What is brain cancer?

Brain cancer happens when normal cells in the brain change into abnormal cells and grow out of control. There are different types of brain cancer. Some types grow very slowly. Others grow much faster.

As brain cancer grows, it can spread into normal parts of the brain. It can also cause swelling in the brain. These can cause symptoms.

What are the symptoms of brain cancer?

Often, one of the first symptoms of brain cancer is a seizure. Seizures are caused by abnormal electrical activity in the brain. A seizure can cause a person to:

Suddenly have trouble speaking or understanding
Stare off into space
Lose control of an arm or a leg
Pass out
Stiffen and then have jerking movements of the arms or legs
Lose muscle control throughout the body

Other symptoms of brain cancer can include:

Headache, often with nausea or vomiting
Vision changes, such as double vision or a loss of vision
Memory problems or having trouble thinking clearly
Weakness or numbness in the arms or legs
Personality changes

These symptoms can also be caused by conditions that are not brain cancer. But you should let your doctor or nurse know if you have any of these symptoms.

Is there a test for brain cancer?

Yes. Doctors use imaging tests such as CT or MRI scans to help diagnose brain cancer. These tests create images of your brain and can show tumors or abnormal growths.

After an imaging test, your doctor might follow up with another test called a biopsy. During a biopsy, a doctor takes a very small sample of the brain tissue. They will look at the sample under a microscope to see if cancer is present. Other times, your doctor might recommend surgery right away. With surgery, doctors can try to remove a tumor or growth, and can take a tissue sample for testing at the same time.

The right treatment for you will depend a lot on the type of brain cancer you have, and how fast the cancer is growing. Your treatment will also depend on your symptoms, age, and other health problems.

How is brain cancer treated?

Different treatments can include:

Surgery – During surgery, doctors try to remove as much of the cancer as possible. Often, brain cancer cannot be cured with surgery, but surgery might reduce symptoms and help people live longer. On the other hand, surgery can also lead to more symptoms or problems. This is because healthy parts of the brain can be damaged during surgery. How much cancer can be removed depends on where the cancer is in the brain.
Radiation therapy – Radiation kills cancer cells. People might receive radiation therapy after surgery, or when surgery is not possible.
Chemotherapy – Chemotherapy is the medical term for medicines that kill cancer cells or stop them from growing. People might receive these medicines during or after radiation therapy to keep the cancer from growing, spreading, or coming back.
Electrical device – In some cases, people with certain kinds of brain cancer might be able to try treatment with a device they wear on their head. The device creates a special type of electricity, which might help slow down cancer growth.

People with brain cancer also receive treatment for any symptoms they have. For example, people might take medicines to control seizures.
