If nothing else, I'd think that having a good test for early diagnosis would help future cure research, for a few reasons: - Whatever specific thing is being tested becomes a candidate for future interventions. - It could give researchers a tighter pool of candidates for longitudinal studies. - As others have mentioned: any treatments that require early intervention have a better chance of working. (Similar to cancer, I imagine.)
