Re: How much does a endoscopy cost?
You're not just looking for cancer, especially the 1st time. You're looking for various causes. The possibility of gastritis, too much bile on an allegedly empty stomach, and the biggie - ulcers. I'm sure there are other things to look for.
Of course, in theory most of these things would be the 1st time. But then, the average recommendation of every 2 years for an endoscope shouldn't be too high a price to pay.
