To be retained:
- Aspirin could prevent the spread of certain cancers by reactivating immune defences.
- Its action is based on inhibition of thromboxane A2 (TXA2), a molecule produced by blood platelets.
- It is thought to be effective mainly against adenocarcinoma (colon, stomach, certain cancers of the breast and lung).
- Caution should be exercised when taking side effects: Never take any without the advice of a doctor.
- Clinical trials are ongoing to confirm these results in humans.
Could a single pill ever become a powerful ally against cancer? The future will tell us.
