well I had 2 different kinds of cancer but it is always wise to also get a 2nd oppion :) ask questions too. If you get 2 Dr.s who don't agree then get a 3rd. they are all out to help . They can only figure out what is going on by the information they get scans,labs etc. so they put it together the best they can. The bigger the puzzle the harder it is. A lot of cancers also memic each other so they do the best they can. good luck
