.
Primary brain tumors are more common in children than in adults. So if you notice any of these symptoms in your child make sure to see their pediatrician immediately.

Primary brain tumors are composed of abnormal types of brain cells with unregulated growth; the most common type is termed gliomas that arise from brain glial cells, but there are many other types (for example, astrocytomas, ependymomas, ...
Primary brain tumors originate in the brain or close to it, such as in the skull, brain membranes (meninges), cranial nerves, pituitary gland or pineal gland. Most brain tumors in children are primary.
In children, primary brain tumors (medulloblastoma, cystic astrocytoma) may be the cause; the midline cerebellum is the most common site of such tumors. Rarely, in children, reversible diffuse cerebellar dysfunction follows viral infections.
The most common primary brain tumors are gliomas, meningiomas, pituitary adenomas, vestibular schwannomas, and primitive neuroectodermal tumors (medulloblastomas).
In primary brain tumors cancer initially forms in the brain tissue. In secondary brain tumors the cancer has spread (metastasized) to the brain tissue from elsewhere in the body.
For patients with primary brain tumor, treatment options include a combination of chemo-, biological, radiation, or gene therapy approaches.

Anaplastic astrocytoma and glioblastoma account for approximately 38% of primary brain tumors; meningiomas and other mesenchymal tumors account for approximately 27%.
The processing of diagnosing primary brain tumors is based on examining the tissue within the tumor under a microscope. This system relies substantially on the ability of the pathologist to recognize cellular patterns.
Astrocytomas are the most common type of childhood brain tumor, and the most common type of primary brain tumor in adults. Astrocytomas are generally subdivided into high-grade, medium-grade, or low-grade tumors.
NOTE: This section describes a primary brain tumor, which is a tumor that begins in the brain. A primary brain tumor is relatively rare. A secondary brain tumor (also called a brain metastasis) is much more common.
Fifty percent of primary brain tumors are astrocytomas (made up of cells called astrocytes), while the remainder is comprised of more than ten other types. Brain tumors may be benign or malignant (cancer).
If you have a primary brain tumor, you will receive more focused radiation therapy. WRBT may also be used in people who have cancer in other areas of the body. The treatment is used to prevent brain cancer.
This summary refers to the treatment of primary brain tumors (tumors that begin in the brain).
Malignant Astrocytoma is an infiltrating, primary brain tumor, with tentacles that may invade surrounding tissue. This provides a butterfly-like distribution pattern through the white matter of the cerebral hemispheres.
PET scans are not approved to look at primary brain tumors. They can be helpful if the doctor is trying to find out if symptoms are related to a tumor or injury from treatment.
Approximately 2,200 children and adolescents in the US are diagnosed with primary brain tumors each year. Primary brain tumors start in the brain and generally do not spread outside the brain tissue.
A brain tumor that starts within the brain is known as a primary brain tumor. Often, a brain tumor grows from cells that metastasize, or spread, from a cancer elsewhere in the body.
Gliomas: One of the most common types of primary brain tumors arising from the brain tissue itself, gliomas arise from the supporting cells of the brain, the glial cells.
Primary tumor: A tumor that is at the original site where it first arose. For example, a primary brain tumor is one that arose in the brain as opposed to one that arose elsewhere and metastasized (spread) to the brain.
Medulloblastoma is a highly malignant primary brain tumor that originates in the cerebellum or posterior fossa.
At Jefferson, a multidisciplinary team is dedicated to primary brain tumors including central nervous system (CNS) lymphoma.
Glioblastoma multiforme (GBM) is the most common glioma (a type of brain cancer). It represents nearly one fourth of all primary brain tumors. This cancer starts in the glial cells, which are cells that help nerve cells work.
Metastatic brain tumors occur in about one-fourth of all cancers that metastasize (spread through the body). They are much more common than primary brain tumors. They occur in approximately 10 - 30% of adult cancers.

Primary brain tumors originate in the brain and can be non-cancerous (benign) or cancerous (malignant). But they're relatively rare. These tumors result from cancer that has started elsewhere in the body and spread (metastasized) to the brain.
