Variable efficacy according to the types of cancer
Aspirin would not be effective against all cancers. It seems to be particularly beneficial for adenocarcinomas, a type of common cancer that includes:
Colorectal cancer
Gastric cancer
Certain breast and lung cancers
On the other hand, it appears to have a limited effect on other types of cancers that do not make as much use of T cells in their metastatic process.

Be careful, no self-medication.
Before you run to buy aspirin, be careful. While these results are promising, they have so far been observed only in mice. In addition, aspirin can cause serious side effects, including bleeding, ulcers or an increased risk of some strokes. It is therefore essential not to take it without medical advice.
Clinical trials are ongoing to confirm these results in humans and to determine the optimal dose to prevent metastases while minimising risks.
