What is External Beam Radiation Therapy (EBRT)?
External Beam Radiation Therapy (EBRT) is a common method used to treat various types of cancer. It involves directing high-energy beams, such as X-rays or protons, from outside the body to target and destroy cancer cells. The precision of EBRT allows it to focus on the tumor while minimizing damage to surrounding healthy tissues.
How Does EBRT Work?
EBRT works by damaging the DNA of cancer cells, which inhibits their ability to reproduce and grow. Over time, the damaged cancer cells die off, and the tumor shrinks. The treatment is typically delivered in multiple sessions over several weeks to allow healthy cells time to repair and recover between doses.
What Are the Side Effects of EBRT?
While EBRT aims to minimize damage to healthy tissues, some side effects may occur, depending on the treatment area. Common side effects include:
Fatigue
Skin irritation and redness
Swelling and inflammation
Hair loss in the treatment area
Changes in appetite
Most side effects are temporary and can be managed with the help of the healthcare team.
Consultation: Meeting with a radiation oncologist to discuss the treatment plan.
Simulation: Using imaging techniques like CT or MRI to map out the exact location of the tumor.
Treatment Planning: Creating a customized plan that defines the dose and angles of the radiation beams.
Treatment Sessions: Typically, a patient undergoes several sessions, each lasting a few minutes.
What Should Patients Expect During EBRT?
During each treatment session, the patient will lie on a treatment table while the radiation machine moves around them to deliver the beams. The procedure is painless, and the patient can usually resume normal activities shortly after each session.
Non-invasive and painless
High precision in targeting tumors
Can be combined with other treatments like
chemotherapy or
surgery Short recovery time
Effective for a wide range of cancers
Conclusion
External Beam Radiation Therapy is a vital tool in the fight against cancer, offering a non-invasive and highly precise treatment option. With ongoing advancements in technology, EBRT continues to improve in effectiveness and safety, providing hope and better outcomes for cancer patients worldwide.
