Scientists at the University of Cambridge have made a surprising discovery: a widely used pain reliever may help reduce cancer metastasis.
While the findings are promising, researchers stress that more studies are needed before considering aspirin as a cancer treatment.
A Chance Discovery Leads to a New Hypothesis
Researchers were studying how the immune system responds to cancer when they unexpectedly stumbled upon a possible link between aspirin and reduced metastasis. This “aha moment” shifted the focus of their study entirely.
What Is Cancer Metastasis?
When cancer cells spread from their original location to other parts of the body, they form secondary tumors called metastases. Stopping this process is one of the biggest challenges in cancer treatment.

Aspirin’s Surprising Effect on Cancer Spread
In mouse studies, researchers found that aspirin appeared to lower the number of metastases. This discovery could have major implications for future cancer treatments if similar effects are observed in humans.
How Aspirin Might Work Against Metastasis
Aspirin seems to interfere with a substance in the blood called TXA2, which can suppress immune cells that fight cancer. By reducing TXA2 levels, aspirin may allow the body’s natural defenses to function more effectively.
The Role of T-Cells in Fighting Cancer
T-cells are the immune system’s natural cancer killers. The study suggests that when TXA2 is present in high amounts, it can weaken T-cell activity, allowing cancer cells to spread more easily.
A Drug with a Long History
Aspirin, derived from salicylate found in willow bark, has been used for centuries to relieve pain and inflammation. It’s already known for its heart-protective properties, and now it could have another unexpected benefit.

The Dangers of Rushing to Conclusions
Despite these findings, scientists caution against using aspirin as a cancer treatment just yet. The drug can have serious side effects, including stomach ulcers and bleeding risks, making self-medication a dangerous choice.
More Research Is Needed
The current study was conducted in mice, and while the results are intriguing, human trials are essential before determining whether aspirin could be a safe and effective cancer-fighting tool.
Published in a Leading Scientific Journal
The findings have been published in Nature, one of the most respected scientific journals, highlighting the significance of this discovery in the medical research community.
A Step Toward Future Cancer Treatments
If further research confirms aspirin’s potential in preventing metastasis, it could pave the way for new, affordable cancer treatments. However, until then, patients should rely on proven medical therapies
