welcome back, as others have said no need to apologise for being away for a while.
The rise in your Husband's PSA is tiny and still 25 times less than a whole point and probably 250 - 500 times less than when a clinician might want to take further action. I know any rise no matter how insignificant can cause anxiety even fear, so expressing that is important for you. There are of course other explanations for the slight increase. A different lab or machine to complete the analysis, any slight infection, riding a bike pre test and the one I would love to see every man on here be able to say, orgasmic activity in the days preceding the test.
Have a lovely Christmas down under,
best wishes as always
