Officials announced an expected hospital stay of about one week.

What The Vatican Confirmed About The Diagnosis

The Holy See Press Office said an exam during surgery confirmed lung adenocarcinoma, as doctors suspected before the operation. The statement described the diagnosis as coming from intraoperative tissue review. That means pathologists looked at the tissue taken out during surgery. Officials had warned that a small, well-defined nodule was found earlier, and that action was advised. The finding turns that warning into a confirmed cancer diagnosis based on direct lab evidence.

The Vatican also stated that the Pope spent roughly three hours in the operating room and that the surgical part lasted about ninety minutes. Officials said there were no complications. The Pope had shared on Sunday that the nodule was found early and appeared localized. That helped set clear expectations before the procedure. The confirmation after surgery aligns with standard medical steps where a firm diagnosis follows lab study of removed tissue.

The Surgery And Immediate Recovery Plan

Doctors removed the lower lobe of the Pope’s right lung, which is a common operation for a cancer limited to one area. Vatican News said he would be admitted to Rome’s Gemelli Hospital on October 13 for the procedure and that he would likely remain about a week to recover. A lobectomy can help fully remove a small tumor if margins are clear and nodes are not involved. The Holy See emphasized the lack of complications after surgery.

Before the operation, the Pope told the faithful that a small, localized nodule had been found and that doctors recommended surgery. News outlets reported the plan and timing, underlining that surgeons aimed to act while the growth was still confined. This sequence is typical in lung care. Imaging can point to a likely problem, but tissue checks during surgery confirm what it is. That is how doctors tailor next steps after recovery.

What We Know Now—And What Comes Next Medically

Officials have not released the full pathology report, so the size, stage, margins, and lymph node results are not public. Those details guide choices on follow-up care. For early non-small cell lung cancer, surgeons often remove the tumor and sample lymph nodes to check spread. Staging uses tumor size, lymph nodes, and any spread to other sites to plan surveillance or added treatment if needed.

Medical references explain that doctors rely on this stepwise process. They image the chest, remove suspect tissue when needed, and let pathology define the cancer. The final stage then directs follow-up, which can range from routine scans to more therapy if risks appear higher. For now, the facts are clear: the Pope has lung adenocarcinoma, the lower right lung lobe was removed, the surgery had no complications, and recovery in the hospital is underway.
