from personal experience, always have it removed even if the urologist suggests radiation!!!!!
Had mine removed three years ago, psa tests biannually, psa started to rise, have been on hormone therapy for two months, radiation starts today, still have four months more to go on hormone therapy.
Had mine removed 5 years ago. Was caught early due to my doctor doing both digital and PSA test, no symptoms or high PSA readings at the time. PSA readings still zero.
