I think you're really asking if the biopsy wound is likely to be infected in the sea.
From what I recall from nearly 3yrs ago there was a warning about infection soon after the biopsy. I think 48hrs. Assuming it was a simple biopsy, not a template which penetrates the skin.
I'd go although I would question anything that presses on the prostate like cycling, although someone else might know more about that.
Prostate Cancer added about £40 to my annual holiday insurance. I've not covered it so it costs no extra.
I had a 4 week holiday with 48hrs of flying 8 weeks after my prostatectomy with no problems at all. For such surgery 6 weeks seems to be a cautious time.
