i would have to put my 2 cents in here!! as from my understandings and research.. the T4 & T5 are farther down the chain and you like have been said before have ah greater risk of impotence also the reacurrance rate is about 88.5 % which is not very good , and that not just including the side effects!these surgeons will just about tell you anything to get in your pocket .. i can remember talking to Dr. R and he said he would never perform at the T4 level because of sever sideeffects .. know thats all he does he does not even approch the T2 level.. how funny is that! these surgeons got there heads up there ass and have no clue on what they are doing !, and there supposed to be neurologist!! give me ah break!.. i can do ah better job then they could! THANKS JIN!!
