Re: scar tissue
Tetonteri66's message teaches a very important lesson that all patients AND doctors need to be reminded of from time to time. When interpreting the results of imaging studies and other diagnostic tools, a doctor's preconceived bias toward a given diagnosis can cause them to miss important clues. Once a doctor has framed a diagnosis in this fashion, it's difficult to keep from making further errors in a patient's care. Jerome Groopman explains this common problem (and several others) very clearly in his The book entitled "How Doctors Think."
