Question

what is radiation therapy

Answer 1

Radiation therapy (also called radiotherapy) uses radiation, such as high-energy x-rays, gamma rays, electron beams or protons, to kill or damage cancer cells and stop them from growing and multiplying. Radiation therapy is a safe and effective treatment for many types of cancer. It involves the controlled application of radiation to cancers anywhere in the body. Cancerous cells are more susceptible to radiation than healthy, non-cancerous cells.

Exposure to radiation kills cancerous cells and prevents them from growing and/or spreading to other parts of the body. Healthy, non-cancerous cells are much better at recovering from exposure to radiation.

Radiation oncology teams tailor treatment plans for individual patients to ensure each person’s needs are met. This targeted delivery allows the goals of treatment to be better achieved – whether these are to improve survival, cure the patient or relieve symptoms such as pain. Focusing the radiation on the area to be treated reduces the impact of treatment on healthy areas of the body, limiting side effects and preserving quality of life.

There are two main types of radiation therapy: External Beam Radiation Therapy (EBRT) and Brachytherapy.
