Title: Glioma Brain Cancer-Types, Symptoms & Causes


1
Glioma Brain Cancer Types, Symptoms Causes
2
Glioma brain cancer is a type of tumor that
originates in the glial cells of the brain or
spinal cord. These tumors can vary in severity
and aggressiveness, and they are classified based
on the specific type of glial cell involved.
Gliomas can cause a range of symptoms depending
on their location and size, and treatment
typically involves a combination of surgery,
radiation therapy, and chemotherapy.

Types Of Glioma Brain Cancer
  • Astrocytoma
  • Oligodendroglioma
  • Glioblastoma
  • Ependymoma

4
Astrocytoma
Astrocytoma originates from astrocytes,
supportive cells surrounding neurons, spreading
through the spine and brain when merging with
healthy tissues. This blending makes them
challenging to remove, especially if high-grade.
Oligodendroglioma
Oligodendrogliomas, a type of glioma, develop
from oligodendrocytes, which shield neurons. They
are rare, emerging within the cerebrum, and
typically grow slowly without spreading to nearby
brain tissue. Occurring most often in middle-aged
individuals, they are classified as stage 2 or
stage 3 glioma brain cancer.
5
Glioblastoma
Glioblastoma is a highly aggressive type of
glioma brain cancer. It arises from glial cells,
particularly astrocytes, and is characterized by
its rapid growth and invasive nature.
Glioblastomas are the most common and malignant
primary brain tumors in adults.
Ependymoma
Ependymoma is a type of glioma originating from
ependymal cells lining the fluid-filled spaces in
the brain and spinal cord. Classified into stages
1 through 3, ependymomas vary in severity based
on factors such as tumor size and location.
6
Symptoms Of Glioma Brain Cancer
  • Numbness
  • Seizures
  • Headaches
  • Speech problems
  • Loss of vision
  • Dizziness
  • Weakness in the arms, legs, or face
  • Personality changes

7
Causes Of Glioma Brain Cancer
  • Genetic mutations Changes in certain genes, such
    as alterations in tumor suppressor genes or
    oncogenes, can lead to uncontrolled cell growth
    and the formation of gliomas.
  • Exposure to radiation Previous exposure to
    ionizing radiation, such as radiation therapy for
    other cancers or exposure to radiation in the
    environment, may increase the risk of developing
    gliomas.
  • Family history In some cases, individuals with a
    family history of brain tumors or certain genetic
    syndromes associated with an increased risk of
    brain cancer may have a higher likelihood of
    developing gliomas.
  • Age Gliomas can occur at any age, but they are
    more common in older adults, with the risk
    increasing with age.

8
  • Environmental factors Certain environmental
    factors, such as exposure to certain chemicals or
    toxins, may play a role in the development of
    gliomas, although specific associations are not
    well-established.
  • Immune system disorders Conditions that affect
    the immune system, such as HIV/AIDS or conditions
    that cause chronic inflammation, may increase the
    risk of glioma development.
  • Viral infections Some research suggests a
    possible link between certain viral infections,
    such as cytomegalovirus (CMV) or Epstein-Barr
    virus (EBV), and an increased risk of glioma
    development, although more studies are needed to
    confirm this association.
