Earlier on Wednesday, the Vatican said he was "progressing as expected" and had spent a peaceful night in hospital.
In a statement, he said: "As you know, I have been unable to be among you during these days. I thank you warmly for your prayers and for the work you have done together. Your sharing of experiences and attentive listening are indeed a gift to the whole Church.
"I am especially grateful to the families who have spoken of their joys, struggles and hopes."
Leo, 71, had part of his right lung removed during Tuesday's procedure and he was diagnosed with adenocarcinoma - the most common form of the disease.
The Pope's surgeon and his personal doctor said the 90-minute surgery at Rome's Gemelli University Hospital went smoothly.
The entire lower lobe of his right lung was cut away to try to remove all traces of cancer. Humans have three lobes in the right lung and two in the left.
Pre-operative tests suggested adenocarcinoma, and this was confirmed during the operation, the Vatican said.
Well-wishes for the Pope have poured in from around the world. Sky News understands the King will write privately to the pontiff following his diagnosis.
The Pope is scheduled to visit Uruguay, Argentina and Peru next month.
Church officials in Argentina, the homeland of Leo's predecessor Pope Francis, urged parishioners to put the pontiff's well-being ahead of their excitement over the country's first papal visit in four decades.
Leaders across Argentina's deep ideological divide, from right-wing president Javier Milei to left-wing governor of Buenos Aires, Axel Kicillof, joined in wishing the pope a speedy recovery.

In Chiclayo, one of Peru's largest cities, excitement over Leo's anticipated homecoming turned to apprehension after his diagnosis.
"Because of the affection that we feel for the Holy Father, who is also our bishop, we're worried about his health and about what will come next," said the Rev. Elmer Uchofen, who recalled how the future pope helped secure oxygen production plants during the COVID-19 pandemic, waded through mud in rubber boots to aid flood victims and celebrated Mass with prisoners in Chiclayo.
In Uruguay, Cardinal Daniel Sturla, the archbishop of Montevideo, said "First, let us pray that he comes."
Pope Leo XIV is expected to remain in hospital for about a week and his diary has been cleared until 20 October.
Rooney, whose bestselling novels include Normal People and Conversations With Friends, said that the sale and publication of her books in the UK could "constitute a serious criminal offence".
The Irish author, 35, previously said she would donate earnings from her work to Palestine Action, which has a stated goal of "ending global participation in Israel's genocidal and apartheid regime".
The ban, which began on 5 July 2025, made membership of, or support for, the direct-action group a criminal offence punishable by up to 14 years in prison.
Her publisher, Faber, said it cannot sell the Irish author's novels in the UK because the ban "has led to circumstances where Faber cannot pass on UK earnings to Sally Rooney for her work".
Faber's decision to withdraw Rooney's books from sale in the UK was made "with my full agreement", she said in a statement.
She said: "In July 2025, the direct-action protest group Palestine Action was proscribed as a terrorist organisation in the UK.
"The following month, I wrote an opinion piece expressing my intention to go on supporting Palestine Action, which is not a proscribed or otherwise prohibited group here in the Republic of Ireland.
"As a result, the fulfilment of contracts to publish my work in the UK could now constitute a serious criminal offence."

Rooney's books also include Beautiful World, Where Are You? and Intermezzo.
Palestine Action co-founder Huda Ammori said: "Sally Rooney being unable to publish her work in the UK marks a new low in the escalating assault on free speech caused by the proscription of Palestine Action.
"A world-renowned author fearing arrest and being forced to remove her books from our bookstores, exposes the chilling consequences of this authoritarian law, which has been used to make over 3,700 arrests for simply holding seven word signs."
Ammori called on Prime Minister Andy Burnham to overturn the ban, adding "this is a political choice, and one with profound consequences for freedom of expression in this country".
Thousands of people have been arrested for alleged support of the organisation since it was banned in July last year.
In September 2025, Rooney cancelled a trip to London to accept the Sky Arts Award for literature for fear of an arrest.
It comes as Donald Trump posted a widely shared clip of the attack involving William Chapman on social media.
Mr Chapman's family said the 23-year-old had a "significant mental illness" and they are "utterly devastated" by his death.
He was killed after entering the tiger enclosure at Yorkshire Wildlife Park in Doncaster on Saturday.
Mr Trump posted a video of Mr Chapman and the tiger on his Truth Social platform on Tuesday evening, alongside the caption: "Don't ever mess with nature!"
The US president later published an AI-generated clip of himself chasing and wrestling the tiger.
Mr Chapman's family statement - also released on Tuesday night - asked people to stop sharing such content, which they said was causing "severe distress at an exceptionally vulnerable time".
Downing Street said people should respect the views of Mr Chapman's family over the sharing of footage but declined to comment directly on Mr Trump's actions.
The prime minister's official spokesman said: "I think obviously the family have made their position clear. Of course, we respect that position."
But he added: "I'm not going to comment on the president's social media channels, he's got a press secretary who can speak to that."
Family pay tribute
Mr Chapman's family described him as a "bright, warm and engaging young man" who was "dearly loved".
"Sadly, William suffered from significant mental illness over a number of years and was consequently prescribed strong medication," they added.
"It will be for the coroner to decide what part this played in his death. We would ask everybody to respect that process."
Mr Chapman was a child actor who appeared in ITV's May Contain Nuts in 2009, alongside Harry Potter star Shirley Henderson, and in the BBC's True Stories series in 2012.
The Jackie Palmer Stage School in High Wycombe, where he was a former student, paid tribute on Instagram.
It said it was "deeply saddened" and Mr Chapman would "be remembered with great fondness".
"We loved watching William grow, both as a person and as a performer, during his time with us," a spokesperson said.
"It was a privilege to be part of his journey, and he will be remembered with great fondness by everyone who had the pleasure of knowing him," the school added.
"William will be truly missed, and he will always hold a special place in our hearts."

Mr Chapman filmed himself approaching the tiger as it lay on a wooden platform in the moments before the attack, according to footage on his social media.
The person filming can be heard breathing heavily as distant voices shout "Oh my God" and "seriously".
Police confirmed Mr Chapman was visiting the park alone.
'Its eyes locked on to something'
Eyewitnesses said people were frantically telling Mr Chapman to "play dead", but he didn't appear to understand. He was heard telling the tiger to "stop being naughty".
One witness said he was "dancing with headphones on" shortly before climbing into the enclosure.
Anthony Hunt, who was there with his girlfriend, Scarlet, said they were taking pictures of the tiger when they saw its composure change and head turn.
"Its eyes locked on to something in the enclosure. We thought maybe he's getting fed," said Mr Hunt.
"When Scarlett was taking photos, we suddenly saw in the camera lens that a guy had entered the enclosure."
The victim "bowed down, on all fours, started praying, and looking up at the sky," he said.
"The tiger was still on the landing at this point" - but then "leapt off the landing, and sniffed the guy".
The wildlife park - which has confirmed the tiger will not be put down - remained closed on Wednesday.
The local council has launched a health and safety investigation, while an inquest into Mr Chapman's death is due to open in Doncaster on Thursday.
Tributes have been paid to the "two beautiful children" who died alongside parents Philip and Kim English in the house fire.
Police said they believe the property was attacked by a person or persons unknown, and that the fire was started deliberately.
A murder investigation was launched after the blaze in Birchwood, Waterford City, shortly after 5am on Tuesday.
James English, the uncle of Philip English and the godfather of one of the children who died, said: "Whoever did it, he better feel ashamed of himself."
"Well, whoever knows, they'd want to turn up and own up whoever done it," he added.
"At the end of the day, we have a loss of family now, wiped out. So please, whoever done it, own up, be a man."
Relatives have launched an appeal for donations to support the family during an "incredibly difficult time", writing in a tribute that Philip, Kim, Callum and Jayden would "forever be loved and never forgotten".
"Our beloved Phillip and Kim English, along with their two beautiful children, Callum and Jayden, both under the age of 10, tragically lost their lives in a house fire," they said.
"There are no words to describe the heartbreak of losing four precious lives in such devastating circumstances."
Two other siblings are "also currently in hospital in critical condition", the GoFundMe page said.
Johnville Football Club, where Callum played for five years, said the community was "absolutely heartbroken and devastated" by the loss.
"Kim and Philip were familiar and friendly faces around our club, always there supporting Callum at his matches," the club said on Facebook.
The club said a vigil will be held at 5pm on Wednesday at the Sacred Heart Church in The Folly.

Caroline Douris, the principle of the school of the two children, who stopped to leave flowers at the house described one of the boys as "a lovely young fella".
She said the other "lights up the school every day with that smile as he comes through the door".
Six psychologists have been allocated to local schools to help support children.
'Extremely shocking'
Irish Prime Minister Micheal Martin said the murders were "extremely shocking" and all support would be provided to police.
Officers said the investigation is "intense in nature and very active", with searches being carried out in several properties in Waterford on Tuesday evening.
Devices and vehicles have also been seized for technical examination.
No arrests have been made.
Chief Superintendent Anthony Pettit said: "There are people in the community who know the person or persons who carried out this arson attack in which four people have been murdered."
Anyone who was in the vicinity of Birch Avenue, Birchwood, between 4.30am and 5.30am on Tuesday or was driving in the wider area at that time has been urged to contact police.
Eleanor Lyons and children's charity ECPAT UK warned in a report published on Wednesday that there were fewer than 20 convictions in cases flagged for both child abuse and trafficking.
A total of 7,045 children were referred as potential victims in 2025, said the report, released to mark Anti-Slavery Week.
More than six in 10 were British nationals, and the report warned the figures may only be the tip of the iceberg.
Thousands of other children may be going unidentified, with social services recording more than 30,000 assessment episodes involving criminal or sexual exploitation in England alone, the study said.
In England, that total included 16,250 assessment episodes involving child criminal exploitation, 12,400 involving child sexual exploitation and a further 2,250 involving trafficking in the year to March 2025, according to figures from children's social services.
The report said many end up in county lines operations, being exploited by criminal gangs to transport drugs, commit theft and other offences, while others face sexual exploitation, forced labour and abuse within homes and workplaces.
Ms Lyons told Sky News that youngsters are being "sexually exploited by criminal gangs or held in county lines groups", and the majority are British boys.
The report cautions that the figures are not directly comparable with trafficking referrals and may include repeat assessments of the same child.
But, despite the alarming rise in referrals, there were only 17 convictions in cases flagged as involving both modern slavery or trafficking and child abuse, down from 38 in 2024, the report claims, quoting analysis of Crown Prosecution Service data.
Ms Lyons told The News Hour With Mark Austin the overall effect is "children across the country being robbed of their childhood".
When children are trafficked and exploited, they are being "sexually exploited by criminal gangs or held in county lines groups, forced to deal drugs right across the country. And sadly, we're seeing that number rise every single year, with more and more British kids being exploited and harmed", she said.

Ms Lyons said she has "spoken to children who are exploited from the age of eight", and "every year we're seeing the age get younger and younger of children who are being exploited".
"The statistics and the figures show that whilst there are children of all nationalities, the majority are British boys."
Perpetrators, though, are becoming "more ruthless, going younger and younger and even targeting children in primary schools, grooming them, offering them maybe gifts or offering to buy them lunch, and then following up the next day with threats, with violence, and forcing them to carry out criminal acts on the gang's behalf".
She called on ministers to do more to prevent harm happening to children across the UK, including establishing a national child exploitation strategy, improving early identification and prevention, and strengthening police investigations and prosecutions.
Sky News has approached the Home Office for comment.
