Is is possible for a human to unknowingly get cancer and survive it by means of a superior immune system?  Or would they just not get cancer in the first place?

Yes, very much indeed! But as you mentioned, we still don't know if this happens in our body and if yes, to what extent.. 

Our immune system *does* have mechanisms of detecting tumorous cells, but the problem is we don't fully know how cancers look in their earliest stages. It is however accepted now that one of the hallmarks of cancer is its ability to *evade* this immune response against it: we don't know how many of them never do, though.
