Each year, bowel cancer claims roughly 900,000 lives, making it one of humanity's most persistent and lethal burdens. A new analysis now suggests that Helicobacter pylori — a bacterium long implicated in stomach cancer — may quietly account for approximately one in five of those cases worldwide, weaving a familiar thread between microbial life and human mortality. The finding does not yet confirm causation, but it opens a door that researchers believe warrants urgent, rigorous investigation, particularly in regions where the bacterium is common and medical resources are scarce.
