Why does cancer spread after surgery?

Surgery induces increased shedding of cancer cells into the circulation, suppresses anti-tumor immunity allowing circulating cells to survive, upregulates adhesion molecules in target organs, recruits immune cells capable of entrapping tumor cells and induces changes in the target tissue and in the cancer cells …
