<s>[INST] Yes greetings to all, about 6 months ago I went in for a regular check up, everything turned out good, the doctor sent me in for a prostate sonogram because there was a very small amount of blood in my urine, she mentioned it could be nothing serious but just to make sure. After the sonogram everything looked fine she said there was only a small 3 mm cyst and said it was up to me if I wanted to check it out but that it looked ok. Is this something I should worry about? [/INST] Hi, Thanks for writing in. A 3 mm cyst in the prostate is not usually a concern. A prostatic article cyst (PUC) is an area of focal dilatation that occurs within the prostatic article. Article cysts may contain pus or hemorrhage if infected and when that happens, it is accompanied by pain and discomfort. A follow-up scan might be done after a year. It is important to know your age and any symptoms related to the urinary system. Since your doctor had said that there is no problem, I think you should not worry much about the cyst. You might take antibiotics to treat any infection that is causing the bleeding. </s>
