    A very professional visit. The doctor listened to my concerns as well as followed up on any of my previous treatments outside of the Boston area. The doctor was very good at suggestions on where we proceed from here and I felt very comfortable with the visit. It was more of a consultation that I gladly will schedule an annual follow-up to keep abreast of any developments in bladder cancer as well as this doctor's opinion of the direction I'm taking. So it was a very good visit and I'm very happy that I followed through with the one-year annual follow-up.
