Radiation therapy is one of the most common cancer treatments that uses high-energy radiation, such as X-rays, to destroy cancer cells or stop them from growing. It works by damaging the DNA of cancer cells, preventing them from dividing and ultimately causing them to die. In addition to treating cancer, radiation therapy can also help relieve symptoms caused by cancer.
The effects of radiation therapy are not immediate. After treatment begins, cancer cells gradually accumulate DNA damage until they eventually die. This process may take several days to several weeks after the start of treatment, and cancer cells may continue to die for weeks or even months after the course of radiotherapy has been completed.
If you are looking for recommended radiation therapy for cancer in Jakarta or Tangerang, Mandaya Royal Hospital Puri is an excellent choice. The hospital is equipped with advanced radiotherapy technology and supported by experienced radiation oncologists who develop personalized treatment plans based on each patient’s cancer type, location, and stage.

Types of Radiation Therapy Available at Mandaya Royal Hospital Puri
Mandaya Royal Hospital Puri provides several types of radiation therapy tailored to each patient’s cancer type, tumor location, disease stage, and overall condition. In general, two main types of radiotherapy are commonly used:
1. External Beam Radiation Therapy (EBRT)
External Beam Radiation Therapy (EBRT) uses a machine outside the body to precisely deliver high-energy radiation to the cancer site. This is the most commonly used form of radiation therapy for treating various types of cancer.
EBRT is commonly used to treat cancers of the head and neck, breast, lung, colon and rectum, and prostate. The goal is to destroy cancer cells while minimizing radiation exposure to the surrounding healthy tissues.
2. Brachytherapy
Brachytherapy is a form of internal radiation therapy in which radioactive sources, such as seeds, wires, rods, or specialized applicators, are placed as close as possible to the tumor, and in some cases directly inside the tumor. This approach allows a high radiation dose to be delivered directly to the cancer while limiting exposure to nearby healthy tissue.
Brachytherapy is commonly used to treat cervical, uterine, vaginal, rectal, eye, and certain head and neck cancers. It may also be used for breast, brain, skin, anal, esophageal, lung, bladder, and prostate cancers when clinically indicated.
In some cases, brachytherapy is combined with external beam radiation therapy. EBRT treats a broader area surrounding the tumor, while brachytherapy delivers an additional focused radiation boost to the primary tumor, improving treatment effectiveness.
Advanced Radiation Therapy Technologies at Mandaya Royal Hospital Puri
1. Elekta Versa HD Linear Accelerator (LINAC)
For external beam radiation therapy, Mandaya Royal Hospital Puri utilizes the Elekta Versa HD Linear Accelerator (LINAC), an advanced radiotherapy system capable of delivering radiation with submillimeter precision. The system features Stereotactic Radiosurgery (SRS) and Stereotactic Body Radiation Therapy (SBRT) technologies, enabling highly accurate tumor targeting while minimizing radiation exposure to surrounding healthy tissues.

Key advantages of the Elekta Versa HD include:
- Submillimeter radiation accuracy for highly precise tumor targeting.
- Advanced SRS and SBRT technology for delivering highly focused, high-dose radiation.
- Ability to treat multiple tumor targets in a single treatment session.
- Integrated 4D Image-Guided Radiotherapy (4D IGRT) for real-time tumor tracking, including tumors that move during breathing.
- Better protection of healthy tissues surrounding the tumor.
- Potentially fewer treatment sessions for selected patients, depending on clinical indications.
- More comfortable and effective treatment through advanced imaging and targeting technology.
2. Flexitron Brachytherapy System
For brachytherapy, Mandaya Royal Hospital Puri uses the Flexitron Brachytherapy System, an advanced brachytherapy platform also utilized by leading cancer centers worldwide, including MD Anderson Cancer Center (USA), National Cancer Centre Singapore, University of Erlangen (Germany), and Medical University AKH Vienna (Austria).

The system uses High Dose Rate (HDR) Afterloading technology, allowing radioactive sources to be positioned precisely within or near the tumor to deliver high-dose radiation directly to the cancer. This approach maximizes radiation delivery to the tumor while minimizing exposure to nearby healthy tissues.
Advantages of the Flexitron Brachytherapy System include:
- HDR Afterloading technology for highly accurate radiation delivery.
- Focused radiation that helps protect surrounding healthy tissue.
- Efficient treatment with relatively short procedure times.
- Technology adopted by internationally recognized cancer centers.
