Is it normal to have a raised PSA 3 mths after biopsy

PSA's have been known to have false negatives and false positives.

In my case PSAs and biopsies without a prior MRI or PET scans was pretty useless for PCa detection.  An early six hit biopsy via the rectum (transrectal ultrasound-guided) was clear and my PSAs never went above 3.8. Once 3+4 PCa was MRI detected a 20 hit biopsy confirmed the two MRI indicated cancers the other 18 were clear. They never know how many hits to take. A massive number may detect cancer that was never going to affect life or lifestyle but promote action that will. Too few means nothing. I bled for two weeks after both biopsies and had concern about the blood from the two cancer hits causing the PCa to spread. They say this cannot happen but the only internet article I could find on it based their conclusion on a study of a different cancer and only used survival time as a guage. Like everything about the prostate there is so much they don’t know but are not backward to push you to some action that may not be necessarily the best for you. People keep using the excuse “we are all different”. I think it is only the stage of the complaint and what we want for ourselves that matters. With prostates you can’t rely on anyone like we do for other issues. Always do your own research and ask questions here.
