I have heard many times that there will always be at least one illness that is uncurable. Is this a Jewish idea? What is its source?

    This is not an answer, which is why I'm not posting it as such, but there's a story (the veracity of which I can in no way vouch for) that the Chazon Ish claimed that he could cure cancer (presumably through his genius, by discovering the cure, though I've seen some interpret it as meaning that he could divine the cure through ruach hakodesh; in any event) but he did not do so because God would simply send along another illness as bad. This story is mentioned (in one of its variants) at parsha.blogspot.com/2009/07/… for example.

I'm thinking no because in Sefer Nishmat Avraham- Orach Chaim Siman 1 it is written: "Indeed, Chazal stated: The Holy One, Blessed be He, said: There is no illness for which a complete cure is not already present.

The footnote says(I'm translating from Hebrew) Tanchumah Yitro Chet
