Catti,
Welcome to the forum. Sorry your worries have brought you here but glad you found us.
It could easily be BPH. His PSA history up to last year would be pretty much what you would expect. This year's bump is worrisome but there are a number of things that can elevate a single PSA reading -- sex 24 hours before blood is drawn, bicycling, nasal decongestants, a mild prostate infection, etc., etc.. But you probably already knew all that. The biopsy seems sensible and will give you more info.
Is he taking anything for his enlarged prostate? If, for instance, he were to be on Avodart (to shrink his prostate) then that would tend to lower his PSA and would make the 5.4 a bit more troubling.
