Recent findings have shed light on the potential spread of breast cancer post-surgery and how a straightforward solution may exist. A study conducted on mice indicates that a common and inexpensive medication could play a significant role in preventing the dissemination of tumor cells following procedures like lumpectomies or mastectomies.
Historically, medical professionals have sought to understand why breast cancer patients are particularly susceptible to the spread of cancer within the first 18 months post-surgery. A new study, published in Science Translational Medicine, suggests that the body’s healing response to the surgical site might be a crucial factor in triggering the spread of cancerous cells. As the immune system focuses on healing, it may inadvertently neglect to combat cancer cells that are circulating in the body, allowing them to proliferate and potentially form new tumors. Dr. Alex Carter, a biologist involved in the study, explained, “It’s not just the surgery itself; it’s the body’s wound healing process that is stimulating the growth of previously dormant cancer cells.”
Fortunately, the solution might be as simple as taking aspirin. This anti-inflammatory drug, when administered before and after surgery, could effectively hinder the spread of cancerous cells and prevent post-surgical tumor growth. Research involving laboratory mice has shown promising results: when given an NSAID two hours prior to surgery and twice daily for three days afterward, the mice exhibited a significant reduction in the activation of tumor-forming cells. This aligns with earlier findings from a 2012 study, which demonstrated that breast cancer patients using NSAIDs for pain management after surgery had a fivefold lower rate of cancer recurrence compared to those on opioids.
In the mouse study, a substantial number of animals that underwent surgery showed continued tumor growth, while those that did not have surgery experienced significantly lower rates of tumor development. This correlation between surgical intervention and cancer regrowth underscores the importance of managing the inflammatory response post-operation.
However, further research is necessary to ascertain whether these findings will translate effectively to human patients. Insights from this study reveal that inflammatory cells from the bone marrow can impair the immune response, a process that could potentially be mitigated through a simple course of aspirin. Dr. Carter emphasizes that their research is not suggesting patients forgo necessary surgeries, but rather aims to encourage future studies on incorporating NSAIDs into post-surgical care.

In summary, new research indicates that the healing process following breast cancer surgery may activate dormant tumor cells, but a simple regimen of NSAIDs like aspirin could potentially curb this effect, offering hope for improved post-surgical outcomes.
