I understand where your husband is coming from. Like your husband, I also was diagnosed with stage 3 PCa. Aside from rising PSA I had zero symptoms that there was a problem. I was in near athletic shape for being 68 yo and looked much younger. By the time I was diagnosed I was close to needing a urinary diversion (ostomy) and a natural cure was out of the question. I couldn’t believe it, was heartbroken, in denial and depressed. I was of the belief that after treatment, life would not be worth living. I sought a second opinion which convinced me of the direction I needed to take. My health team has put the odds of permanent remission at 80% and in the absence of a full remission they believe that the disease can be managed well enough that I should live into my 80s.
I had my prostate and some lymph nodes removed mid January, started ADT about a month ago and will start six weeks of radiation in June. So far, my fear that life would not be worth living has proved to be unjustified. The things that are different are certainly manageable. I look forward to enjoying something each day and refuse to let cancer find me as a person. If your husband ever wants to talk to me and asked me any questions, I invite you to send me a private message to set things up. All the best to both of you.
