Chemotherapy for Colorectal Cancer
Chemotherapy uses drugs to destroy cancer cells. The drugs enter the bloodstream and travel through the body to the cancer cells. Chemotherapy may be used:
- Before surgery—to shrink the tumor and decrease the amount of tissue that needs to be removed
- After surgery—to kill any remaining cancer cells and decrease the risk of return
- In combination with radiation therapy to shrink tumor
- To help relieve symptoms of metastatic cancer and extend survival time
