 Some prostate cancers are literally watched like don't even turn into anything and you just kind of watch it Don't even take out the prostate because they're just so non-aggressive But that's not always the case prostate cancer is basically in two different categories, okay? The first thing is is it aggressive or not? And like I said some standard of care is to see is just to watch it basically the PSA prostate specific antigen Nothing else in your body makes this wouldn't it be nice if there was like a PSA prostate specific antigen But that kind of marker for all the other cancers and all the other tumor types We're getting there and we're learning about them, but at least for the prostate We've isolated something that's only from prostate tissue. That's important so the cancers that are less aggressive those are the ones that are literally watched and You just watch that PSA and if it's not doubling like the number or the count in six months or a year You know that cancer is very non-aggressive
