[|Human|] 8 Year bladder cancer survivor. Mayo Clinic patient. Last visit August 2013, last month. No cancer detected. Last PSA exam 1.0 - doctor checked prostate, no concerns, urine came back no cancer cells floating around, ETC ... doctor entered bladder, took biopsy of one very small area, and reported negative returns. A few days ago .... while going to the bathroom to defecate, I noticed blood on some seminal fluid that dripped out of the tip of my penis due to borderline constipation and apparently the force to relieve myself caused this fluid. I have ordered another PSA test for this Monday. The last PSA test was 3 months ago. Any opinions? Thank you so much.
[|AI|]  Hello and welcome to Chat Doctor, Appearance of blood at penile tip could be due to blood in urine rather than blood in semen. Since there is history of bladder cancer in the past, there could be due to re-appearance of cancerous growth in bladder. At PSA levels of 1.0 NG/ml, prostatic cancer is unlikely. You need to get urine examined for malignant cells and bladder cystoscopy to see the inner part of the bladder. If there is any growth in the bladder, a biopsy can be taken for microscopic examination. If there is presence of tumor, chemotherapy and BCG treatment needs to be given. Thanks and take care Chat Doctor.
