Petal,
Yes, stage is important (it indicates if any tumor can be felt etc) and that information is usually included.
Just a matter of asking what the stage is.
Although bone problems are unusual with PSA under 20: some doctors still order a bone scan if they're considering options, just to be sure. eg: they might not want to undertake surgery to remove a prostate if the PC has already escaped to bones.
Gleason score of 3 + 4 is intermediate , but there is a high volume, so your doctor could suggest agressive treatment.
Trust all goes well,
