Brain Tumor: 9 Types, Causes, and Symptoms

Brain tumors are diseases that arise as a result of abnormal tissue growth in the brain. Depending on the type, there are benign and malignant brain tumors.

The emergence of tumors in the brain can originate from the brain tissue itself (or called the primary brain tumor), can also originate from cancer in other organs that spread to the brain (secondary brain tumor).

Types of brain tumors, according to the growth location

Here are some types of benign brain tumors, according to their growth location:

  • Tumors are located on the glia tissues (tissues that bind to nerve cells and fibers) and spinal nerves. Most brain tumors that occur are a type of glioma.
  • Most of these tumors are not cancerous. This Tumor generally occurs in the membrane that protects the brain and spinal cord.
  • Tumors that occur in the blood vessels of the brain. This condition can cause partial paralysis and seizures.
  • Acoustic Neuroma is a tumor that grows on the acoustic nerve. This nerve plays a role in controlling listener and balance.
  • Adenoma pituitary. The Tumor is located on the pitted molar. These glands are located under the brain. Most of these tumor has been benign types of tumors and can affect pituitary hormones with effects throughout the body.
  • These tumors grow or are near the base of the brain. Craniopharyngioma tends to occur in children or adolescents.
  • Medulloblastoma is cancerous, and is common in children. Tumors tend to spread until the spinal cord fluid generally starts from the lower back of the brain. Although it is rare in older people, this condition may arise.
  • PNETs (primitive neuroectodermal tumors). This Tumor is cancerous, begins fetal cells in the brain. This rare Tumor can appear in any part of the brain.
  • Germ cell Tumor. This Tumor generally develops in childhood. Precisely when the testi**cles or ovaries begin to form. However, these tumors can move to other parts of the body, such as the brain.

Causes of brain tumors

Here are some conditions that are the cause of brain tumors.


About 2 percent of brain tumors are thought to be caused by obesity. There is evidence that people who are overweight have an increased risk of developing a brain tumor with meningiomas. There are also some cases in children born weighing more than 4 kilograms high risk of developing a brain tumor of pilocytic or embryonal tumors.

Hereditary factors

About 5-10 percent of brain tumors are affected by genetic or hereditary factors from their families. Although genetically inherited brain tumors are rare, there is no hurt to consult a doctor if a member of your family is diagnosed with a brain tumor. The Doctor may refer you to a genetic counselor.


Actually, brain tumors can appear at any age. Toddlers up to adolescence are susceptible to this disease. However, the risk of exposure will increase as the age increases because the brain tumor is easier to occur in the elderly, especially aged 65-75 years and above.

Other causes

  • Radiation exposure
  • People with HIV / AIDS.
