Recent findings suggest that aspirin may play a significant role in cancer treatment by preventing metastasis. The mechanism involves the limitation of thromboxane A2 (TXA2), which is known to suppress immune responses. By inhibiting TXA2, aspirin could enhance immune system activity against cancer cells, potentially reducing the risk of cancer spread. This insight opens the door for further research into aspirin's use as a prophylactic agent in cancer therapies. The discussion in the comments highlights excitement and curiosity about how common over-the-counter medications can intersect with cancer treatment and immunity enhancement.
