What role does the immune system play in cancer treatment following surgery?

The immune system plays a vital role in cancer treatment following surgery, primarily by helping to destroy any remaining cancer cells that may not have been removed during the surgical procedure. After surgery, the body’s immune response is crucial for identifying and eliminating these residual cancer cells, which could potentially lead to recurrence or spread of the disease. This post-surgical immune activity can be enhanced through various therapies, such as immunotherapy, which aims to strengthen the immune system’s ability to target and kill cancer cells.

The idea that the immune system has no role after surgery is misleading, as it is actively engaged in the postoperative phase to prevent recurrence. While the regeneration of blood cells is indeed a function of the immune system, it does not encompass the broader and more critical role of targeting cancer cells specifically. Additionally, the immune system does not delay wound healing; rather, a well-functioning immune response is necessary for proper healing and recovery following surgical interventions.
