So. After meeting a couple of specialists I've found that because my cancer is relatively small and slow-growing, treatment right now isn't warranted. I'll be having an MRI and another biopsy in a few months, but both doctors were of the opinion that my case warrants only what they call "active surveillance". They didn't expect to see any changes for at least 5 years.
I do still have cancer of course, but: Whew!
Thanks for everyone's support.
