Radiation Therapy for Brain Cancer – Side Effects, Management, and Prognosis

Overview of Radiation Therapy for Brain Cancer

Radiation therapy, also known as radiotherapy, is a common treatment option for brain cancer. It involves the use of high-energy radiation beams to target and kill cancer cells in the brain. Radiation therapy can be used as the primary treatment for brain cancer or in conjunction with surgery and/or chemotherapy.

Types of Radiation Therapy

There are two main types of radiation therapy used for brain cancer:

External Beam Radiation Therapy (EBRT): This type of radiation therapy delivers radiation from a machine outside the body. It is a standard treatment for many types of brain tumors.
Brachytherapy: In this type of radiation therapy, radioactive sources are placed directly into or next to the tumor. It allows for targeted delivery of radiation to the tumor site.

Goals of Radiation Therapy

The goals of radiation therapy for brain cancer include:

Destroying cancer cells: Radiation therapy targets and kills cancer cells, preventing them from multiplying and spreading.
Shrinking tumors: By reducing the size of tumors, radiation therapy can alleviate symptoms such as headaches, seizures, and vision problems.
Preventing regrowth: Radiation therapy aims to prevent cancer cells from regrowing after treatment, reducing the likelihood of recurrence.

Treatment Planning and Delivery

Before starting radiation therapy, a team of healthcare professionals, including radiation oncologists and medical physicists, will create a treatment plan tailored to the individual patient’s needs. The plan will outline the dose of radiation, the number of treatment sessions, and the target areas in the brain.

The radiation therapy sessions are typically carried out over several weeks, with each session lasting a few minutes. Patients may experience mild discomfort during the procedure, but the radiation itself is painless.

During treatment, patients are closely monitored to ensure the delivery of the prescribed radiation dose to the targeted areas while minimizing exposure to surrounding healthy tissue.

In recent years, advancements in radiation therapy techniques, such as intensity-modulated radiation therapy (IMRT) and stereotactic radiosurgery, have improved the precision and efficacy of treatment for brain cancer patients.

It is essential for patients undergoing radiation therapy for brain cancer to adhere to their treatment schedule and follow their healthcare provider’s recommendations to maximize the benefits of therapy and minimize potential side effects.
