Brain TumorBy: Guadalupe Solis

What is a tumor ?

A tumor is an abnormal growth of body tissue.

Tumors can be cancerous (malignant) or noncancerous.

Lists Of TumorsBrain & Spinal Cord Tumors

Brain Tumors

Carcinoid Tumors

Embryonal Tumors

Islet Cell Tumors, etc…

The most dangerous tumor are the Brain Tumor. The brain tumors are dangerous because of their tendency to invade the brain, but they rarely spread outside the brain.

What is a brain tumor ?

• Brain tumor is an abnormal growth tissue in the brain.

• The tumor can either originate in the brain itself (primary brain tumor), or come from another part of the body and travel to the brain (metastatic or secondary tumor).

How Does It Happen ?

First, primary brain tumor are those that start in the brain, or near to the brain.  These can happen in the skull, in the cranial nerves, as well as in the brain membrane, pituitary gland and pineal gland.   In primary brain tumors, there is no other source of cancer or tumors within the rest of the body.

Different Types Of Tumors There are many types of brain tumors. The first way to divide brain tumors is based on whether they are primary or secondary :

Primary brain tumors are tumors that begin in the brain.

• Primary brain tumors can be divided based on what type of cell the tumor began. Some primary brain tumor types are meningioma, ependymoma, pineal tumors, germ cell tumors, etc. The name of a tumor depends in part on what kind of cell it comes from. They can also be named for the tumor location within the brain.

Secondary brain tumors are tumors that started our elsewhere in the body and spread, or metastasized, to the brain.

• For example, secondary brain tumors could have begun as breast or lung cancer.

MeningiomaWhat is Meningioma?• Meningioma are

the second most common primary neoplasm (brain tumor) of the central nervous system.

What are the risks?• The risks of

Meningioma are

EpendymomaWhat is ependymoma?• Ependymoma is a

tumor that arises from the ependyma, a tissue of the central nervous system.

The Causes • There are no known

environmental causes for ependymomas, but there have been a number of mutations in the genes in the patients that are diagnosed with the disease.

PinealomaWhat is pinealoma?• Pinealoma is a

tumor of the pineal gland.

Symptoms• Other symptoms

may include hydrocephalus, gait disturbances, and precocious puberty.

What are the risks for having brain tumors?The risks for having brain tumors are:

• Your age: Your risk of a brain tumor increases as you age

• Chemical exposure on the job: People working in certain industries may HAVE an increased risk of brain tumors, possibly because of the chemicals they're exposed to on the job.

• Family history: A small portion of brain tumors occur in people with a family history of brain tumors or a family history of genetic syndromes.

Symptoms The symptoms of brain tumors depend on tumor size, type, and location.

The Symptoms of a brain tumor are:• Headaches • Nausea or vomiting • Problems balancing

or walking• Problems with

memory
