Brain Tumors: Classification, Symptoms, and Treatment of the Particular Disease


The intracranial tumor or the brain tumor is a growth of an abnormal tissue mass that multiplies without any control.

Though numerous brain tumors can be classified, the main divisions are metastatic and primary. Metastatic tumors are originated anywhere except the brain and migrate toward the brain through the bloodstream. Primary brain tumors can be malignant or benign.

Different Types of Benign Brain Tumors

  • Gangliocytomas- This type of tumor is rare and includes nerve cells that can be well separated. The tumor occurs mostly in young adults.
  • Chordomas- The slow-growing tumors mostly occur between the age of 50 to 60. Generally, the lower portion of the spine and the skull gets affected.
  • Glomus Jugulare- Situated at the top of the jugular vein, this tumor is situated under the base of the skull.

Different Types of Malignant Brain Tumors

An adult brain tumor can be classified into different types where 78 percent of the tumors are malignant.

  • Ependymomas- The ventricular system is lined by the ependymomas and accounts for 2 to 3 percent of all brain tumors.
  • Medulloblastomas- This type of tumor mainly rises from the cerebellum. This brain tumor generally occurs in children.
  • Astrocytomas- Half of the primary brain tumors are due to astrocytomas. They originated from the star-shaped cells that are glial. This disease may occur in any part of the brain and mostly in the cerebrum.

Other Types Of Brain Tumors

  • Rhabdoid Tumors- These are rare tumors that are highly aggressive that spreads throughout the entire nervous system. Though they mainly appear in the kidneys, the tumors can occur in multiple sites of the body. They are most prevalent in young kids but can also occur in adults.
  • Hemangiobalstomas- Generally located in the cerebellum, these are slow-growing tumors. Originated from the blood vessels, and accompanied by a cyst, the tumor can grow very large in size.

Treatment Of The Brain Tumor

  • Surgery- A patient can get relief from the pain and suffering of the tumor by getting it removed by the surgery. The neurosurgeon will operate on removing the tumor without affecting the brain tissues. Craniotomy is applied where the neurosurgeon opens the skull for obtaining access to the tumor.
  • Radiation Therapy- The high-energy rays are used for destroying the cancer cells and can help in shrinking the size of the tumors. When the tumor cannot be treated effectively through surgery, radiation therapy can be applied as an option.
  • Chemotherapy- When specific pediatric tumors need to be affected, chemotherapy can be applied. Mostly for malignant brain tumor patients, this therapy works wonders. The tumor tissues that cannot respond to the drugs can be applied with chemotherapy. Though there are side effects like nausea, suppression of immunity, scarring of the lungs, and other effects, the therapy can be used to destroy the affected cells by the tumor.


Brain tumors can be of different types and malignant and benign are the common categories among them.

The general treatments for curing tumors are surgery, chemotherapy and radiation therapy. As there are different tumors for children and adults, the treatments also differ accordingly.
