Recent research sheds light on the potential for a common over-the-counter medication to mitigate the risk of breast cancer recurrence following surgical procedures. A study involving mice indicates that the use of non-steroidal anti-inflammatory drugs (NSAIDs) could play a crucial role in preventing the spread of tumor cells after surgeries such as lumpectomies or mastectomies.
For years, oncologists have sought to understand the heightened risk of cancer metastasis in the 18 months following surgical intervention. A groundbreaking study published in Science Translational Medicine posits that the healing process at the surgical site may inadvertently trigger the proliferation of previously dormant cancer cells elsewhere in the body. As the immune system focuses on healing the wound, it may inadvertently allow cancer cells to escape immune surveillance, leading to the formation of new tumors.
Robert Mitchell, a biologist at the University of California, San Diego, explains, “The issue lies not in the surgery itself but in the body’s inflammatory response post-surgery, which can reactivate dormant cancer cells.” This insight has opened doors to potential preventative strategies using simple medications.
Excitingly, administering an NSAID such as aspirin before surgery and for a few days afterward could help maintain the immune response necessary to keep cancer cells in check. In a recent experiment, lab mice injected with aggressive breast cancer displayed a remarkable rejection rate of up to 90% when the immune system was activated. However, post-surgery, a significant 60% of the mice with surgical wounds developed new tumors, compared to just 10% of those without surgical intervention, reinforcing the connection between surgical trauma and cancer recurrence.
In the promising part of the study, mice that received an NSAID two hours prior to surgery and continued taking it for three days experienced a significant reduction in tumor cell activation. This finding echoes earlier research indicating that breast cancer patients who used NSAIDs for pain management after surgery had a fivefold lower risk of relapse compared to those who relied on opioids.
While further research is essential to confirm these results in human subjects, the implications are significant, particularly as metastasis is most likely to occur within 6 to 18 months after surgery. The inflammatory cells involved in this process could be managed with a simple aspirin regimen.
Mitchell emphasizes that this research does not suggest that patients should avoid necessary surgical procedures for tumor removal; rather, he hopes it will lead to clinical trials exploring the addition of NSAIDs to standard post-surgical care.

In summary, a recent study indicates that the use of NSAIDs like aspirin may significantly reduce the risk of breast cancer recurrence following surgery by preventing the awakening of dormant tumor cells. As scientists continue to explore this promising avenue, patients may one day benefit from this simple, cost-effective approach to post-surgical care.
