This patient support community is for discussions relating to advanced or metastatic prostate cancer, biopsy, bone scan, blood in urine or semen, benign prostatic hyperplasia (BPH), CT scan, cystoscopy, erectile dysfunction (ED), hormone therapy, incontinence, pain (abdomen, lower back or hip), PSA test, prostatitis, radiation therapy, rectal exam, recurrent cancer, screening, staging (tumor size, metastasis), transrectal ultrasound, watchful waiting, and urinary difficulty, burning, or urgency (leaking).
The effects of radiation may extend for about 3 months. Hence, any determination you perform now may not be conclusive.
Your concerns about performing the bone scan are valid. This would be important to find out if the disease is limited to the prostate or not. It is unclear from your post, if during the period right after the surgery – the PSA was undetectable or not. I am guessing that it was still detectable. In this setting, it is indeed more likely that the disease is still confined to the prostate area, though I see no harm in performing the bone scans.
As to the question of the hormones, there is no clear cut guide. It seems that giving them earlier than later is generally better. But the definition of early is not clear. It is also unclear if the treatment is able to impact on duration of survival or not, but it is clear that certain symptoms of the disease are better controlled with it.
The 3 month waiting period seems reasonable, but if symptoms seem to be worsening then a re-evaluation of the plan would be in order.
Stay positive.
Good luck to both of you
