get attention because this study found that people who have three or four of the four symptoms I just mentioned, they had a six-fold higher likelihood of having colorectal cancer than people who had fewer.

Six-fold?

Six-fold.

Yeah, I would go get help for any of these symptoms, no more than one or two weeks if it's persisted.

And there have been some really high profile cases of celebrities who have said, the only sign I had was that fourth one, just that something changed in the pattern.

And I thought it was like my coffee or something else, but then I changed the coffee and it didn't go away.

If you're worried, if something's off, don't wait, don't brush it aside as normal.

Do not be embarrassed by it.

Just run it by your doctor.

Yeah, it's an important question.

It's a big question.

We used to think about...

cancer in general as being a function of our genetics and smoking, right?

But we've stopped smoking so much as a society.

And obviously our genetics aren't changing, but what can change with generations is something called epigenetics or changes to our genes that occur on top of the actual gene itself that can be due to influences from our environment.

So as these cases have been rising, we're arriving more and more at the conclusion that

that there has to be something in our environment that is changing.

And that environment could be the air we're breathing.

It could be chemicals we're introduced to.

It could also be the foods we're eating.
