Thank you very much, your answers have given me some peace of mind.
Hi,
Discuss the preparations needed for the biopsy with the doctor or a nurse. You are correct that biopsies generally need an enema. Some urologists use an anesthesia gel this may be part of the suppository. It is known however that an injectable anesthetic is better. This new approach has been slow to change practice of urologists, so try to explore your options for this to make your experience better.
You are correct that the there is a tendency to overdo things. The danger is really for men who have no symptoms at all - they are the most at risk for overdiagnosis and overtreatment. For your case however - since you wrote previously about prostatitis and a nodule - you belong to a different population, hence you stand to gain something from the biopsy.
