Dmadi,
Very wise choice. The urologist I went to had done at least three biopsies and found nothing. Finally, after a bout with urine retention he decided he was going to remove the prostate by surgery (for and enlarged prostate?). Remember he had three negative biopsies. When he did the biopsies the nurse asked if he was going to numb the area as other doctors did. His reply "No a lot of trouble." It all went back, as I found out later, when he and I had an argument over treatment of a family member, that I thought was water over the dam. Make long story short I too had second opinion with urologist at clinic about 120 miles from home. He did find cancer and sent me to the Cancer Institute a the clinic.
I am so glad I went for second opinion and would urge all to do the same.
