Engaging in physical activity is associated with a lower likelihood of cancer recurrence or metastasis in individuals with circulating tumor cells.

“so the way that cancer spread is the these um it has to shed cells from the primary tumor and they have to circulate throughout the um blood vessels and they have to get somewhere else and so if you're preventing that or reducing that you should be able to reduce um the number of metastases that's absolutely critical because that's what ultimately kills cancer patients right”

“So, the circulating tumor cells, why why is it so dangerous to have them in circulation? Well, for one, um let's say you were you already had cancer and you were treated with cancer successfully, quote unquote. Let's say you're you you know, you had chemo, radiation, maybe surgery, maybe all of the all three of them, right? And and now you're tumor free, whatever. Um so, you're in remission. But the problem is is that currently in the clinic, we're not looking we're not doing single cell analysis and looking at every single cell in 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, we, you know, cancer's gone." What happens is these single cells they do escape and if they get into circulation they'll maybe go some maybe they'll travel to another organ like the liver or something and um 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 in the even in the same the same organ whatever.”
