Pope John Paul II's 1992 Colon Surgery: Understanding Colorectal Health

In 1992, doctors removed a tumor from Pope John Paul II's colon — publicly reported as benign. Here's what colorectal health means, in calm, accurate terms.

On screen

In July 1992, it was widely reported that Pope John Paul II underwent surgery during which doctors removed a tumor from his colon. According to contemporary news coverage, the tumor was reported to be benign following biopsy, and the operation was described as successful. His health drew worldwide attention throughout his long papacy, and this episode became a widely publicized moment in that story. (He died in 2005 of causes unrelated to this event.)

The reality

The colon and rectum make up the large intestine. According to the National Cancer Institute, colorectal cancer often begins as a growth called a polyp inside the colon or rectum. Not every growth in the colon is cancer — many are benign — but finding and removing polyps can help prevent colorectal cancer from developing. This is one reason doctors take growths in the colon seriously and examine them carefully.

Because a growth in the colon can be either benign or cancerous, biopsy and pathology are how doctors tell the difference — exactly as was reported in the Pope's case.

What the story gets right — and what to remember

The public account here is a useful reminder that a tumor is not automatically cancer. As NCI explains, tumors can be cancerous or benign, and benign growths in the colon such as polyps do not spread the way cancer does. In this widely reported case, the removed tumor was described as benign. Every person's situation is different, and news coverage of a public figure is not a substitute for personal medical advice.

Awareness, screening & prevention

Colorectal cancer is one of the cancers for which the National Cancer Institute does provide evidence-based screening information. NCI notes that finding and removing polyps can prevent colorectal cancer, and it offers PDQ information on colorectal cancer screening and on colorectal cancer prevention. Because recommended screening ages and methods can change and depend on individual risk, the best step is to ask a healthcare team what screening is right for you and when to begin.

Turning a story into something useful

A decades-old news moment can become a doorway to something practical: understanding that colon growths are common, that many are benign, and that screening can catch and remove polyps before they ever become a problem. Learning these facts, talking with a healthcare team about screening, and sharing accurate information with family are all quiet, useful acts. Free cancer education helps make that knowledge available to everyone.

Questions to ask a healthcare team

  • When should I begin colorectal cancer screening, and which test is right for me?
  • What does it mean if a polyp is found and removed?
  • How does my family history affect my screening plan?
  • What symptoms should prompt me to check in sooner?
