What Is Radiotherapy?
One, out of three common types, of the cancer treatments!
Radiotherapy is a medical treatment that uses controlled doses of high-energy radiation, such as X-rays, gamma rays, or particle beams, to destroy or damage cancer cells. The radiation targets the DNA inside the cells, preventing them from growing and dividing, while aiming to minimize harm to surrounding healthy tissue. It is commonly used on its own or in combination with surgery and chemotherapy to treat various types of cancer, reduce tumor size, or relieve symptoms.
How does Radiotherapy Work?
Don’t Move!
Stay Still!
The radiotherapy procedure usually begins with a planning session, where imaging scans such as CT or MRI are used to pinpoint the exact location of the tumor. Based on these images, doctors design a treatment plan that directs radiation precisely to the affected area while protecting nearby healthy tissues. During each treatment session, the patient is carefully positioned on a treatment table, and a machine called a linear accelerator delivers the radiation beams. The procedure is painless, typically lasts only a few minutes, and is repeated over several sessions depending on the treatment plan.
