One thing I'd do is get another PSA test, preferably from a different lab, to make sure the first one is valid.
How old are you?
Do you have an enlarged prostate?
This can cause higher than 'normal' readings.
Same if you've experienced an ejaculation 24-48 hours prior to the drawing of blood.
I do have BPH (enlarged prostate), and my PSA ranges between 3.8 and 7. Up one time, down the next.
I did research online about prostate biopsy prep.
Laxative the day before, Fleet enema the morning of the procedure, etc.
All to lessen the chances of infection.
A week or so before the biopsy, having heard nothing from the urologist, I called and talked to one of his nurses. I asked about prep.
"Oh the chance of infection is so low we don't put you through all that any more."
Hunh? OK...???
"I'm taking 83 mg of enteric aspirin (blood thinner) a day. Should I stop that?"
"No, that's OK."
Hunh??? again.
Well, doctor knows best.
When I was up on the examination table about to have the biopsy, the doctor said "You're not on any blood thinners, are you?"
I thought this was a fine time to ask.
"Yes, as I told your nurse, I'm taking 83 mg of aspirin daily."
"Oh, it'll probably be OK."
PROBABLY?
I should have walked out right then, but I didn't.
The biopsy itself really wasn't THAT bad. He partially deadened the area and I just felt pressure and some pin pricks. It was a 12 point biopsy.
When they finished I was led into an adjoining room, handed a box of Kleenex, and left alone to clean myself up.
There was an amazing amount of blood. Went through several tissues and finally stuffed a wad up my butt.
I was in a state of mild shock.
Sat in my car for several minutes, smoking a much needed cigarette and gathering my wits.
Finally felt able to drive the half hour home.
I peed blood for two weeks or more.
A friend who'd had the same procedure a few months before me told me he had blood in his urine for a couple of days.
If you're on any kind of blood thinner and can safely stop, quit for 2 weeks prior to biopsy.
P.S. I have a different urologist now.
Much better guy.
Good luck.
