Korea is worth choosing for three specific reasons. You get seen and scanned within days, a comprehensive program includes endoscopy and CT or MRI for a price in the same range as its neighbours' plainer packages, and the price you are quoted can be checked against the centre's own published figure. Below is what each one means in practice, and how the written report fits in.
The methodology line under the comparison table names every source this page draws on and the date each was read. Individual figures carry their own notes where there is more to say. The published-price claim above (that each centre’s own figure can be read in the document it publishes): Each partner centre's programme document for KMI, Medione, Severance and Ewha (KMI: https://global.kmi.or.kr/examination/foreigner_examination; Severance: https://sev.severance.healthcare/sev/patient-carer/appointment/checkup/checkup-program.do), measured 2026-09-13. Korea’s report-turnaround figure is explained in /blog/same-day-results-what-that-actually-means/. Home-market wait-time figures are each market’s own published figure, cited on its page under /compare/.
This page judges Korea on its own. The comparison between Korea, Japan, Thailand and India is a separate page.
