While undergoing radiation therapy can be emotionally and physically challenging, it's important to remember that it serves a vital purpose in the fight against cancer. In this article, we'll explore the various aspects of radiation therapy, from understanding the treatment³ to coping with the emotional stress that may accompany it⁵. With this knowledge, we hope to provide support and guidance, making this journey just a little bit easier for you and your loved ones.

Understanding Radiation Therapy

Radiation therapy, or radiotherapy, is a treatment method that uses high-energy rays or particles to target cancer cells in your body¹. The aim of this treatment is to damage or destroy the cancer cells, thus preventing them from growing or spreading. Radiation therapy can be utilized as a standalone treatment or combined with other treatments like surgery, chemotherapy, or immunotherapy to improve the chances of a successful outcome².

The fundamental idea behind radiation therapy is to maximize damage to cancer cells while minimizing harm to the surrounding healthy tissues. To achieve this balance, medical professionals use various techniques such as³:

• Simulation and planning: Before starting radiation treatment, a thorough planning process takes place to accurately identify the target area in your body needing radiation. This often involves imaging studies like CT scans, MRIs, or PET scans, to help provide detailed information about the tumor size, shape, and location.
• Customized treatment devices: Special devices may be created, such as masks or molds, to help you stay still during the treatment and reduce the risk of harming healthy tissue.
• Daily positioning: Your radiation therapy team will ensure that you are precisely positioned before each treatment session to accurately direct the radiation to the target area.
• Advanced radiation delivery systems: There are various radiation delivery technologies used to treat different types of cancer or tumor locations. These technologies, such as intensity-modulated radiation therapy (IMRT) or stereotactic body radiation therapy (SBRT), allow for more precise delivery of radiation.

Close monitoring is crucial during radiation therapy. Your healthcare team will schedule regular check-ins to assess your response to the treatment and customization of the therapy as needed. These appointments are a valuable opportunity to discuss any concerns or side effects you may be experiencing⁴.

It's essential to understand that each individual's radiation therapy experience is unique. Factors such as cancer type, its location and stage, your general health, and other ongoing treatments play a role in determining the specific therapy plan for you⁵. Being open and communicative with your healthcare team will help you understand and manage your radiation therapy journey more effectively⁶.

Types of Radiation Therapy

There are several types of radiation therapy, each with its unique set of procedures, goals, and side effects¹. Your healthcare team will thoroughly assess your specific situation and recommend one or a combination of therapies that best align with your treatment plan.

Here are some common types of radiation therapy:

• External Beam Radiation Therapy (EBRT) is the most common form of radiation therapy¹. It involves utilizing a machine called a linear accelerator, which guides high-energy beams to the tumor from outside your body. The radiation is accurately directed at the tumor while preserving healthy tissue².
• Intensity-Modulated Radiation Therapy (IMRT) is a more sophisticated form of EBRT¹. It utilizes advanced computer algorithms to plan and deliver precise, varying radiation doses to the tumor. This technique allows for better preservation of nearby healthy tissues and can potentially reduce side effects².
• Stereotactic Body Radiotherapy (SBRT), also known as Stereotactic Ablative Radiotherapy (SABR), is a highly accurate external radiation delivery method¹. It's often used for small, early-stage tumors, and can deliver very high doses of radiation in fewer treatment sessions than traditional EBRT³.
• Proton Therapy is another form of external radiation treatment that employs protons, rather than X-ray photons used in other EBRT methods¹. Proton therapy can be highly precise in delivering radiation, resulting in reduced damage to surrounding healthy tissues. However, it's not available everywhere due to the specialized equipment and expense involved².
• Brachytherapy is an internal form of radiation therapy where small radioactive sources are implanted directly into or near the tumor¹. This allows for higher doses of radiation to be delivered more locally to the cancer cells, with reduced exposure to healthy tissue².
• Systemic Radiation Therapy utilizes radioactive substances, like radiopharmaceuticals, that are ingested or injected into the body¹. This method allows the radiation to circulate throughout the body to target cancer cells or metastases².

It's crucial to discuss with your healthcare team the specific type of radiation therapy recommended for you, and any potential side effects or risks associated with the procedure⁴. By understanding the treatment options available to you, you'll be better prepared for your healing journey and better able to cope with any challenges that may arise⁵⁶.
