What is External Beam Radiation?
External beam radiation is a type of cancer treatment that involves using an external source to deliver high-energy X-rays or particles directly into the tumor site. This treatment is typically used for tumors located in areas where surgery would be too risky, such as close to critical organs like the brain and spinal cord. External beam radiation can also be used to reduce pain from advanced cancers, and it can help shrink large tumors before they are surgically removed. The first step in preparing for external beam radiation is creating a plan with your doctor and team of specialists that outlines the dose needed for treatments and how many sessions will be required. During each session, you will lie on a special table while specialized machines send beams of energy towards your tumor site. The exact duration of each session varies but generally lasts between 10 minutes and 30 minutes per day over several weeks or months. Most people feel minimal discomfort during this process; however some may experience fatigue or skin irritation afterwards which usually fades within days after finishing their course of treatment. The benefits associated with external beam radiation include improved survival rates, reduced risk of recurrence, less damage to healthy tissue than other forms of cancer treatments, fewer side effects compared to chemotherapy or surgery, and shorter recovery times for patients compared to more invasive techniques. It’s important to talk with your doctor about any potential risks associated with this type of therapy so you know what to expect prior to beginning treatment. Overall, external beam radiation is an effective form of cancer treatment that has helped countless individuals achieve remission or live longer lives by targeting their specific needs without causing excessive harm through surgical interventions or harsh medications.
