How Much Does 6 Weeks of Radiation Therapy Cost in 2026?

Costs for a six-week course of radiation therapy vary depending on technique, number of sessions, and cancer type, so the final figure can only be confirmed through a hospital estimate — this site does not list a set amount. That said, we can confirm the remote review (pre-arrival review) fee of KRW 1,000,000 (about US$730) and how the estimate is structured.

Key Takeaways

• Radiation therapy costs depend on technique (IMRT, SBRT, etc.), number of sessions, and cancer type, so the final amount is set through the hospital's estimate — this note does not state a fixed figure.
• The remote review (pre-arrival review) fee is KRW 1,000,000 (about US$730). If you proceed to contract treatment after the remote review, this amount is deducted from your treatment bill.
• Actual irradiation sessions are given five days a week, on weekdays, with each visit taking about 15–30 minutes including setup. Curative-intent treatment is typically delivered in divided doses over several weeks.
• Treatment planning and verification of the radiation dose usually take about a week before treatment begins, so for a six-week course of irradiation, you should factor in this planning period when estimating your total stay.
• The estimate breaks down costs by category — exams, treatment, interpretation, lodging, and transportation — as separate line items.

Why isn't a fixed radiation therapy cost given in advance?

Even when described as '6 weeks,' radiation therapy can differ substantially depending on the treatment site, technique (intensity-modulated radiation therapy — IMRT, stereotactic body radiation therapy — SBRT, etc.), number of sessions, and whether chemotherapy is combined. Curative-intent treatment is delivered in divided doses over multiple weeks; SBRT is typically completed in far fewer sessions; and treatment aimed at symptom relief often requires even fewer sessions still. So even under the same '6-week' label, actual radiation dose and equipment time can vary considerably. For this reason, cost is confirmed only after the written opinion and hospital estimate stage, once cancer type, stage, and treatment site have been verified.

What is the sequence of steps before treatment begins?

1. Step 1: Simulation. A CT scan is taken in the same position used during treatment, an immobilization device (a mask, for head and neck sites) is made to reproduce the exact position at every session, and position markers are placed on the skin.
2. Step 2: Dose planning. The radiation oncology and medical physics teams design and verify the dose plan, which usually takes about a week.
3. Step 3: Actual irradiation. Sessions occur five days a week, on weekdays, with each visit taking about 15–30 minutes including setup — though the actual radiation delivery itself lasts only a few minutes.
4. Step 4: Follow-up monitoring. During treatment, weekly check-ups assess skin condition and overall status; after treatment ends, long-term follow-up continues to monitor for late-onset side effects.

What items are broken down in the estimate?

The estimate separates costs into line items for exams, treatment, interpretation, lodging, and transportation. The KRW 1,000,000 (about US$730) remote review fee is deducted from your treatment bill once you sign a treatment contract. Length of stay depends on the planning stage (usually about a week) and the number of irradiation sessions, so your exact stay duration and cost will be confirmed at the written-opinion stage, after your cancer type and stage have been reviewed.

FAQ — Is the remote review fee included in the treatment cost?

The remote review (pre-arrival review) fee is KRW 1,000,000 (about US$730), set separately from the cost of the radiation therapy itself as a fee for the review process. However, if you contract for treatment after the remote review, this KRW 1,000,000 is deducted from your actual treatment bill, so there is no duplicate charge in the end.

FAQ — Since I have to go to the hospital every day, will lodging costs be high?

Radiation therapy is delivered on an outpatient basis, five days a week on weekdays, with each visit taking about 15–30 minutes including setup. Because of this schedule, choosing lodging within walking distance of the hospital significantly reduces the burden of transportation, and the estimate lists lodging and transportation costs as separate items apart from the treatment fee.
