Good Day, and thank you for being with Chat Doctor ! Simple renal cysts are benign conditions that doesn't cause any pain and it doesn't become cancer. Increase in size of renal cyst usually grows less than 1\u00a0mm per year. Ct scan and ultrasound has a greater sensitivity to detect renal cyst that is why your urologist told you he is not concerned.  I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications at
