Thank you for your message. I hope you and your father continue to beat the beast. I have stage 4 PCa with metastases in bones, liver, and many other places. I have been getting lupron injections for nearly 5 years. Your message helped me in two specific ways. First, I was not aware that lupron is processed by the liver. My liver is under attack, so I need to reduce the stress on it. One way might be to eliminate lupron from my diet. Second, I was delighted to learn that your father's orchiectomy was so successful. I intend to have the procedure as soon as possible, and your dad's success is very encouraging.
You may already be aware that testosterone is also produced by adrenal glands and the cancer cells. Perhaps your father will eventually need some kind of chemical treatment if his PSA rises too rapidly.
