Biopsies and scans usually take 3 weeks to report back to you (some places may be faster). Prostate Cancer (PCa) is usually not fast moving, so this doesn't matter medically, but is obviously a worry while you wait. I took the time to find out more about it, and like John said, the toolkit is a great start.
In the Profile Bio section, it's useful to list all the test results and give dates, such as PSA tests with dates (the time between tests is important info, as well as the values), and biopsy results and bone scan results. He probably had an MRI scan before the biopsy - if you have the result from that (often gives cancer location in prostate and PIRADS value, and if any sign of cancer outside the prostate), give that too. Did he have any symptoms which lead to having the PSA test in the first place? This all helps us to help answer your questions.
You will get great support from this forum, but you are early stages in diagnosis at the moment, so there's not much more we can say until you know more, but do come back with any questions.
