When I had second opinion at Duke they did there own biopsy and test. Although Baptsit Hospital (a CCC) provided me with all of the tests results, CD's etc. Duke looked at them but wanted tyhier own staff to look at. I was all for it, the more experts that looks at your tests/treatments the better, I think. I also like teaching hospitals for that reason...because I was on a special test protocol sometimes I would have 2 different ENT, Rad Drs look me over on two seperate days plus a few residents. A couple of times someone would see/find an issues and bring up with the others. In my simple way of thinking I was hoping that 6 Drs reviewing my treatments would be less inclined to miss something.
