Aspirin was once promoted as a cheap way to prevent cancer, and millions began taking it daily. Dr. Eric Westman reacts to the evidence behind that advice and the large ASPREE trial, which found no primary-prevention benefit and a concerning signal of increased cancer deaths among healthy older adults taking aspirin.
The video explains why observational research can mislead, how relative risk exaggerates small effects and why aspirin still has an important role after a heart attack, stroke or stent. The warning applies mainly to people taking it for primary prevention or cancer prevention without a cardiovascular history.
