Dr. Neil Parikh

Dr. Neil Parikh at Hartford Hospital in Connecticut noticed something about human behavior.

He says this demographic's discomfort with bodily functions is a reason many don't mention seeing blood or other changes in their stool.

We need to normalize this so it comes up at dinner table.

That, he says, would save lives by getting more people to seek screenings or diagnostic tests.
