Hi Folks from the great smokies in tennessee. My Gasto doc after many tests said he thinks 90% chance of Bile Duct cancer. He is sending me to see DR Peter Cotton at USC. Two out patient procedures , ultrasound and ERCP. All my tests MRCP, blood work and brushing of the bile duct were negitive. He says I am 95% cureable because it was found so early. Anyone ever here of Doctor Cotton or had any work done at USC ?
