Can't get PSA to zero
Diagnosis of husband's stage 4 PC in September, age 48. PSA was 348 at diagnosis. Dropped to 7 after 30 days of Lupron. On 12/5 PSA was up to 11; testosterone was 10. PSA just tested on 1/9 and it's 13; testosterone is 45. He is otherwise in good health.
Why are both going up?
What actions should we be taking? This is a very short time for lupron to stop working.
I hate to consider this, but is it a bad thing that he can still gain erections and ejaculate? Is this a sign that Lupron is not enough?
Thank you for any help you can offer.
