What Is Prostate Radiotherapy?

Definition of Prostate Radiotherapy

Prostate radiotherapy, also known as radiation therapy, utilizes targeted radiation to kill cancer cells in the prostate gland. It works by damaging the DNA of these cancer cells, preventing them from dividing and growing further. By focusing radiation directly on the prostate gland, the aim is to eradicate or shrink the tumor while minimizing damage to surrounding healthy tissues.

Purpose of Prostate Radiotherapy

The primary purpose of prostate radiotherapy is to cure or control prostate cancer. It is used to treat localized prostate cancer, where the cancerous cells are confined to the prostate gland and have not spread to other areas of the body. Radiotherapy can also be used as a palliative treatment for advanced prostate cancer, aiming to relieve symptoms and improve quality of life.

How Prostate Radiotherapy Works

Prostate radiotherapy works by delivering a prescribed dose of radiation to the prostate gland using a variety of techniques. These techniques include external beam radiotherapy, brachytherapy, intensity-modulated radiotherapy (IMRT), image-guided radiotherapy (IGRT), and stereotactic body radiotherapy (SBRT). The choice of technique depends on various factors such as the stage of cancer, the patient's overall health, and the expertise of the healthcare team.

External Beam Radiotherapy

External beam radiotherapy involves delivering radiation to the prostate gland from outside the body using a machine called a linear accelerator. This machine directs high-energy X-rays or protons precisely at the tumor, minimizing radiation exposure to nearby healthy tissues. The course of treatment typically lasts several weeks, with daily sessions scheduled from Monday to Friday.


Brachytherapy is a type of radiotherapy where small radioactive seeds or pellets are implanted directly into the prostate gland. These seeds emit radiation over time, effectively destroying the cancer cells. This technique is often used for low- to intermediate-risk prostate cancer and can be done on an outpatient basis with minimal discomfort.

Intensity-Modulated Radiotherapy (IMRT)

Intensity-modulated radiotherapy (IMRT) is a highly precise and advanced form of external beam radiotherapy. It uses computer-controlled technology to deliver radiation in varying intensities and angles, allowing for greater tumor targeting and sparing nearby healthy tissues. IMRT is particularly effective for complex-shaped tumors or for cases where the prostate gland is close to vital structures, such as the bladder or rectum.

Image-Guided Radiotherapy (IGRT)

Image-guided radiotherapy (IGRT) is a technique that involves the use of real-time imaging during radiotherapy sessions. It allows for precise targeting of the prostate gland, as the position of the tumor may vary from session to session due to organ movement or changes in bladder or rectum filling. With IGRT, imaging is performed before each treatment session to ensure accurate tumor targeting and minimize radiation exposure to surrounding healthy tissues.

Stereotactic Body Radiotherapy (SBRT)

Stereotactic body radiotherapy (SBRT) is a specialized technique that delivers high-dose radiation to the prostate gland in a small number of treatment sessions. SBRT uses advanced imaging techniques and computer modeling to precisely target the tumor while minimizing radiation exposure to nearby organs. It is an effective option for patients who prefer a shorter duration of treatment or are unable to tolerate longer courses of radiotherapy.

Preparing for Prostate Radiotherapy

Before undergoing prostate radiotherapy, it is essential to consult with a healthcare professional specializing in radiation oncology. During this consultation, the doctor will evaluate your medical history, conduct a physical examination, and may order additional tests or imaging to assess the stage and extent of the cancer. This information will help determine the most appropriate radiotherapy technique and develop an individualized treatment plan.

Pre-treatment assessments and tests commonly performed before prostate radiotherapy may include blood tests, imaging studies (such as CT scans or MRI), and a simulation session. The simulation session involves the creation of a treatment plan and precise mapping of the treatment area using CT scans or specialized imaging techniques. This allows the radiation oncology team to determine the optimal position for treatment delivery and minimize radiation exposure to nearby healthy tissues.

Planning for Treatment Sessions

Once the treatment plan has been developed, you will be scheduled for a series of treatment sessions. The number and duration of these sessions will vary depending on the chosen radiotherapy technique, the stage of cancer, and the overall treatment plan. Your healthcare team will provide specific instructions on how to prepare for each session, including any dietary restrictions, medication guidelines, and how to care for your overall well-being during the treatment period.

Step-by-step Process of Prostate Radiotherapy Treatment

The process of prostate radiotherapy treatment generally involves several steps. First, the patient is positioned on a treatment table in the exact position determined during the simulation session. The treatment machine is then positioned and calibrated based on the treatment plan. Once everything is set up, the machine delivers the prescribed radiation dose to the prostate gland, which typically takes a few minutes. Throughout the session, the healthcare team will monitor you from outside the treatment room, ensuring your safety and comfort.
