Great choice. You might look at ADT. The treatments are easy painless quick. One month out, too early to tell. No side effects yet.
Another problem with recommending MRI guided is lack of machines. If you haven't seen Kishan's video you might look. https://www.linkedin.com/posts/view-ray-inc_dr-kishan-on-the-mirage-trial-of-mri-guided-activity-7026267727543631872-_Vj4
Are you scheduled on a Viewray?
