What is a brain tumor? It is a mass or growth of abnormal cells in your brain. Many different types of brain tumors exist. Some brain tumors are noncancerous (benign), and some brain tumors are cancerous (malignant). Brain tumors can begin in your brain (primary brain tumors), or cancer can begin in other parts of your body and spread to your brain (secondary, or metastatic, brain tumors).
How quickly a brain tumor grows can vary greatly. The growth rate as well as location of a brain tumor determines how it will affect the function of your nervous system. The treatment options depend on the type of brain tumor you have, as well as its size and location.
Over 120 different types of brain tumors have been identified, making universally effective treatments complicated. Both malignant and benign tumors can be life-threatening. The average survival rate for all malignant brain tumor patients is 34.2 percent.
Primary brain tumors
Primary brain tumors originate in your brain. They can develop from your:
Primary tumors can be benign or cancerous. In adults, the most common types of brain tumors are gliomas and meningiomas.
Secondary brain tumors
Secondary brain tumors make up the majority of brain cancers. They start in one part of the body and spread, or metastasize, to the brain. The following can metastasize to the brain:
Secondary brain tumors are always malignant. Benign tumors don’t spread from one part of your body to another.
The signs and symptoms of a brain tumor vary greatly and depend on the brain tumor’s size, location and rate of growth.
General signs and symptoms caused by brain tumors may include:
Diagnosis of a brain tumor begins with a physical exam and a look at your medical history. The physical exam includes a very detailed neurological examination. The doctor may also evaluate your:
Your doctor may order more tests for examination:
The treatment of a brain tumor depends on:
The most common treatment for malignant brain tumors is surgery. The goal is to remove as much of the cancer as possible without causing damage to the healthy parts of the brain. While the location of some tumors allows for easy and safe removal, other tumors may be located in an area that limits how much of the tumor can be removed. Even partial removal of brain cancer can be beneficial.
Risks of brain surgery include infection and bleeding. Clinically dangerous benign tumors are also surgically removed. Metastatic brain tumors are treated according to guidelines for the type of original cancer.
Surgery can be combined with other treatments, such as radiation therapy and chemotherapy. Physical therapy, occupational therapy, and speech therapy can help you to recover after neurosurgery.
