If you feel comfortable doing so, please share what the day-by-day challenges are for someone dealing with this. As you note, much depends on how far it has spread. On the other hand I think I recall learning that prostate cancer tends to be an atypically slow-growing form of the disease. So for instance, would that possibly allow room for someone to work, say, part-time while receiving treatment?
Different folks and different countries prefer different treatments. For older men with small amounts of cancer well enclosed within the prostate, watch and wait is certainly best. Growth ius usually very slow. Some prefer treatment more quickly than others, preferring to start hormone therapy. Hormone therapy prevents any further spreading. However, there are many side effects and the patient needing to be committed to much physical therapy in the gym heavy duty 3 times a week). And dietary changes usually help.
BTW. hormone treatment is the preferred treatment in much of Europe, especially in the UK because of the high cost of surgery or radiation/chemo,
============
IF THERE IS A SERIOUS AMOUNT OF CANCER OR IT IS SPREADING
Then immediate action is warranted, along with the hormone therapy to stop the spread. Choice include surgery (usually for younger me) or some kind of radiation/chemo.
For me, almost all areas of my prostate were 85% cancerous. I immediately started hormone therapy and continued until 6 months after radiation and I had a 45-day protocol of chemo. I also immediately (even before my biopsy went on a vegetarian diet which I also maintained until 6 months after the completion of chemo. Without the diet most have considerable weight gain. I didn't do all the physical gym stuff. The tradeoff was being low energy and losing muscle mass. Some say that they didn't have the energy to do all the therapy. The opposite is the truth. It is the therapy that gives you more energy.
As an aside, I have sufficient background to be able to understand the vast amount of literature available with the help of various websites dedicated to helping those with prostate cancer. I lots of info from Johns Hopkins, and also from Mayo Clinic and Harvard sites. Also, I am in a retirement community. I got lots of info from folks with direct experience. But knowing what to do is very, very difficult. Experts and oncologists disagree. The local urologists were worse than being not useful.
===========
MAKE NO MISTAKE
For folks like me, the medical issues would have been #1 as soon as there were symptoms. I understand why folks wait. Symptoms just don't disappear on their own. I well understand natural treatments, Asian medicine and diet change. That certainly helps and will cure lots of different symptoms and will help no matter what the treatment chosen.

BOTTOM LINE
I can see some ONE person on the team calling him for occasional discussions and advice. That would help him and the team. But I would not count on his participation until at least mini-camp.
