Every figure is sourced and dated on its own page.
The partner centres sit in four parts of Seoul, and which one you are sent to decides where it makes sense to sleep. Verified addresses, the stations they sit on, and a handful of properties within reach of each.
Korea finds two thirds of its stomach cancers while they are still localized. The United States finds under a third. That gap is the clearest argument for screening, and it is also the reason Korea's survival figures need reading carefully.
