Should I have an Aquablation?

I'm 67 years old and was diagnosed with Prostate Cancer this past fall. A routine PSA test showed that my PSA jumped from 2.1 up to 5.7. So my doctor sent me for an MRI which showed I had a small lesion (2mm) that the Radiologist suspected was cancer and I then had a biopsy which proved it. I have a very slow growing cancer and doctors just want to watch it right now. The MRI also showed that my prostate is enlarged but nothing crazy at 79.5 cc. However the MRI also showed that my prostate is growing up into my bladder 26.4 mm. They called it an Intravesical Prostatic Protrusion and the doctors were concerned about it and recommend that I have an Aquablation to remove the protrusion and to reduce the overall size of the prostate. I thought about having my prostate removed but there are too many adverse side effects doing that. The doctors tell me with such a large protrusion that I'm prone to bladder infections and other problems. I'm not sure what I should do, the aquablation seems so ......
