There's a lot to this, if you look hard enough you'll find something wrong. But that something wrong probably would have never progressed into something that kills you - however the interventions you then undergo are not without risk. Like if you have the slow-growing prostate cancer, you'll die of something else. But if you operate you're taking risks of surgery and lifetime incontinence, and might spread it elsewhere in the body. However, I still think early detection is an important first step to finding better interventions. Once you know it's there you can start to come up with less risky/invasive treatments. The odds of dealing with it at an early stage are so much better and the scope of the intervention required so much smaller.
