Just been re-staged after a spike in my PSA (6.11). Recent bone scan clear but MRI shows a small re-growth of about 1cm in the prostatic bed. My current UK NHS consultant has always looked at starting ADT when PSA reached 10 or doubling time less than 6 months. Current doubling time is 30 months and it has taken just over 10 years since my post radiation nadir to reach this level of PSA. Would I be wise starting some sort of ADT now or could I wait until the magic 10 or perhaps even 15, my original consultant always used that number as a guide to hormonal manipulation. Any thoughts or guys with similar experience would be appreciated. If I do go for ADT and opt to have my chest irradiated does it effect nipple sensitivity? My nipples seem to help so much with getting and keeping an erection.
