High precision in a limited number of sessions
Stereotactic treatment delivers a concentrated dose with steep fall-off around a carefully defined target. SRS generally refers to intracranial treatment; SBRT or SABR refers to extracranial treatment. “Radiosurgery” uses radiation, not an incision. Equipment brand names do not define the clinical indication.

When focus is an advantage
Examples include selected early lung cancers when surgery is unsuitable, brain metastases and carefully chosen limited metastatic or progressing sites. Size, number, location, symptoms and the behavior of disease elsewhere all matter. A large lesion pressing on the brain may need surgery; a tumor beside a sensitive airway or bowel may need a more fractionated approach.
Few metastases do not automatically mean a local-only plan
The team should consider the pace of disease, whether all important sites can be treated and what systemic treatment is doing. Treating a few growing lesions while other disease is controlled is a different question from treating a newly diagnosed early lung cancer. The scan count alone cannot determine whether SBRT is worthwhile.
Global treatment frontiers
The frontier includes shorter treatment schedules for carefully selected tumors, not simply delivering a higher dose. A 2026 population-based report evaluated single-fraction SABR for early-stage NSCLC, adding practice-based evidence to earlier randomized Phase II work. Convenience matters, but tumor position and normal-tissue limits determine whether a short schedule is appropriate.
Long-term experience, including a five-year Shanghai lung-cancer cohort, helps assess local control and late effects. Observational follow-up and randomized comparisons answer different questions; neither supports applying a single schedule to central tumors, previously irradiated areas and small peripheral lesions alike.
Motion and previous dose
Lung and liver tumors move with breathing, so motion assessment and management are essential. Prior radiation changes the safe dose. The team should explain immobilization, image guidance, normal-tissue constraints and whether systemic therapy continues or pauses. Fewer visits do not mean the planning is simpler.
| Factor | Why it matters |
|---|---|
| Nearby airway, bowel or spinal cord | Sensitive structures may limit a single large dose. |
| Tumor size and motion | Coverage and safe margins become harder as size or movement increases. |
| Previous radiation | The new plan must account for tissue already exposed. |
Fewer treatment visits still require careful preparation
Simulation, immobilization and image review happen before the first treatment. Lung or liver targets may need breathing assessment; brain treatment needs high-quality target imaging. Ask about preparation visits as well as beam sessions when planning travel, and whether other anticancer drugs should be paused.

Location-specific late effects
Potential effects include radiation pneumonitis, chest-wall pain, fracture, edema or radiation necrosis, depending on the field. Follow-up imaging can be difficult to interpret because treatment-related changes may resemble recurrence. New symptoms and serial imaging should be assessed together.
An abnormal follow-up scan is not a diagnosis by itself
Inflammation and scarring can alter scans after stereotactic treatment. The radiologist needs the treatment date and field, and the team may compare serial scans or obtain further assessment. Report worsening breathlessness, new neurologic symptoms or escalating pain promptly rather than waiting for an image to settle.
Estimated total treatment cost
The estimated total cost of a stereotactic radiotherapy course is US$11,000–30,000, depending on whether treatment uses SRS or SBRT and the areas being treated.
| Treatment approach | Estimated total treatment cost |
|---|---|
| Stereotactic radiosurgery (SRS) | US$11,000–24,000 |
| Stereotactic body radiotherapy (SBRT) | US$14,000–30,000 |
What’s included
The total covers specialist assessment and necessary tests, simulation and treatment planning, plan verification, radiation delivery, nursing and monitoring, necessary hospitalization, routine supportive care and early follow-up. Travel and accommodation are not included.
Your treatment plan
The number, size and location of lesions, treatment sessions and any previous radiotherapy affect the final cost. Separate treatment plans or additional anticancer therapies are assessed individually. Contact us to discuss the cost of your treatment plan.
