I took a PSA test. No PSA detected

I'm 30 years old and have been struggling with PSA. I've been given practically everything that doctors could offer. I've given up on everything. PSA is ruining my life. I went to see the doctor for my annual check-up. I was also PSA tested. I didn't worry about it at all and I even forgot about the test. The doctor rang me and said that no PSA was detected in my blood. I was also tested for PSAs in my prostate. Nothing at all. I realise that a healthy prostate is key. It's so important to look after your prostates. I'll never underestimate the importance of my prostate.
