Radiation therapy in Iran is used to treat many types of cancer by delivering carefully planned doses of high-energy radiation to tumors while limiting exposure to surrounding healthy tissues as much as possible. Depending on the cancer, radiotherapy may be used alone or combined with surgery, chemotherapy, targeted therapy, immunotherapy, or hormonal treatment.
Iran has an established radiation-oncology network offering conventional external-beam radiotherapy as well as more advanced techniques at selected centers, including:
- 3D conformal radiation therapy;
- IMRT;
- VMAT;
- IGRT;
- SBRT;
- SRS;
- and brachytherapy.
For international patients considering cancer radiotherapy in Iran, treatment planning is particularly important because radiation therapy often requires multiple sessions over several days or weeks.
On Tabeebo, patients can explore radiation oncologists and radiotherapy centers in Iran, compare available services, and review provider information before deciding where to receive treatment.
What Is Radiation Therapy?
Radiation therapy, also called radiotherapy, uses ionizing radiation to damage the DNA of cancer cells and reduce their ability to continue dividing.
The treatment is planned to concentrate radiation in the tumor while protecting nearby organs and normal tissue.
Radiation does not destroy every cancer cell immediately. Its effect develops over time, which is one reason many treatments are divided into multiple sessions known as fractions.
The number of fractions depends on:
- the type of cancer;
- tumor location;
- treatment goal;
- total radiation dose;
- technology used;
- previous treatment;
- and the patient's overall condition.
Which Cancers Can Be Treated With Radiation Therapy?
Radiotherapy is used in the management of many cancers, including selected cases of:
- breast cancer;
- prostate cancer;
- lung cancer;
- brain tumors;
- head and neck cancers;
- rectal cancer;
- cervical cancer;
- bladder cancer;
- esophageal cancer;
- stomach cancer;
- lymphoma;
- sarcoma;
- bone metastases;
- brain metastases;
- and other solid tumors.
Whether radiation is appropriate depends on the individual cancer and stage.
Two people with the same organ cancer may require very different radiotherapy plans.
Radiation Therapy Before Surgery
Radiotherapy given before surgery is called neoadjuvant radiation therapy.
The purpose may be to:
- shrink a tumor;
- improve the possibility of complete removal;
- or reduce the risk of cancer cells remaining around the surgical area.
For some cancers, radiation is combined with chemotherapy before surgery.
Rectal cancer is one example where preoperative treatment may be part of the management plan in selected patients.
Radiation Therapy After Surgery
Radiotherapy may also be given after surgery as adjuvant treatment.
The aim is usually to destroy microscopic cancer cells that could remain after the visible tumor has been removed.
Examples can include selected patients with:
- breast cancer;
- head and neck cancers;
- brain tumors;
- prostate cancer;
- and other cancers.
The decision depends heavily on the pathology report, surgical margins, lymph-node involvement and other risk factors.
Radiation Therapy for Advanced Cancer
Radiotherapy is not used only with curative intent.
It can also be used as palliative radiotherapy to relieve symptoms caused by advanced cancer.
This may help with problems such as:
- painful bone metastases;
- bleeding;
- pressure on nerves;
- brain metastases;
- spinal-cord compression;
- or symptoms caused by a tumor pressing on nearby structures.
Palliative courses are often shorter than curative radiotherapy courses.
External Beam Radiation Therapy
External Beam Radiation Therapy – EBRT is the most common form of radiotherapy.
A machine called a linear accelerator or LINAC directs radiation toward the tumor from outside the body.
Before treatment begins, patients usually undergo a planning process that may include:
- CT simulation;
- immobilization devices;
- contouring of the tumor and organs at risk;
- dose calculation;
- and computerized treatment planning.
The actual treatment session is usually much shorter than the planning process.
3D Conformal Radiation Therapy
3D-CRT uses imaging and computerized planning to shape the radiation beams around the three-dimensional form of the tumor.
It remains useful for many cancers and can provide appropriate treatment when more complex modulation is not necessary.
The newest technology is not automatically required for every patient.
The technique should match the tumor and clinical goal.
IMRT in Iran
Intensity-Modulated Radiation Therapy – IMRT allows different parts of the radiation beam to deliver different intensities.
This can help shape the dose around complex tumors while reducing exposure to selected healthy structures.
IMRT may be particularly useful when tumors are close to sensitive organs, including some cancers of the:
- head and neck;
- prostate;
- brain;
- pelvis;
- and other anatomically complex areas.
IMRT usually requires detailed planning and quality assurance before the first treatment.
VMAT Radiation Therapy
Volumetric Modulated Arc Therapy – VMAT is a form of intensity-modulated radiotherapy in which the treatment machine rotates around the patient while continuously adjusting the radiation beam.
VMAT can deliver highly conformal treatment efficiently and may reduce the time required for an individual session compared with some conventional IMRT plans.
Whether VMAT or another technique is preferable depends on the tumor and planning objectives.
IGRT
Image-Guided Radiation Therapy – IGRT uses imaging immediately before or during treatment to verify the position of the tumor and patient.
This is important because internal organs can move and patient positioning can vary slightly between sessions.
IGRT may be particularly useful for treatments requiring high positional accuracy.
SBRT in Iran
Stereotactic Body Radiation Therapy – SBRT delivers a high radiation dose very precisely over a relatively small number of sessions.
A typical course may involve approximately 3 to 5 treatments, although protocols vary.
SBRT can be used in selected cases such as:
- early-stage lung cancer;
- limited metastatic disease;
- liver lesions;
- spinal tumors;
- prostate cancer in selected protocols;
- and other well-defined targets.
Because each fraction delivers a high dose, accurate imaging, immobilization and treatment planning are essential.
SRS for Brain Lesions
Stereotactic Radiosurgery – SRS is a highly focused form of radiation used mainly for abnormalities in the brain and sometimes nearby structures.
Despite the word “surgery,” there is usually no surgical incision.
SRS may be used for selected:
- brain metastases;
- benign brain tumors;
- arteriovenous malformations;
- and other intracranial conditions.
Treatment can be delivered in a single session or a few highly focused fractions depending on the lesion.
Brachytherapy in Iran
Brachytherapy places a radioactive source inside or very close to the treatment area.
Because the source is positioned close to the tumor, a high dose can be delivered locally while radiation falls off rapidly outside the target.
Brachytherapy is used in selected cancers such as:
- cervical cancer;
- prostate cancer;
- endometrial cancer;
- and some other tumors.
It may be performed as HDR – High-Dose-Rate brachytherapy or, in selected conditions, with lower-dose-rate techniques.
Not all radiotherapy centers provide brachytherapy, so patients should confirm availability before traveling.
Does Radiation Therapy Make the Patient Radioactive?
With standard external-beam radiotherapy, the patient does not remain radioactive after the treatment session.
Patients can generally be around family members normally after leaving the treatment room.
Some types of brachytherapy or radionuclide therapy are different and may require temporary precautions.
The treating team should explain any necessary restrictions.
Radiation Therapy Planning
Planning is one of the most important stages of radiotherapy.
Patients may undergo a CT simulation in the exact position that will later be used for treatment.
Special immobilization devices may be required, such as:
- thermoplastic masks for head and neck treatment;
- body molds;
- vacuum cushions;
- or other positioning systems.
The radiation oncologist identifies:
- the tumor;
- areas at risk of microscopic disease;
- and nearby normal organs that should receive the lowest possible dose.
Medical physicists and dosimetrists then help create and verify the treatment plan.
How Many Radiation Sessions Are Needed?
There is no standard number for all cancers.
Examples can range from:
- a single treatment for some palliative indications;
- 3–5 fractions for selected SBRT treatments;
- around 5–15 sessions for some shorter protocols;
- to 20–35 or more sessions for many conventional curative treatments.
Some prostate protocols may involve considerably different schedules depending on the technique.
Patients should therefore be cautious with price advertisements that quote “radiotherapy” without stating the number of fractions and technique.
Does Radiation Therapy Hurt?
The radiation beam itself cannot normally be felt during an external-beam treatment session.
The patient lies on the treatment table while the machine moves around the treatment area.
Side effects develop because normal tissues near the treatment site receive some radiation, not because the patient feels the radiation entering the body.
Side Effects of Radiation Therapy
Side effects depend strongly on the part of the body treated.
General effects may include:
- fatigue;
- skin changes in the treatment area;
- appetite changes;
- and temporary inflammation of tissues exposed to radiation.
More specific effects can include:
Head and neck radiotherapy
- dry mouth;
- difficulty swallowing;
- mouth soreness;
- taste changes.
Chest radiotherapy
- swallowing discomfort;
- fatigue;
- skin irritation;
- and, less commonly, lung inflammation.
Pelvic radiotherapy
- bowel changes;
- urinary symptoms;
- fatigue;
- and possible effects on sexual or reproductive function.
Brain radiotherapy
- fatigue;
- hair loss in the treated area;
- headache or swelling in selected patients;
- and other effects depending on the brain region treated.
The radiation oncologist should discuss expected effects before treatment begins.
Are Radiation Side Effects Permanent?
Many side effects improve after treatment, but some can appear months or years later.
Late effects depend on:
- the treated organ;
- total radiation dose;
- dose per fraction;
- age;
- previous chemotherapy or surgery;
- and individual sensitivity.
Modern planning techniques aim to reduce unnecessary radiation to healthy tissues partly to reduce these long-term risks.
Radiation Therapy and Chemotherapy
Chemotherapy and radiation are sometimes used together.
This is called chemoradiation.
Chemotherapy can make cancer cells more sensitive to radiation in certain cancers.
However, combining the treatments may also increase side effects.
Chemoradiation is used for selected cases of:
- head and neck cancer;
- cervical cancer;
- rectal cancer;
- lung cancer;
- esophageal cancer;
- and other malignancies.
It is not necessary for every patient receiving radiotherapy.
Radiation Therapy vs Chemotherapy
Radiation therapy is primarily a local treatment, meaning it targets a defined area of the body.
Chemotherapy usually circulates throughout the body and is therefore considered a systemic treatment.
Neither method is universally better.
Cancer treatment may involve:
- radiation alone;
- chemotherapy alone;
- both treatments;
- surgery;
- immunotherapy;
- targeted therapy;
- or combinations of several approaches.
Radiation Therapy Facilities in Iran
Iran has developed a substantial radiotherapy network.
Recent published analysis based on international radiation-therapy infrastructure data identified approximately 81 radiation therapy centers in Iran, with more than 120 megavoltage treatment units and a smaller number of brachytherapy units.
Facilities are not evenly distributed across the country, and Tehran has a particularly high concentration of radiation-treatment equipment.
International patients should therefore confirm whether a particular center provides the exact technology recommended for their cancer.
Radiation Therapy Cost in Iran
Cost review: August 2026
The cost of radiation therapy in Iran varies enormously depending on:
- cancer type;
- treatment technique;
- number of fractions;
- treatment planning complexity;
- hospital or cancer center;
- imaging requirements;
- and whether the quotation is a local tariff or an international-patient package.
A single national “radiotherapy price” is therefore not meaningful.
Local Private-Pay Radiotherapy Costs
Recent Iranian private-sector estimates provide approximate local self-pay ranges such as:
IMRT
Approximately:
200–450 million toman
for a multi-session course.
At an exchange rate of roughly 206,000 toman per US dollar, this is approximately:
0–,185
VMAT
Approximately:
60–110 million toman
≈ 0–5
SBRT
Approximately:
150–250 million toman
≈ 0–
HDR Brachytherapy
Approximately:
70–120 million toman
≈ 0–5
These are approximate local private-pay figures rather than guaranteed prices and can vary significantly by center and treatment protocol.
Radiation Therapy Costs for International Patients in Iran
International-patient quotations can be substantially higher than domestic medical tariffs because they may include:
- treatment planning;
- specialist consultations;
- repeated hospital visits;
- international-patient coordination;
- translation;
- imaging;
- transport;
- and other services.
A current Tehran cancer-center listing provides examples such as:
- brain metastasis, approximately 10 sessions: about ,350;
- lymphoma, approximately 15–25 sessions: about ,000–,800;
- prostate radiotherapy: approximately ,200–,400;
- breast radiotherapy: approximately ,800–,300;
- lung radiotherapy: approximately ,800–,000;
- head and neck radiotherapy: approximately ,300–,000.
These figures should be treated as examples from one current international-patient program, not national radiotherapy tariffs.
For Tabeebo users, the safest approach is to request a personalized quotation after the center reviews the pathology and imaging.
Why Are International Radiotherapy Quotes Higher?
Radiotherapy is different from a one-day surgical procedure.
An international patient may need to remain near the treatment center for several weeks.
The package may therefore include or coordinate:
- repeated treatment visits;
- accommodation;
- interpreter services;
- imaging;
- medical consultation;
- chemotherapy when relevant;
- transportation;
- and support throughout the course.
Patients should compare these services before concluding that one center is dramatically more expensive than another.
What Should a Radiation Therapy Quote Include?
Before traveling, ask whether the price includes:
- radiation oncologist consultation;
- pathology review;
- CT simulation;
- treatment planning;
- dosimetry;
- immobilization equipment;
- all prescribed radiation fractions;
- IGRT imaging;
- specialist follow-up;
- and management of expected treatment-related side effects.
If chemotherapy is given concurrently, confirm whether it is included or billed separately.
Also ask whether repeat imaging or additional treatment fractions would create extra charges.
Information to Send Before Traveling to Iran
International patients should ideally provide:
- pathology report;
- pathology slides or blocks if review is required;
- CT, MRI or PET/CT images;
- surgical reports;
- previous radiation records;
- chemotherapy history;
- medication list;
- and a summary of current symptoms.
Patients who have received radiotherapy previously should provide the previous radiation dose and treatment plan whenever possible, because healthy tissues have limits on the total dose they can safely receive.
How Long Should International Patients Stay in Iran?
This depends primarily on the treatment schedule.
An SBRT course may be completed within days, whereas conventional radiotherapy can require:
several weeks of weekday treatments.
For example, a 30-fraction course may involve approximately six weeks of treatment.
Patients should not book travel based solely on the number of fractions because planning, simulation and medical review can add additional days.
Can Radiation Therapy Be Interrupted for Travel?
Unplanned interruptions may affect the effectiveness of some radiotherapy courses.
Patients should discuss religious holidays, travel requirements and other schedule concerns with the radiation oncologist before starting treatment.
Once a multi-week curative course begins, completing treatment according to the planned schedule is generally important.
How to Choose a Radiation Therapy Center in Iran
Instead of searching only for the “best radiotherapy center in Iran,” compare specific capabilities such as:
- radiation-oncology specialists;
- treatment technology available;
- CT simulation;
- IMRT and VMAT capability;
- image guidance;
- SBRT or SRS when required;
- brachytherapy when indicated;
- medical physics and quality-assurance support;
- experience with the specific cancer type;
- multidisciplinary oncology services;
- and follow-up arrangements.
A center with SBRT equipment is not automatically better for a patient who needs conventional breast radiotherapy, and a center without brachytherapy may not be appropriate for a cervical-cancer treatment plan requiring it.
Questions to Ask a Radiation Oncologist
Useful questions include:
- What is the goal of radiation in my case?
- Is it curative, adjuvant or palliative?
- Which technique do you recommend?
- Why do I need IMRT, VMAT, SBRT or another approach?
- How many fractions will I receive?
- What is the total radiation dose?
- Which healthy organs are at risk?
- What side effects should I expect?
- Will I need chemotherapy at the same time?
- How long should I remain in Iran?
- What happens if a treatment session is missed?
- What follow-up will be needed after I return home?
- And what exactly is included in the quoted cost?
Compare Radiation Therapy Centers in Iran
On this page, patients can explore radiation oncologists and centers providing radiation therapy in Iran and compare available information about their services, technologies and locations.
Radiotherapy is highly individualized. The correct treatment is determined by the cancer type, stage, treatment goal and anatomy—not simply by selecting the newest machine.
For international patients, the treatment schedule and total package are particularly important because radiotherapy can require repeated visits over several weeks.
Tabeebo helps patients discover and compare healthcare providers and does not replace individual cancer assessment, multidisciplinary treatment planning or recommendations from a qualified radiation oncologist.
