And you get a score, and if that score is in the top 5 or 10%, you have an increased risk compared to the average population developing with prostate cancer.

And in the trial this came from in the UK, they brought many men in, and some of those men needed to start treatment immediately.

So it's a kind of a smarter way of looking for prostate cancer.

It's only a cheek swab.

So that's being tested in a much larger trial in the UK now called the Transformer trial, and I think that, I'm hoping, that will be the future.

So definitely everyone encourages a healthy lifestyle and not smoking and all those things and keeping healthy.

But there's no definite evidence that we can avoid prostate cancer by physical exercise.

I've never been asked that, but there's no evidence that they do.

Okay.

I think, I mean, certainly men can be bad and women are probably better and Irish men sometimes can be bad at this.

But I think a lot of this stems around going to your GP and have a conversation about your general health.

And in the context of our discussion today, talking about whether a PSA and perhaps an examination is the right thing for you.

But the key thing is go and see your GP and have those conversations.

No, not at all.

In fact, an awful lot of patients that are diagnosed by prostate screening, it's somewhere between up to a half of those men, if they're diagnosed that way, actually can be suitable for surveillance.

And we have very large numbers of men on surveillance.

They're seen every six months.

They get an MRI every two years.

And many, many of those, the majority, never need treatment.

But the good thing is that those that do need treatment, we detect it and we go and treat them.
