Hello Jim... I felt the same way in the beginning also. Confusion is certainly part of things until a few doctor visits and a firm schedule of events gets put into place.
After my referral consult and I knew I had to have a partial cystectomy (after my initial TURBT), I told the doctor that I needed a little bit of time to get things at home in order. I was about 85% through a pretty major remodel and the house was still in chaos. He said as long as it was no more than six weeks, he would be comfortable with that. We settled on giving me three weeks to get things organized enough to come home to afterwards. (My surgery was 300 miles away.)
My tumor was considered fairly small for its type at 1.6 cm (2/3 inch). He estimated that it might have taken 18 months or so to grow to that size but that was just a guess on his part. There's really no way to know for sure.
I wouldn't worry too much about waiting until the 17th. Just be firm about getting to the next surgical step very soon after that. I'm sure your doctor will think likewise. Until then, keep up your normal routine, take your lovely wife out, eat well, and stay rested as best you can. Try not to get run down with worry... that won't help anyone at this point.
