I'm 68 y/o, diagnosed with PCa at 67 y/o...close to your age.

My urologist did not prescribe my exercise/diet program; however, he knows all about it and has been generally encouraging.

I would be surprised if any urologist would "prescribe" an exercise/diet plan...they are usually not trained in this area and "exercise/diet plans" have the disadvantage of taking a lot of time to personalize and require dedicated effort over a long period of time (years)...not things the medical establishment or most Americans are inclined to accept, much less implement.

A quick decision to surgery, radiation and/or drugs are easier to prescribe and implement (not to mention...more profitable). Don't get me wrong, these things definitely have their place for PCa in the "Unfavorable Intermediate Risk", stage or worse.

However, it's also abundantly clear, from the scientific research, that AS is the most appropriate decision for those diagnosed with "Low Risk" PCa. The problem is more of a psychological one...some men simply stay freaked out upon being diagnosed with a condition that has the word "cancer" associated with it..even if "low risk".

I'm a retired chemical engineer who spent most of my 45 year ChE career doing scientific research. I've probably read and studied more than many urologists, regarding exercise/diet for PCa...it's an inherent weakness in the practice of Medicine 2.0...read "Outlive", by Dr. Peter Attia for a comprehensive treatise...https://peterattiamd.com/outlive/

I'm not naive enough to believe that any particular exercise/diet program will cure PCa...the research does not support that conclusion. However, there are hundreds of studies and 6 random control trials demonstrating aerobic exercise slows down the progression of PCa. A good meta study to begin with can be found here https://www.nature.com/articles/s41391-024-00801-7

At the end of the day, every man decides (or allows another to decide for him) as to what level of risk they are willing to accept.

All the best with your decision.
