Here are what several medical experts told AFP about the surgery and diagnosis.

Pulmonary adenocarcinoma, the type of tumour removed from the Pope, generally comes from “a primary cancer”, said Dr Juanita Mora, a medical spokesperson for the American Lung Association.
asserted
Mora → remove → Association
She told AFP that “is a good thing” because it means the tumour is from lung cancer instead of generating from the spread of another cancer.

There are two main types of lung cancer: “small cell” cancers, which spread aggressively and make up about 10 to 15% of diagnoses, and “non-small cell” cancers, which make up the vast majority.
asserted
which → be → majority
“Adenocarcinoma is the most common kind of what’s called non-small cell lung cancer,” David Spigel, a medical oncologist specialising in lung cancer research at Nashville’s Sarah Cannon Research Institute, told AFP.

David Carbone, director of the Oncology Center at Ohio State University, noted that while smoking is the most well-known risk factor for a lung cancer diagnosis, “most lung cancers that we diagnose today are in people who haven’t smoked, or (stopped) many years ago”.

Lung cancer is the top cause of cancer death worldwide, according to the World Health Organization (WHO), but the prognosis can vary significantly depending on the type of lung cancer and how advanced it is when first detected.

“When we look at five-year survival rate from lung adenocarcinoma, and it’s nicely localised, the rate is approximately 63% to 67%,” Mora said.
asserted
Mora → look → adenocarcinoma
“But if we catch it early, it becomes 80% to 98%, especially after surgical removal.”
asserted
it → catch → removal
In such a case, the patient “will achieve a cure and never have their life threatened by cancer”, Spigel added.
asserted
Spigel → achieve → cancer
A standard procedure
Pope Leo XIV announced the presence of the lung nodule on Oct 11, saying it had been “detected at a very early stage” and was localised.
asserted
it → announce → stage
The Vatican said “the lower lobe of the right lung was removed” during the Oct 13 operation to remove the mass.

“He had part of his right lung taken out, which is the standard procedure,” Carbone told AFP.

“There’s a lot of reserve in the lung, and people can have an entire lung removed and live a normal life,” he added.
asserted

“I would expect that he’d be back to completely full level of activity very soon.”
What now?
The question now is whether Pope Leo XIV will need additional treatment such as chemotherapy or radiation.
asserted
XIV → expect → chemotherapy
According to the experts consulted by AFP, the answer will depend on several factors, such as the size of the cancerous mass removed, how aggressive it was, its genetic characteristics, and whether or not it has spread.
uncertain
it → accord → mass
A Vatican source indicated that additional testing is underway.

For Carbone, the fact that the Pope has already undergone surgery is encouraging.
asserted
Pope → undergo → surgery
“Because if it had spread to, for example, the lymph nodes in the centre of the chest, he would have had some treatment before surgery, which he didn’t have,” he explained.
asserted

“They really do go straight to surgery only for the earliest stage tumours, which makes me think this was a very early stage tumour, and has a quite good prognosis.”
asserted
this → go → prognosis
He stressed that treatment for lung cancer has improved considerably over the past few decades, “and the prognosis is better than ever.
