When it comes to our health, "failure" is one of the last words we want to hear. Yet, nothing in medicine is 100%. Each and every day we're learning new breakthroughs and techniques that allow us to continue advancing in the medical field. And sometimes, those advancements mean that something that we thought worked, actually didn't. This has happened all throughout history, hasn't it? Like when doctors used to use leeches to draw out the “bad blood.” This seems ridiculous to us now - silly almost. But when medical failures hit a little closer to home - in the last five, 10, 30 years - then it doesn't seem so silly.
