Cancer diagnosis has been met with an outpouring of support from Catholics and many others around the world.

He has had no carcinoma, the most common form of lung cancer discovered following the removal of a lower lobe on the pope's right lung.

The Vatican says Pope Leo will take about a week to recover and that plans to visit South America next month are still happening.

Joining us to talk about the new czar, Dr Calvin Long, a medical volunteer for the American Lung Association and surgeon with the northwestern medicine canning Thoracic Institute.

And father Paddy Gallagher, assistant professor of sociology at Loyola University, Chicago.

Thank you both for being here.

We appreciate it so far you'll get the last time we spoke was after the fire, happier occasion of Pope Leo's What was your reaction to the news of his illness?

>> You know, I found myself like a lot of the people around me here at Loyola University, a little stunned to know why this was something that was unexpected for all kinds of reasons.

You know, Pope Leo, as pope's goes relatively young, just turning 71 years old.

He's also pretty athletic guys been known to be playing tennis and swimming over the summer time on his days off that he's been taking and he takes good care of himself.

Like you've been working with the physical trainer up to 3 times a week when he was serving as a bishop before his election as the to the papacy.

So this was something that struck us really myself really as a as a shock.

I have learned in recent days that he does have a little bit of a history of cancer in his family.

So, of course, this may contribute to it.

But I really found myself and some of the people around me surprised, stunned a little wounded, you know, scared maybe even by the news that Pope Leo has has a lung cancer.

>> Understandably so.

You know it Dr Long.

The Vatican has not disclosed what stage the pope's cancers and but he did say the nodule was detected very early.

It's well localized.

How significant is early detection cases like this we cannot emphasize the importance of early detection.

Oftentimes when people are wrong on don't they just don't have symptoms.

They don't have a cough or shortness of breath people think they would have.

>> And like the father said, you sometimes we see people are very healthy and they've also never smoke.

So they don't really have traditional risk factors for lung cancer.

And we're going to find these things early is to screen imaging.

>> And we mentioned that it's, you know, the most common form of lung cancer.

What exactly is at no It is a type of in technical terms cancer of glands.

I can actually happen in different parts of the body.

In your intestines, in your stomach, you're pressed, but in the it's the most common type.

As you mentioned, and it can take on many forms that can happen in people who have smoke, but also people who haven't smoked can be something folks might not expect necessarily father killed or what his medical care look like inside the Vatican.

>> You know, pope's for many years, not surprisingly, have received a really excellent medical care.

And over the last number of years have often been treated at the Gum Ellie Hospital in Rome, but excellent facility.

There's often a personal physician that will come see the Pope, Pope Leo himself was treated as a people suite.

In fact, on the 10th floor of the Gemelli Hospital that's actually under renovation right now.

So the pope was not able to stay there, but he has a little chapel.

There were, in fact, the good news that we were hurt we have heard is that he's recovering well and was able to can celebrate Mass in chapel before returning to his own apartment.

So there is good health care that he's received over a number of time.

And as the good doctor said, we we can see evidence of that by the fact that this was detected from some of the early screenings that he was receiving.

>> Well, an early screening.

Also, the Pope underwent robotic surgery, you know, Dr Long.

We actually have a video.

Have performing some of that?

How widespread is the use of robotics in surgery right now?

Yeah, probably is very widespread in the United States different countries.

It's taking in various degrees.

Some of the Asian countries have a lot of robots and European But it really depends on whether the government or the institution wants to find robotic surgery.

And what's the advantage there?

surgery just allow surgeons to do minimally invasive keyhole surgery in a much more advanced away.

We used do it with instruments only move up and down side to side.

But now when we put these instruments into the chest, in this case, we can actually move fold 360 degrees like restate like we're actually just putting our hands in the patient without having to make big decisions to do that.

You know, Father guilty.

You mentioned the very welcome news that, as you said, you know, the pope is, you know, able to participate mask that he's, you know, seems to be recovering pretty, you know, pretty well.

You know, if he were feeling too ill or perhaps too fatigued to perform his usual duties who might step in for him.

>> So we have a number of officials who can help the governing of a enormous institution like the Roman Catholic Church.

The first person who would be stepping in as the secretary of state.

And so that would that that process would be very smooth and would run in very normal fashion.

But one instance, actually that hat that is maybe a little bit interesting and does help us understand how seriously the doctors were taking this diagnosis is that Pope Leo had a very full packed schedule up until right before he decided to have the surgery.

He did.

Let everyone know we didn't keep the secret that his audience on Sunday's regular people audience on Sunday he announced in fact to the gathered crowds that will be having this procedure.

right before that, he had had a gathering.

In fact, the men are still there of all of the presidents of the conferences of bishops from around the world.

So, for example, the presidents of the president of the United States Conference of kept at a conference of Catholic bishops is currently in Rome, as are all of the others and their meeting reviewing a major and cyclical that Pope Francis released about a decade ago.

And so these conversations are really important to Pope Leo.

And he had gathered these people there to be able to have a really important robust conversation about how we can carry forward some of these important agenda items that Pope Francis had left for him to do.

So those kinds of things are there that said we have a really distributed leadership model.

So the current, you president of the Conference of the Cardinals is Colonel Taglia from Philippines who was just elected recently.

He secretary of state, many others will be able to step into those roles and this is one of the things the advantages we have from having a 2000 year-old institution.

We've done transitions a number of times.

Yeah, you've had some practice Dr about 30 seconds left.

But as father mentioned, there's a family history with Pope Leo of cancer.

How significant of a factor can that be?

>> Generally for lung cancer, it doesn't play a huge part.

There is some linkage, but we actually think it's because family members shared the same environment and we think that environmental exposures probably much more important.

So.

>> If you are exposed to secondhand smoke are heavy pollution from industry that might account for more of the lung cancer risk.

Then actually mutations are passed down from individual to individual.

>> All right.

Certainly a lot of folks hoping for a speedy recovery here.

That's where we'll have to leave our
