Chinese consensus on prevention of colorectal neoplasia (2021, Shanghai).

The primary prevention is etiological prevention, which is mainly the treatment of adenoma or inflammation to prevent its development into cancer. Secondary prevention is early diagnosis and treatment of the tumor to avoid its progression to advanced cancer. Tertiary prevention belongs to the broad category of prevention, mainly for advanced CRC, through surgical treatment and postoperative adjuvant chemotherapy, radiotherapy or targeted therapy and immunotherapy to prevent tumor recurrence or metastasis.
