How so they determine false negatives? Are there other less broad and more expensive test?

That said, isn't it also possible at Stage 1 for the body to cure itself? That is, __in theory__ is it possible Stage 1 defecation is too early? That med intervention could be premature?

You test for false negative rate by testing known cancer patients. A patient with cancer, but a clean test, is a false negative.

I think you meant detection—and not defecation—right?

Yeah. Oops. Autocorrect FTL
