Before You Travel
Prepare for your CyberKnife Radiosurgery journey
Medical Records & Imaging
Gather your current scans and medical history to share with your treatment team in Thailand
- Collect your most recent imaging (CT, MRI, or PET scans) and biopsy results from your current doctors
- Prepare a list of all current medications and supplements
- Your treatment-planning CT and MRI scans can be arranged at your hospital in Thailand
- PET/CT scans are also available at your hospital in Thailand if needed
Medications to Review Before You Go
A few medications may need adjustment before treatment — check with your doctor at home
- Some cancer medications (such as anti-VEGF drugs like bevacizumab) need to be stopped 4-6 weeks before — your oncologist at home will advise
- High-dose vitamin supplements (Vitamin E or C above specific doses) should be paused before treatment — your Thai team will specify which ones
- Most medications including blood thinners can usually continue — confirm with your prescribing doctor at home before traveling
- Continue anti-seizure medications and all other routine prescriptions unless advised otherwise
Virtual Consultation & Treatment Planning
Connect with your Thai radiation oncologist to review your case and confirm your plan before arrival
- Schedule a video consultation to discuss your scans, diagnosis, and treatment goals with your Thai oncologist
- Share your imaging files and medical records electronically ahead of your visit
- If your tumor is in the liver, pancreas, prostate, or certain lung positions, small gold marker seeds may be placed shortly after arrival — this is a quick minor procedure done by your medical team at the hospital in Thailand
- Confirm your arrival date so treatment planning scans can be scheduled for your first days in Thailand
Travel & Logistics
Plan your trip and practical needs for a 1-2 week outpatient stay
- Book flights — direct if possible; plan for a 1-2 week stay for 1-5 outpatient treatment sessions
- Stay near your hospital (Bangkok Hospital or Bumrungrad both offer international patient services and hotel partnerships)
- No fasting required — treatment is non-invasive with no anesthesia; wear comfortable loose clothing without metal on treatment days
- Consider travel insurance that covers medical treatment abroad — see our insurance guide for options suited to your procedure
- Check visa requirements — Thailand offers 30-day tourist visa on arrival for most nationalities

Frequently Asked Questions
What makes CyberKnife different from other radiation treatments?
CyberKnife combines frameless stereotactic radiosurgery with continuous real-time tumor tracking. Its robotic arm delivers radiation from 1,200+ positions with sub-millimeter accuracy, and Synchrony technology synchronizes beam delivery with breathing motion for moving tumors.
How many treatment sessions are required?
Most patients complete treatment in 1-5 sessions over 1-2 weeks, compared to 25-40 sessions with conventional radiation. Each session takes 30-90 minutes. Treatment is outpatient—patients return home the same day.
Is anesthesia required for CyberKnife?
No anesthesia is required. Treatment is painless and non-invasive. Patients remain awake and comfortable throughout. Mild sedation is available for anxious patients or those with claustrophobia.
What are the local control rates for CyberKnife?
Published clinical data reports local tumor control rates of 85-92% for brain metastases, 90-95% for early-stage lung cancer (per RTOG 0236/0618 trials), 85-90% for spinal tumors, and 95%+ for localized prostate cancer. Response develops over weeks to months, with maximum response at 6-24 months. Individual outcomes vary based on tumor characteristics, overall health, and treatment parameters. Your radiation oncologist will discuss expected outcomes for your specific case.
What is radiation necrosis and how is it managed?
Radiation necrosis is delayed tissue injury occurring in 2-11.5% of brain tumor patients, depending on dose and volume. Risk is higher with single fraction doses >22 Gy. It's treated with steroids (dexamethasone), bevacizumab for refractory cases, and rarely surgical resection.
Who is typically evaluated for CyberKnife treatment?
Patients commonly evaluated for CyberKnife include those with brain metastases (≤4 lesions, <3cm each), spinal tumors, early-stage lung cancer, localized prostate cancer, and those who are medically inoperable or prefer non-surgical treatment. It may be particularly suitable for elderly patients and those with comorbidities. Your radiation oncologist will assess your eligibility based on your complete medical history and imaging studies.
What are the contraindications for CyberKnife?
Absolute contraindications include pregnancy (fetal radiation exposure). Relative contraindications include prior radiation to the same area (requires dose assessment), tumors >5cm, severe autoimmune connective tissue disease affecting the treatment site, and severe respiratory failure preventing 30-90 minute supine position.
How much does CyberKnife cost in Thailand vs. the US?
CyberKnife treatment in Thailand costs $10,000-$15,000 at JCI-accredited centers, compared to $30,000-$80,000 in the US—a savings of 50-80%. This includes radiation oncologist fees, physics planning, equipment, and treatment delivery.
What are fiducial markers and when are they needed?
Fiducial markers are small gold seeds (1mm x 5mm) placed near soft tissue tumors for real-time tracking. They're needed for liver, pancreas, prostate, and some lung tumors (<15mm). Placement is done 5-7 days before treatment via CT-guided, endoscopic, or bronchoscopic approach.
When can I travel after CyberKnife treatment?
Most patients can travel 2-3 days after completing treatment if no complications arise. Brain tumor patients with significant edema may wait 5-7 days. Physician clearance is recommended before departure. Plan for 1-2 weeks total stay including pre-treatment and post-treatment observation.
What follow-up is required after returning home?
First follow-up imaging (MRI or CT) at 2-3 months, then every 3-6 months for years 1-2, and every 6-12 months thereafter. Thailand treatment centers offer 24/7 telemedicine access and can coordinate with home oncologists for remote imaging review.
Can CyberKnife treat recurrent tumors after prior radiation?
Yes, CyberKnife can treat recurrent tumors in previously irradiated areas, depending on cumulative dose assessment and timing. Its precision allows re-irradiation while minimizing dose to surrounding tissues. Prior radiation records are essential for treatment planning.
CyberKnife represents the most advanced non-invasive radiation treatment available, combining robotic precision with real-time tumor tracking. Unlike conventional radiation requiring 25-40 sessions, CyberKnife completes treatment in just 1-5 outpatient sessions. The system’s sub-millimeter accuracy allows high radiation doses to tumors while sparing surrounding healthy tissue.
Thailand Advantage: Treatment costs $10,000-$15,000 in Thailand compared to $30,000-$80,000 in the US—savings of 50-80%. Bangkok Cancer Hospital Wattanosoth operates the EDGE radiosurgery platform (Varian), while Bumrungrad International Hospital offers advanced stereotactic radiosurgery capabilities. Both are JCI-accredited with dedicated international patient coordinators.
Clinical Outcomes: Local tumor control rates exceed 85% across most tumor types. Brain metastases achieve 85-92% control at 2 years, early-stage lung cancer (Stage I) achieves 90-95% local control, and spinal tumors demonstrate 85-90% control with 70-90% pain relief. Prostate cancer patients report 95%+ biochemical control for low-risk disease.
Treatment Experience: No anesthesia is required—patients remain awake and comfortable during the painless procedure. Each session takes 30-90 minutes, and patients return to their hotel the same day. Most people resume normal activities within 1-3 days. The treatment is particularly suitable for elderly patients and those with comorbidities who may not tolerate surgery.
