A brain tumor is an abnormal growth of cells in the brain that can be cancerous (malignant) or noncancerous (benign). Primary brain tumors originate in the brain itself, while secondary tumors spread to the brain from other areas of the body. The risks of developing a brain tumor include increasing age, chemical exposure, and family history of brain tumors or genetic syndromes. Symptoms of a brain tumor depend on its size, type, and location, and may include headaches, nausea, balance issues, and memory problems.

tumor ? Tumors can be
cancerous (malignant)
or noncancerous.

3. Lists Of Tumors

4. 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).

5. First, primary brain
How Does It tumor are those that
start in the brain, or
Happen ? 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.

6. 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.

7. Meningioma
What 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

8. Ependymoma
What 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.

9. Pinealoma
What is pinealoma?
• Pinealoma is a tumor of
the pineal gland.
Symptoms
• Other symptoms may
include hydrocephalus,
gait disturbances, and
precocious puberty.

10. 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.

11. Symptoms The
symptoms
The Symptoms of a of brain
brain tumor are: tumors
• Headaches depend
• Nausea or vomiting
• Problems balancing
on tumor
or walking size, type,
• Problems with and
memory location.
