Issue during biopsy

I've recently had a targeted transperineal prostate biopsy. When the first sample was taken I jumped at the noise - it was a significant jump. How typical is this and what are your thoughts on the added risks?

My tumour is relatively small, but is right up against the wall of my prostate.

If you too jumped was this discussed at a later stage with your consultant?

I was warned that the first sample was going to be taken, but not about the noise. After the first sample I kept perfectly still. I wish I'd been warned ...

I have to wait, now, for 4 weeks until I get the biopsy results. My fear is that the tumour may be easily be able to leach out of my prostate, because of the added trauma. I suspect you can see where my thoughts are taking me.

Many thanks for any advice and/or feedback.
