Hi, Jim.
We're on a similar timescale and treatment path. I had RARP about six months after you. Fortunately, my last PSA test, like all those before was undetectable. However, I know that I'm still at risk of BCR.
Although the slight rise may not be linked to BCR, it does warrant further investigation. I think sometimes GPs knowledge of prostate cancer and the care and management of it is very limited. I'm pretty sure I know much more about the disease than most of mine.
I've also found that often there's a lack of communication between hospital consultants and GPs.
If I were in your position, I'd be be contacting your surgery and asking them to inform your consultant of the rise or telephoning the consultant's secretary and telling them yourself.
I may have been lucky, but my consultants secretary has been fantastic. Whenever I've had any concerns she's promptly passed the details to him and quickly informed me of his response.
Best of luck, mate.👍
