So lifting weights can also cause blood pressure changes and changes in blood flow.

Do you think both of those types of exercise could affect that pathway or is it mostly the more higher intensity sort of aerobic exercise?

And if you do reduce the number of circulating tumor cells in your vascular system, is that associated with, is there data showing that is associated with lower cancer recurrence, lower cancer mortality, for example?

How long does cancer metastasis take?

And does that vary by tumor type?

So if someone's diagnosed with, or let's say someone has stage one, they don't even know they have stage one breast cancer, prostate cancer, colorectal cancer, what's the timeline typically like to get to the next stages?

Is there any type of tracking that can be done for tracking these types?

I mean, can you get a blood test and measure circulating tumor cells?

Is that something that a test is sensitive enough to do?

Well, there are consumer-available tests like Grail that are available, these liquid biopsy tests that are done.

What are your thoughts on someone that's healthy without a family history or perhaps with a family history of cancer doing a liquid biopsy like the Grail test versus maybe the situation that you're saying, which may be a little more applicable now?

where someone has had a cancer diagnosis, has successfully, quote-unquote, successfully undergone treatment in that the primary tumor seems to have gone away, by all means, and they go and do a grail test and perhaps maybe find something or don't find something or maybe monitor, maybe someone does it yearly, annually, you know, I don't know.

What are your thoughts on those scenarios?

On the cancer recurrence side of it, let's say someone wants to pay out of pocket and they're going to go do, I say grail because that's like the biggest, probably most studied one that's out there for consumers.

Right.

And let's say they find, oh, I have a positive test.

I've got some tumor cell DNA that was detected, and it's the same kind of cancer that I was previously diagnosed with.

What would be the next steps for someone?

Do they go to the oncologist and then somehow verify?

I mean, is there any way to verify if the test is accurate or not?
