Franci is right, the waiting is horrible.
I thought my investigations went pretty quick with a psa of only 4.8 I had an mri that showed two suspicious areas and a biopsy was called for.
That all happened relatively fast, but the waiting for results felt eternal. It was just over two weeks after the biopsy that I was told there was no sign of cancer in the biopsy samples and discharged. But it felt like a lifetime, especially if you let negative thoughts intrude which is so easy given the tons of information available about the condition.
My only advice would be to try not to get too ahead of yourself. Yes your psa is high but it's only an indicator. There are stories on here of guys with lower psa levels than me that came back positive for cancer and ones with higher levels than you that came back negative.
I was told to take things one test at a time, don't rush into reading things into the little information you have, or you'll scare yourself witless.
Nothing happens quickly and you just have to get used to that, let the doctors do their thing and get back to you. You won't speed the process up and it's doubtful that a few weeks will make a huge difference to your prognosis.
Worrying will not alter what is happening but it can make you ill, please try to stay positive and not look into the future before anything is clear. You may be just like me and get the all clear which is wonderful and it made me thankful I didn't waste time and energy on torturing myself about something that might never happen.
Good luck and I hope your journey is as short as mine was.
