Urinary Infections May Signal Cancer Risk After 50
Swedish research indicates urinary tract infections might signal cancer risk in adults over 50. The large-scale study analyzed nearly 3.6 million people but researchers caution against overinterpreting the findings. Most UTIs remain easily treatable without indicating serious health issues.

A new Swedish study suggests urinary tract infections could indicate cancer risk in people over 50. Researchers found possible links between UTIs and urinary tract or gynecological cancers. The study analyzed nearly 1.9 million women and 1.7 million men between 1997 and 2018.
Filip Jansåker, a specialist physician and researcher at Lund University, said urinary infections might serve as risk markers. He clarified the study only shows indications, not strong conclusions. Jansåker emphasized most urinary infections remain easily treated conditions that need no further investigation.
Why does this matter for people over 50? The research team tracked how many participants developed UTIs and later received cancer diagnoses. They used primary care data spanning two decades from Swedish healthcare records.
The study's scale makes it noteworthy, but the findings require cautious interpretation. Many people experience urinary infections without developing cancer. Still, the potential connection warrants attention in routine medical checkups for middle-aged and older adults.
Sweden's comprehensive healthcare database enables such large-scale research. The country maintains detailed medical records that help researchers identify health patterns across populations. This study demonstrates how long-term data can reveal potential health connections that might otherwise go unnoticed.
