Pope Leo XIV’s release from the hospital after recently undergoing lung cancer surgery carries a significance that extends well beyond the ancient walls of the Vatican.
The pope’s diagnosis and positive prognosis offers a high-profile example of the survivability of one of America’s deadliest cancers when it is discovered early—which happens too infrequently in Mississippi, where lung cancer has killed residents at some of the highest rates in the nation for decades.
“Many prayers for Pope Leo,” one person wrote on the Catholic Diocese of Biloxi’s Facebook page after the pontiff underwent surgery on Oct. 14, 2026. Another prayed for his “quick healing and recovery.” For believers, those prayers so far appear to have been answered.
Doctors discovered a small, localized nodule in Pope Leo’s right lung and determined that it was malignant but had been caught at a “very early stage,” according to the Vatican. Surgeons at Rome’s Gemelli Hospital removed a portion of the lung while confirming the cancer was lung adenocarcinoma, the most common form of lung cancer.
The operation lasted about 90 minutes and was completed without complications. By Oct. 16, the Vatican reported, the pope was walking, eating normally and performing daily activities independently, while a chest X-ray showed “good recovery” of the affected lung following surgery.
The pope’s relatively swift sequence of detection, diagnosis and potentially curative surgery while the cancer was still localized is a particularly significant example for Mississippians facing similar issues.
For more than two decades, Mississippi has recorded some of the worst lung cancer outcomes in the United States, according to federal cancer data. A June 2026 report from the Centers for Disease Control and Prevention and the National Cancer Institute showed the state continues to have among the nation’s highest rates of new lung cancer cases, as well as the third-highest mortality rate and second-lowest five-year survival rate.
The American Lung Association’s most recent “State of Lung Cancer” report estimated 68.7 new cases for every 100,000 Mississippi residents, compared with 52.8 nationally.
Survival is similarly poor. Just 24.1 percent of Mississippians diagnosed with lung cancer survive for at least five years, compared with 29.7 percent nationally. The state was the only one that failed to report lung cancer incidence data from 1999 through 2002 and remains one of two states that do not report data showing the stage at which lung cancers are diagnosed.
Nationally, about two-thirds of people whose non-small cell lung cancer is diagnosed while it is still localized survive for at least five years, according to the American Cancer Society. When the cancer is not discovered until it has spread to other parts of the body, that figure falls to about 10 percent.
Black men have historically recorded Mississippi’s highest lung cancer incidence and death rates, while Black lung cancer patients overall are less likely than white patients to have their cancer detected early or to undergo surgery, noted a 2016-2020 study by the Mississippi State Department of Health.
The reasons for the disparity are complex. Black Americans are less likely to get an early diagnosis and less likely to receive potentially curative surgery. Researchers have also identified differences in access to care, screening eligibility and environmental exposures. Smoking alone does not explain the unusually high lung cancer rate among Black men.
Nowhere in Mississippi does the Pope’s experience resonate as strongly as it does in Harrison County. The Gulf Coast county has more Catholics than any other county in the state, according to the most recent comprehensive county-level U.S. Religion Census. It is also home to the Diocese of Biloxi, headquartered at Nativity of the Blessed Virgin Mary Cathedral in downtown Biloxi.
There’s no evidence that Catholics suffer more or less from lung cancer than other people, yet Harrison County stands out for another reason: Its residents develop lung cancer at a rate dramatically higher than Americans overall. In the middle part of the last decade, Harrison County had the highest rate of lung cancer of any county nationwide.
The latest federal county-level figures show Harrison County recorded 77.4 new lung and bronchus cancer cases per 100,000 residents annually from 2019 through 2023, according to National Cancer Institute figures. While the county still recorded the most annual lung cancer cases in Mississippi during those years, several other counties have a higher incidence rate per 100,000 residents. Harrison County averaged 199 per year.
The disparity is even greater when measured in deaths. From 2019 through 2023, Harrison County recorded 49.2 lung cancer deaths per 100,000 residents, compared with 31.5 nationally, a mortality rate about 56 percent higher than the country as a whole.
Pope Leo benefited from immediate access to some of the best medical care in the world. But the most important advantage he had came before he entered the operating room. His cancer was found while doctors could still do something decisive about it.
