Hi, many thanks for the query!
You should do- Sr. creatinine
, Sr. Uric acid, Sr. PSA, X-ray KUB, Urine (R&M).
You haven't mentioned your age which is important.
Get Per Rectal examination
gone by your Urologist
, it is must, specifically to know about malignancy (cancer) in which case it is HARD in consistency.
If collectively it turns out to be benign (non-cancerous), i.e. BEP, then medications should be started with your doctor's opinion.
Operation may not be needed as you are asymptomatic.
Wish you a good health.
