Pope Leo XIV announced on October 11 that doctors had discovered a nodule, and then underwent a 90-minute surgery to remove the lower lobe of the right lung on October 13 and was diagnosed with lung adenocarcinoma. He was known for his healthy habits, including playing tennis every week, and was a member of the Order of St. Augustine.
The Vatican has become far more transparent in disclosing the pope's health than in the past, a culture of secrecy.
But this does not mean that Catholics are ready to face such shocking news: Roman Catholic Pope Leo XIV (Pope Leo XIV) has cancer and a large piece of tissue from his lung has been removed, even though he announced as early as Sunday (October 11) that doctors had discovered a nodule.
On Tuesday (13th), the 71-year-old Pope underwent a 90-minute operation to remove the lower lobe of his right lung and was later diagnosed with pulmonary adenocarcinoma.
Part of the shock, of course, comes from the fact that there had been little sign of any immediate concern about any imminent risk to the pope's health.
As a member of the Order of St Augustine - who placed great emphasis on cultivating good habits - the pope himself is known for his emphasis on good habits, including in the areas of health and fitness, such as playing tennis every week.
Now, with much still unknown about the pope's prognosis and what kind of treatment he may need, questions are emerging about what changes his daily routine may need to make and how long they will last.
Of course, the planned visit to South America in November, including Peru, may be affected due to the risks involved in flying soon after lung surgery and the high altitude of some of the itinerary locations. Pope Leo XIV lived in the country for more than 20 years and considered it his home.
His predecessor, Pope Francis, wrote that as he began his pontificate, he thought he might only be able to hold the post for a few years because of health problems that had plagued him throughout his life.
It was therefore clear that he was determined to push for change quickly and to implement what some considered to be quite radical church reforms at a rapid pace.
While Pope Leo XIV’s term has undoubtedly unfolded in a relatively cautious manner so far, he has quickly become a powerful, uncompromising and compassionate moral voice on the international stage.
Especially on issues such as opposing war, supporting the dignity of immigrants, and warning about the dangers of artificial intelligence, his stance is clear and distinct.
In a way, he has done what many Catholics thought would be nearly impossible, which is to begin to bring the different factions closer together in what appears to be a deeply divided church.
It is worth noting that both progressives and traditionalists often believe that his voice reflects their own values.
However, even if the surgery is successful, and there are currently no details of further treatment arrangements, speculation has begun about whether the cancer diagnosis will lead to a significant change in the pace of Pope Leo XIV's efforts to pursue what he sees as necessary reforms.
