What Is An Astrocytoma?

Astrocytoma is a malignant brain tumor that arises from astrocytes. This type of tumor is "graded I to IV" based on how normal or abnormal the cells look. Low-grade astrocytomas are usually slow-growing and localized, while high-grade astrocytomas grow at a rapid pace and require different treatment. Most astrocytomas found in adults are high-grade, and most found in children are low-grade. They typically appear in the largest part of the brain, the cerebellum, but can appear in other parts of the brain and nervous system; this includes the cerebrum, brainstem, and spinal cord.

What Are The Symptoms Of An Astrocytoma?

Symptoms include:

  • Convulsiones
  • Headaches
  • Speech difficulty
  • Memory loss
  • Loss of appetite
  • Changes in behavior and personality

What Causes An Astrocytoma?

Astrocytomas arise from astrocytes; star-shaped glial cells of the central nervous system. Tumors can spread to the brain from other parts of the body.

What Are The Treatments For Astrocytoma?

The treatment options include:

  • Surgery; this is generally the primary option used for removing a malignant tumor with a goal of removing as much of the tumor as possible without damaging normal brain tissue.
  • Radiation; this is used for killing off tumor cells and limiting the growth of the tumor
  • Chemotherapy; this involves the use of medications that stop the growth of the tumor and can be given orally, through an IV, or placed at the site of your tumor through a shunt.
