Now from Times Square, here's what you need to know.

The new study is looking at the efficacy of the new blood test for colorectal cancer screening.

What do we need to know?

So we've talked about colonoscopies on this show.

I've joined you to your first colonoscopy.

I think it's so important to talk about this, but it's more important to know about the facts

and the data around different types of colon tests.

And so this new study helps us to understand

And here's what you need to know.

In this study, they found that colonoscopies and stool testing

were up to 70% effective in detecting cancer and also being able to prevent death.

And when you compare that to blood tests, they found that blood tests were 42% successful

at detecting new cancers and about 56% successful at preventing death or decreasing or

associated to a decrease in death.

Now what does this mean?

Obviously, every different person's options are different depending on what their access is, but there's still a gold. Every different but at the bottom line like I always say screening is better than no screening at all.

You know I think some people don't have the access, the time of the opportunity

and in that case if you don't have access to an colonoscopy I think a blood test is a very reasonable option and I think it increases access to so many who might not be able to see a gastrointestinal
