Yes 0.2 is the usual figure or 3 consecutive rises above 0.1.
My husband is in a similar situation but his is rising a bit quicker. I get him in for tests every 6 weeks at the moment and it’s gone from 0.029 to 0.044 to 0.115
We had an appointment with local urology consultant and they’re still wait and see! Going to London tomorrow though for appointment with surgeon to see what he suggests.
Hopefully yours will just steady and not continue to rise anymore but just keep a close eye on it 👍
