Radiation therapy is a common treatment for cancer that uses targeted energy to destroy or damage cancer cells while sparing as much healthy tissue as possible. Often prescribed on its own or in combination with surgery and chemotherapy, radiotherapy serves as a key component in managing cancer. Understanding what to expect and the different types of treatments available can help demystify this process and provide patients with clarity. Here’s more on radiotherapy:
Radiation Oncology for Treating Cancer
Radiation oncology is a specialized field of medicine that utilizes radiation to treat cancer. Oncologists in this field work with advanced technologies to deliver precise doses of radiation to areas affected by cancer. The goal is to eliminate cancer cells, slow their growth, or shrink tumors before surgery.
This medical specialty relies heavily on a collaborative approach. A team of specialists work with radiotherapy oncologists to develop and deliver each patient’s treatment plan. Their combined expertise makes sure treatments are safe and tailored to meet individual patient needs.
Basics of Treatments
This therapy type typically involves a few distinct steps, starting with preparation. The process begins with a consultation, during which an oncologist examines the patient and reviews medical history. If radiotherapy is deemed appropriate, the next phase involves planning.
Planning
During treatment planning, a simulation is commonly conducted to determine the best way to deliver radiation. This step often includes imaging, such as CT or MRI scans, to precisely map the treatment area. With the help of modern software, a highly accurate plan is created to direct the energy to affected tissues while preserving surrounding healthy structures.
Treating
Sessions are painless, and patients interact minimally with the equipment, which is designed for maximum precision. Most treatment courses are delivered over a series of days or weeks, depending on the individual’s diagnosis and care plan. Radiotherapy is generally noninvasive, although it may lead to temporary side effects. Some commonly reported symptoms are:
- Nausea
- Fatigue
- Skin Irritation
- Headaches
Types of Radiotherapy Treatments
Radiotherapy is not a one-size-fits-all solution. There are various types tailored to different cancers and individual conditions. Here are three common forms of radiotherapy:
Stereotactic Radiation Therapy
Stereotactic radiation therapy (SRT) delivers a high dose of radiation with submillimeter accuracy. This method is often used to target small tumors or lesions located within or near major structures, like the brain or spine. SRT is a noninvasive procedure that can often be completed in one to five sessions. Its precision minimizes exposure to surrounding tissues, making it ideal for sensitive areas.
External Beam Radiation
External beam radiation therapy (EBRT) is the most widely used form of radiation treatment. It involves using a machine called a linear accelerator to direct high-energy beams to the cancerous area. This method is highly versatile and can treat many types of cancer, including those in the breast, prostate, and lungs. Sessions are typically scheduled daily over several weeks, allowing the radiation dose to be divided into smaller, more manageable increments. This approach reduces the risk of side effects while maintaining treatment effectiveness.
Stereotactic Body Radiation Therapy
Stereotactic body radiation therapy (SBRT) is similar to SRT but is primarily used to treat tumors in regions outside of the brain, like the lungs, liver, or abdomen. SBRT delivers powerful, targeted radiation in just a few sessions, often completed within a week. With its precision, the method can effectively target tumors while avoiding damage to nearby healthy organs.
