Newsweek – A recent study has revealed that an aspirin a day may stop cancer from spreading.
In 2025, over 2 million new cancer cases are expected in the U.S., with more than 618,000 deaths—about 1,700 per day—according to the American Cancer Society.
The research, conducted by scientists at the University of Cambridge in England, discovered the common drug could reduce metastasis—the spread of cancer cells from the original tumor to other parts of the body—by stimulating the immune system.
Professor Rahul Roychoudhuri, from the University of Cambridge, who led the study, told Newsweek: “I believe the appropriate message for cancer patients is one of cautious optimism balanced with medical guidance.
“Aspirin is indeed low-cost and widely available, but it’s not without significant risks. Long-term aspirin use is associated with gastrointestinal toxicity including peptic ulceration and upper gastrointestinal bleeding.
“There is also an increased risk of hemorrhagic stroke, particularly in older individuals. The risk-benefit calculation varies substantially between individuals based on age, comorbidities, and concurrent medications.”
Roychoudhuri advises patients interested in aspirin therapy to discuss it with their oncologist or family practitioner, who can evaluate the potential benefits against these risks in their specific case.
Clinical trials are underway to determine how to use it safely and effectively to prevent cancer from spreading.
Studies of people with cancer have previously found that those taking daily low-dose aspirin have a reduction in the spread of some cancers, such as breast, bowel, and prostate cancers, leading to ongoing clinical trials.
However, until now it wasn’t known exactly how aspirin could prevent the spread …
