A focused form of radiation treatment
Brachytherapy is a type of radiation treatment in which a radiation source is placed inside or very close to the area requiring treatment. It allows radiation to be delivered locally while limiting exposure to surrounding tissues as much as possible.
For selected patients with cervical cancer, brachytherapy forms an important part of radiation treatment. It may be combined with external-beam radiotherapy and chemotherapy depending on the cancer stage and the patient's overall treatment plan.
For patients from Iran considering treatment in India, the first step is a review of the diagnosis, staging investigations and previous treatment. Brachytherapy is not appropriate in exactly the same way for every patient.
AIIMS' radiation oncology services include brachytherapy, image-guided brachytherapy and interstitial brachytherapy. Its National Cancer Institute also conducts dedicated training in gynaecological brachytherapy, including cervical-cancer treatment.
Who may be considered for this treatment?
The suitability of brachytherapy depends on the type and extent of cervical cancer and the overall treatment strategy developed by the oncology team.
The specialists may review:
- Cervical cancer diagnosis and pathology
- Stage and extent of disease
- MRI, CT or PET-CT findings where available
- Previous or planned external-beam radiotherapy
- Chemotherapy or other systemic treatment
- General health and medical fitness
- Previous pelvic surgery or radiation
- Anatomy relevant to brachytherapy planning
The radiation oncologist may also work with gynaecologic oncologists, medical oncologists, radiologists and medical physicists when developing the treatment plan.
AIIMS describes its radiation oncology department as working with medical oncology, surgical oncology, pathology, radiology, nuclear medicine and palliative care through multidisciplinary disease-site clinics.
Understanding the role of brachytherapy
External-beam radiotherapy delivers radiation from outside the body. Brachytherapy takes a different approach by positioning the radiation source close to the tumour.
For cervical cancer, an applicator is placed through the vagina and cervix into the appropriate position. The radiation plan is then calculated according to the patient's anatomy and the location of the disease.
Image guidance can help the treatment team understand the position of the tumour and nearby organs during planning. AIIMS lists image-guided brachytherapy, intracavitary brachytherapy and interstitial brachytherapy among its radiation oncology facilities.
The exact number of sessions and treatment schedule varies according to the patient's treatment protocol.
Your medical records should travel before you do
Medical treatment in India from Iran. Patients can begin the treatment-planning process by organising their medical information before travelling to India.
Useful documents may include:
- Pathology and biopsy reports
- MRI, CT or PET-CT reports
- Copies of imaging studies
- Previous radiation-treatment records
- Chemotherapy records
- Surgical reports
- Blood-test results
- Current medication list
- Previous hospital discharge summaries
If previous radiotherapy has already been administered, treatment details are particularly important because the radiation oncologist may need to consider the cumulative dose received by nearby organs.
A preliminary review can help the Indian oncology team identify additional investigations that may be required after arrival.
What happens during a brachytherapy session?
The exact procedure depends on the treatment technique. For cervical cancer, an applicator is positioned in the treatment area, and imaging may be used to support treatment planning.
The radiation oncologist and medical physics team then create a treatment plan designed around the tumour and nearby organs. The radioactive source is delivered according to the planned dose and position and is subsequently removed when the session is completed.
AIIMS' documented brachytherapy programme includes image-guided procedures and training covering patient selection, technique, ultrasound guidance, post-procedure imaging and treatment planning for cervical cancer.
Patients should receive a clear explanation of the procedure, preparation, expected number of sessions and possible side effects before treatment begins.
Planning the India journey from Iran
A structured medical-travel plan can help patients avoid unnecessary delays.
|
Stage |
What usually happens |
|
Medical review |
Existing diagnosis and treatment records are assessed |
|
Specialist planning |
Radiation oncologist reviews the case |
|
Investigation |
Additional imaging or tests may be requested |
|
Treatment decision |
Brachytherapy and other treatment components are discussed |
|
Hospital planning |
Treatment schedule, admission and estimated stay are arranged |
|
Travel |
Visa, flights and accommodation are organised |
|
Treatment in India |
Radiation planning and brachytherapy are performed if indicated |
|
Follow-up |
Recovery and future oncology follow-up are discussed before returning to Iran |
The overall pathway is therefore:
Medical records from Iran → Indian oncology review → staging and treatment assessment → radiation-treatment planning → hospital arrangements → travel to India → brachytherapy and other indicated treatment → monitoring → follow-up planning → return to Iran.
Recovery between and after treatment sessions
Recovery differs from patient to patient. Some people may experience temporary pelvic discomfort, fatigue, urinary symptoms or bowel-related symptoms following pelvic radiation treatment. The treating team should explain the expected effects and the warning signs that require medical attention.
Because cervical-cancer treatment may involve several components, recovery cannot always be attributed to brachytherapy alone. External radiation, chemotherapy and the underlying cancer can also influence how a patient feels.
Before travelling back to Iran, patients should obtain copies of their radiation-treatment summary, procedure notes, imaging, medication instructions and follow-up plan.
Questions Iranian patients should ask the radiation oncologist
Before committing to treatment in India, patients can ask:
- What role does brachytherapy play in my overall treatment?
- Is image-guided brachytherapy recommended in my case?
- How many sessions may be required?
- Will external-beam radiotherapy or chemotherapy also be needed?
- What imaging is required before treatment?
- How long should I expect to remain in India?
- What side effects should I watch for after returning to Iran?
- How will follow-up be coordinated after I return home?
These questions can help patients understand the complete treatment pathway rather than viewing brachytherapy as an isolated procedure.
What to look for when choosing an Indian cancer centre
For patients from Iran, the availability of brachytherapy should be considered alongside the hospital's wider radiation and cancer-care infrastructure.
Relevant factors include:
- Experienced radiation oncologists
- Dedicated brachytherapy facilities
- Image-guided treatment capabilities
- Medical physics and treatment-planning support
- MRI and CT imaging
- Medical and surgical oncology services
- Gynaecologic oncology expertise
- Emergency and inpatient support
- Arrangements for international-patient follow-up
AIIMS' radiation oncology service demonstrates this multidisciplinary structure and lists dedicated clinics for gynaecological, breast, head-and-neck, neuro-oncology and other cancer sites.
Medical visa planning for patients from Iran
The Government of India's official e-Visa portal currently lists the nationalities eligible for e-Visa services and provides information on e-Medical and e-Medical Attendant Visas. However, Iran does not appear in the currently displayed e-Visa eligible-nationality list on the official portal. Iranian patients should therefore not assume that they can use an e-Medical Visa.
Patients from Iran should verify the appropriate medical-visa route directly with the Government of India and the relevant Indian diplomatic mission before booking flights or finalising treatment dates. Visa requirements can change, and the hospital's treatment letter may be required as part of the appropriate visa process.
