Types of Brain tumors
The exact cause of brain tumors
is only rarely determinable, so
it is often hard to explain why
some people develop brain tumors,
while other don’t.
Brain
tumors are abnormal growths of
cells in the brain. They can be
primary in origin, when they
originate from the brain cells,
or they can be secondary or
metastatic, when the tumor
originates somewhere else in the
body and then spreads to the
brain through the bloodstream.
Brain tumors can be also
classified in benign and
malignant types, depending on
their behaviour: malignant
tumors tend to have a more
destructive effect on the brain
tissue than benign tumors do.
However, whether benign or
malignant, brain tumors do
always cause neurological
symptoms, due to a direct
compressive, impairing effect on
the adjacent brain tissue.
Symptoms vary from individual to
individual and can include
nausea and vomiting, headaches,
seizures, vision deficits,
hearing and speech problems,
motor and balance problems, as
well as behavioural, cognitive
and memory problems.
Although it is not possible to
determine the exact cause for
most brain cancers, there are
some known risk factors which
might play a role at least in a
few number of cases. These
include radiation exposure
(especially radiation therapy),
a family history of certain
inherited diseases of the
nervous system and immune system
impairments. Cell phone
radiation has been advocated as
a possible risk factor for the
development of brain tumors, as
well. However results are still
quite controversial and further
studies are necessary to confirm
this hypothesis.
Types of Brain tumors
So far there is no way to
prevent the development of brain
tumors, and hence early
treatment is paramount in order
to slow down, and sometimes
reverse tumor progression, as
well as to relieve neurological
symptoms. Surgery, radiation
therapy and chemotherapy are the
standard treatment options for
brain tumors. Sometimes doctors
prescribe steroids as well, to
reduce the swelling inside the
brain. Whenever possible,
surgery is the first choice
treatment, although it is not
always able to remove all cancer
cells from the tumor site. In
the last case, patients need to
be given radiation therapy or
chemotherapy after surgery, to
kill the remaining cancer cells.
Brain tumors and cure
The chance of cure depends on
many factors, including the type
and extent of the tumor, its
location within the brain,
whether it can be removed by
surgery and whether there remain
some cancer cells after surgery.
Also the age and general health
of the patient are important
predictive factors for treatment
outcome.
Patients often need to receive
different types of tests during
or after brain tumor treatment,
in order to assess the efficacy
of treatment and detect
recurrence early. Because the
cost of
treatment and tests is
generally high and can place a
large financial burden on the
patient and his or her family,
it is advisable to have it
covered by an appropriate
international health insurance
plan before the disease occurs.
