Hi Alyssa,
I am not, but, I have a friend that work in an oncolongy clinic. She thought that I should because she see's some patients that come there after being to a Uro and there is nothing they can do for them, she calls them train wrecks. She looked into my Uro background for me and found that he is one of the best in the area and felt that I would not be better off going to an oncolongist. I guess it depends on how much you trust your uro, for me so far so good. Perhaps others here have more experience.
