2. The Brain Tumor
A brain tumor is a mass or growth of abnormal cells in your brain. We have many
different types of brain tumors. Some brain tumors are noncancerous, and some
brain tumors are cancerous. Brain tumors can begin in your brain which is one
main part that makes up the Central nervous system and cancer can begin in other
parts of your body and spread to your brain as secondary brain tumors.
How quickly a brain tumor grows can vary greatly. The growth rate as well as the
location of a brain tumor determines how it will affect the function of your nervous
system. The tumor arises from brain tissue. How serious is a Brain tumor?Brain
tumors are dangerous because they can put pressure on healthy parts of the brain
or spread into those areas. They can cause problems if they block the flow of fluid
around the brain, which can lead to an increase in pressure inside the skull.
Primary brain tumors originate in the brain itself or in tissue close it, such as in the
brain covering membranes(meninges), Cranial nerves, pituitary gland or pineal
gland. They begin when normal cells develop change (mutations) in their DNA. The
mutation tells the cells to grow and divide rapidly and to continue living when
healthy cells would die.
The results is a mass of abnormal cells, which forms a tumor. The most common
brain tumor that attacks the crutual part of the brain is the meningioma brain tumor.
A meningioma is a tumor that arises from the meninges — the membranes that
surround the brain and spinal cord. Although not technically a brain tumor, it is
included in this category because it may compress or squeeze the adjacent brain,
nerves and vessels. Meningioma is the most common type of tumor that forms in
the head.
Most meningiomas grow very slowly, often over many years without causing
symptoms. But sometimes, their effects on nearby brain tissue, nerves or vessels
may cause serious disability. Meningiomas occur more commonly in women and
are often discovered at older ages, but they may occur at any age. Because most

do not always require immediate treatment and may be monitored over time.
Signs and symptoms of a meningioma typically begin gradually and may be very
subtle at first. Depending on where in the brain or, rarely, spine the tumor is
situated, signs and symptoms may include: Changes in vision, such as seeing
double or blurriness, Headaches, especially those that are worse in the morning,
Hearing loss or ringing in the ears, Memory loss, Loss of smell Seizures Weakness
in your arms and Language difficulty.
In adults, primary brain tumors are much less common than are to secondary brain
tumors, in which cancer begins elsewhere and spreads to the brain. Secondary
brain tumors most often occur in people who have a history cancer. Treatment for
a brain tumor depends on the type, size and location of the tumor as well as your
overall health and your preferences. It can be solved through surgery, radiation
therapy and chemotherapy and others.
