Millions take aspirin to prevent colon cancer. A major review says don’t count on it
A Cochrane review found that daily aspirin does not reliably prevent colorectal cancer in people at average risk; any protective effect is weak and may take more than a decade to appear. The analysis also found serious bleeding risk begins immediately, including with low-dose aspirin, and experts recommend individualized prevention decisions rather than routine use.
Why it mattersCochrane review: aspirin shows weak colorectal cancer prevention and immediate bleeding risk; avoid routine low-dose use.
