The cost of radiotherapy in Thailand typically ranges from $5,500 / ฿187,000 to $10,000 / ฿340,000. Prices can vary depending on the clinic, the oncologist’s expertise, the number of sessions, and the type of technology used (such as IMRT, IGRT, or stereotactic radiosurgery). In the United States, the average cost is $30,000 / ฿1,020,000 (per ASTRO). This means radiotherapy in Thailand is about 74% less expensive than in the U.S.
Thai hospitals usually include the initial oncologist consultation, treatment planning (CT simulation), radiation sessions, and basic follow-up care in the quoted price. In the U.S., the price often covers only the sessions, with planning, imaging, and follow-ups billed separately. Always confirm exactly what’s included with your chosen clinic.
