Brain tumor radiation therapy is a medical treatment that uses high-energy radiation to destroy or damage cancerous cells in the brain. The goal is to target and eliminate tumor cells while minimizing harm to the surrounding healthy tissues. This therapy can be delivered using various advanced techniques, such as stereotactic radiosurgery or external beam therapy.
This treatment is beneficial for individuals diagnosed with primary brain tumors or metastatic brain tumors that have spread from other parts of the body. It is often used when surgery is not feasible, as an adjunct to surgery, or in combination with chemotherapy to enhance treatment efficacy.
Several types of radiation therapy are used to treat brain tumors, including:
Radiation therapy works by damaging the DNA of tumor cells, which inhibits their ability to grow and divide. Over time, the damaged cells die, and the tumor shrinks. The treatment is carefully planned to maximize its effectiveness while protecting critical brain structures.
Side effects vary depending on the type and duration of therapy but may include:
Your healthcare team will discuss potential side effects and provide strategies to manage them effectively.
The planning process begins with a detailed imaging study, such as an MRI or CT scan, to map the tumor's location, size, and shape. Advanced software is then used to create a personalized treatment plan that ensures precise delivery of radiation while minimizing exposure to healthy tissues.
The duration of treatment varies depending on the type and stage of the tumor. For instance, stereotactic radiosurgery may require only one to five sessions, while external beam radiation therapy typically involves daily sessions over several weeks.
No, the therapy itself is painless. However, some patients may experience discomfort from lying still during the procedure. If necessary, your care team can provide supportive measures to ensure comfort during treatment.
The effectiveness of radiation therapy depends on various factors, including the type, size, and location of the tumor. While it may not always provide a cure, it can significantly reduce tumor size, relieve symptoms, and improve quality of life. In some cases, it is part of a curative approach in combination with other treatments.
After completing treatment, patients will have follow-up appointments to monitor their progress through imaging studies and medical evaluations. Supportive care is also provided to manage any lingering side effects and address recovery needs.
