Korean language help

I have a problem with the definition of "advanced disease" in Korean. There apparently the understanding is that this applies to a disease which was treated but despite that advanced

But this is also precisely how almost all native English speakers would understand "advanced disease." I'd assume, for instance, that a person with advanced pancreatic cancer had only a very short time to live.

disease which currently is not in a stage early enough for curative intervention

I'd call that an "incipient disease."

In English, or at least medical English, diseases that progress are often described as having "stages."

Some, especially cancer, are described as Stage 1, Stage 2, etc. There are different standard for different diseases, but Stage 4 is often considered too late for a likely cure.

Other, more general terms, are early stage, advanced stage, late stage, and end stage. Early stage might mean the disease has been diagnosed quickly enough that there is a good change of a cure. Advanced stage may mean that the disease is progressing and the chances of a cure do not look good. Late stage generally means that chances of a cure are very poor. End stage means the end appears to be inevitable--the patient is dying, or for some diseases, will die without a transplant. (Sometimes advanced & late are used to mean the same thing--a very poor chance of a cure)

Early, advanced, and late stage are often used informally, and may have no agreed upon definition.

Outside of a serious, formal medical discussion, I'd guess that "advanced stage" or "late stage" is what you are looking for.

Nutrax, that's not how I understood the OP at all. S/he seems actually to need the Korean term for incipient disease, one that has not reached an advanced stage.

advanced disease means disease which currently is not in a stage early enough for curative intervention.

I think this means "disease that has advanced beyond a curable stage"

Ah. I see your point now. My bad.
