Radiation Therapy for Brain Tumors: An Overview

Radiation therapy is a common treatment for brain tumors. It uses high-energy radiation to kill cancer cells and shrink tumors. Radiation therapy can be used to treat both primary brain tumors (tumors that start in the brain) and metastatic brain tumors (tumors that have spread to the brain from other parts of the body).

How Does Radiation Therapy Work?

Radiation therapy works by damaging the DNA of cancer cells. This damage prevents the cancer cells from dividing and multiplying, which leads to tumor shrinkage. Radiation therapy can also damage healthy cells, but the goal is to deliver a dose of radiation that kills the cancer cells without causing too much damage to healthy tissue.

Types of Radiation Therapy

There are two main types of radiation therapy:

• External beam radiation therapy (EBRT) delivers radiation from a machine outside the body. EBRT is the most common type of radiation therapy for brain tumors.
• Internal radiation therapy (brachytherapy) delivers radiation from a radioactive source that is placed inside the body. Brachytherapy is less common than EBRT, but it can be used to treat certain types of brain tumors.

Side Effects of Radiation Therapy

Radiation therapy can cause a variety of side effects, including:

• Fatigue
• Hair loss
• Skin irritation
• Nausea and vomiting
• Diarrhea
• Cognitive problems
• Hearing loss

The side effects of radiation therapy depend on the dose of radiation, the type of radiation therapy, and the location of the tumor.

Effectiveness of Radiation Therapy

Radiation therapy is an effective treatment for brain tumors. It can improve survival rates and reduce symptoms. Radiation therapy is often used in combination with other treatments, such as surgery and chemotherapy.

Who Is a Candidate for Radiation Therapy?

Radiation therapy may be an option for people with:

• Primary brain tumors
• Metastatic brain tumors
• Recurrent brain tumors

The decision of whether or not to undergo radiation therapy is based on a number of factors, including the type of tumor, the stage of the tumor, and the patient’s overall health.

What to Expect During Radiation Therapy

Radiation therapy is typically given on an outpatient basis. This means that you will not need to stay in the hospital overnight. Each treatment session takes about 15-30 minutes. The number of treatment sessions will depend on the type of tumor and the stage of the tumor.

During radiation therapy, you will lie on a table and the radiation machine will be positioned around you. You will not feel any pain during the treatment.

After Radiation Therapy

After radiation therapy, you may experience some side effects. Your doctor will give you instructions on how to manage these side effects.

Radiation therapy can be an effective treatment for brain tumors. It can improve survival rates and reduce symptoms. If you are considering radiation therapy, it is important to talk to your doctor about the benefits and risks of treatment.
