So you're in remission.

But the problem is, is that currently in the clinic, we're not doing single cell analysis and looking at every single cell and every single organ to make sure there's not even one cancer cell left, right?

Like we're just saying, oh, the tumor, we don't see the tumor, therefore cancer's gone.

What happens is these single cells, they do escape.

And if they get into circulation, maybe they'll travel to another organ like the liver or something.

And it might take a couple of decades, three, four decades, and all of a sudden you're having symptoms and you're like, well, I have liver cancer now, right?

So cancer recurrence happens, maybe it's even in the same organ,

whatever.

The point here is that the circulating tumor cells are really, they play a role in cancer metastasis to other organs, and they play a role in cancer recurrence in people that have already had cancer and perhaps been treated successfully with that cancer.

So the shearing forces are really important here because they do kill the circulating tumor cells.

That is associated with improved

outcomes either in cancer recurrence and mortality.

And that is reflective in what this study here is showing that vigorous intensity physical activity is associated with a lower cancer mortality.

And I know that was a very long winded way of explaining it, but it is a little bit of a passion of mine.

So I think there's other mechanisms at play, but I do like the shearing forces one because it's something that people don't think about, but it is, I think, once you hear it and you think about it, you're like, oh, that makes sense.

It makes sense.

Yeah.

I mean, there's obviously cancer.

There's so many things that are involved.

And I think you're going to talk a little bit about some of the hormonal and other cellular responses, which I mean, hormonal response, like there's a lot of things going on with cancer.
