Pope’s lung cancer diagnosis spurring greater awareness advocates say
Pope Leo XIV is making progress in his recovery after undergoing surgery for lung cancer, as his diagnosis puts a renewed spotlight on the disease and the importance of screening.
Vatican officials say the pontiff has been walking in his hospital room and eating normally following surgery.
For MaryAnn Bradley, a lung cancer survivor in St. Catharines, Ont., the Pope’s diagnosis carries special significance. Bradley said she underwent the same surgery after being diagnosed with adenocarcinoma.

“So the Pope and I have something in common. I had the same surgery,” Bradley told Global News. “I had a right upper lobectomy and it was diagnosed as an adenocarcinoma, which is the same as the Pope.”

Dr. Natasha Leighl, a medical oncologist at Toronto’s Princess Margaret Cancer Centre, said the procedure involved removing one of the five lobes of the Pope’s lungs. “There’s three on the right, two on the left,” Leighl said.

Leighl said lung cancer is the most commonly diagnosed cancer in Canada, with almost 33,000 Canadians expected to be diagnosed this year.
Signs and symptoms can include a persistent cough, shortness of breath, coughing up blood and chest pain, according to public health information cited in the script.
Doctors say early screening is the best way to improve a person’s chances.

Dr. Rosalyn Juergens, president of Lung Cancer Canada, said lung cancer screening involves a low-dose CT scan, which is performed to reduce the risk of radiation.

Juergens said screening currently focuses on people considered at high risk based on their smoking history, including whether they have smoked and how much they smoked over a period of time.
Bradley urged people who are concerned about their health not to put off speaking with a doctor.
“Please don’t wait,” she said. “Women have a tendency to wait because we have children. Our lives are busy, because we’re working full-time. Please don’t ignore (the signs).”
Bradley said she hopes the Pope’s openness about his diagnosis will help raise awareness about lung cancer around the world.
Bradley added that she believes the Pope’s lung cancer diagnosis is helping save lives by drawing attention to the disease.
