**Cambridge, UK** – A new study published in *Nature* reveals a potential new role for aspirin in the fight against cancer. Researchers at the University of Cambridge have discovered that aspirin disrupts the protective shield cancer cells use to evade the immune system, potentially slowing or preventing the spread of the disease – a process known as metastasis.

Metastasis is responsible for the majority of cancer deaths. Cancer cells, escaping the original tumor, coat themselves in platelets, effectively camouflaging themselves from the body’s T-cells, which would normally destroy them. Aspirin, by reducing a molecule that platelets use to suppress immune activity, weakens this shield, allowing T-cells to effectively target and eliminate the rogue cells.

While previous studies hinted at a link between aspirin use and improved cancer survival, this research explains the underlying mechanism. The findings suggest aspirin could be beneficial after treatments like surgery, targeting cancer cells that have already spread. However, researchers stress that aspirin is not a cure and carries risks, including increased internal bleeding due to its blood-thinning properties.

The study, conducted on mice, requires further clinical validation in humans. Several clinical trials are underway to determine the efficacy and optimal use of aspirin in cancer treatment, identifying which patients would benefit most and for which cancer types. While aspirin is already recommended for cancer prevention in high-risk individuals in some countries, experts caution against its immediate use as a cancer treatment without further research.

The research also opens doors for developing new, targeted therapies that mimic aspirin’s benefits without its side effects. Researchers are exploring similar effects with other anti-platelet drugs, potentially leading to safer and more effective treatments in the future. While a universal cancer cure remains elusive, this discovery offers a promising avenue for improved cancer treatments and potentially saves countless lives.
