New Prostate Cancer Patient. DId I make the wrong decision?

Hello everyone,
I am a 61-year-old male that was diagnosed with prostate cancer in February. My urologist is a surgeon, so I decided on surgery without consulting with any other doctor's. I just want to know if I made the right decision. I will list the details below.

PSA one year ago 9.2

PSA now 7.4

Gleason score 6

Clinical stage T1c

5 out of 12 sites show cancer at 60%, 70%, 5%, 25%, and 5%

I did not consider radiation treatment since I have ulcerative colitis and am taking the drug Velsipity. I read online that radiation while taking Velsipity could cause skin cancer.
I just need advice. My surgery is scheduled in 2&1/2 weeks from now.

Did I make a decision too quickly and should I reconsider?

Thank you all for your help!
