Hi Gra1
You are at an awkward age. You're life expectancy is probably just under ten years, and that is around the cut off point for aggressive treatment of PCa. The treatment for PCa is worse than the disease, so the medics have a choice, treat you now and make the next two years or so of your life a bit miserable, and then you get to live to about 90 and die of some other horrible disease, or let you carry on enjoying your life in reasonable health and accept that PCa may get you at about 87, it won't be a pleasant end but it will be reasonably quick and at least you can carry on having fun for a few years.
Your cancer is not too aggressive and probably not spread. Once you start having biopsies you are on the treadmill of endless tests and treatments. A CT scan to see how things are going and give a baseline for seeing how fast it is spreading, with a view of hopefully doing nothing and maybe starting you on HT in a few years time if things start advancing sounds a good idea, to me. Does it sound a good idea to you?
Take up some dangerous sports, that's best way of avoiding death by cancer.
