Scientists from the United Kingdom, Italy, Taiwan, and France have confirmed the potential positive effect of aspirin on reducing metastasis. In experiments conducted on mice, the drug was shown to prevent cancer cells from a primary tumor from spreading to other organs.
Animals that received aspirin were less likely to develop metastases in breast, colorectal, and skin cancers. Notably, tumor cells did not spread to vital organs such as the lungs and liver.
According to oncologist Evgeny Cheremushkin, aspirin is known not only for its anti-inflammatory and fever-reducing properties but also for its ability to prevent platelet aggregation and blood clot formation. This mechanism plays a key role in slowing the spread of cancer cells.
“If a cancer cell enters the bloodstream but cannot attach to vessel walls and penetrate tissues, metastasis will not occur. Aspirin helps prevent this process,” the specialist explained. This is why aspirin is sometimes considered a supportive method that may improve prognosis by limiting the spread of tumor cells.
However, the doctor cautions against self-medication. While aspirin may have supportive benefits, modern oncology offers more effective treatments specifically designed to prevent metastasis. Aspirin should not replace standard therapies and must be used only under medical supervision, as it has contraindications and potential side effects.
The expert also emphasized that people without a cancer diagnosis should not take aspirin for prevention. Like any medication, it should only be used when medically necessary and for a defined period, as prolonged use can reduce effectiveness and increase the risk of adverse effects.
