  • Chemotheraphy: Drugs are used after surgery to eliminate any remaining cancer cells or combined with radiation therapy to shrink tumor before surgery. It can also alleviate symptoms in unresectable or metastatic rectal cancer.
  • Targated drug therapy: Focuses on specific cancer cell abnormalities to induce cell death. Often combined with chemotherapy for advanced rectal cancer patients.
  • Combination of radiation and chemotherapy: Enhances radiation's effectiveness in larger or high-risk cancers. Administered before surgery to facilitate less invasive procedures or after surgery to reduce recurrence risk. It can also be used as a primary treatment for advanced cases.
