Q. What causes brain tumors?

Doctor Answer is medically reviewed by SecondMedic medical review team.

Answered by Secondmedic Expert

Brain tumors are caused when abnormal cells in the brain grow and divide uncontrollably. These cancerous cells can form a tumor that can damage normal brain tissue.

There are many different types of brain tumors, and the cause can vary depending on the type of tumor. Some tumors are caused by genetic abnormalities, while others may be caused by environmental factors or exposure to radiation. However, in most cases the cause is unknown.

Some possible causes of brain tumors include genetics (due to a faulty gene), radiation exposure, and a history of cancer. In some cases, viruses or other toxins may also play a role in causing brain tumors.

Brain tumors can be caused by a number of things, including genetics and environmental factors.

The most common type of brain tumor is a glioma, which is a tumor that begins in the glial cells. Glial cells are the supportive cells in the brain that help to keep the neurons (nerve cells) functioning properly. Other types of brain tumors can include meningioma (a tumor that grows on the membranes covering the brain and spinal cord), acoustic neuroma (a tumor that arises from Schwann cells that surround the nerve endings leading from the inner ear), and oligodendroglioma (a tumor that starts in oligodendrocytes, which are specialized cells that produce myelin).
