News flash. Medicine is not perfect. A few years ago, I finished my advice to a patient by saying, I might be wrong. She sarcastically said she was going to go straight home and call her doctor son-in-law to give him the news. “A doctor said he might be wrong. Who knew?”
Reading the recent news about colonoscopies made me think of this. Why do we need scientific studies to document that therapies work? Because we can’t rely on our intuitions and preconceived notions. Every diagnostic test and treatment needs to be scrutinized objectively. Even the ones we’re sure of.
