Progressive colon cancer usually refers to stage II and stage III colon cancer. Colon cancer can be divided into early stage colon cancer, that is, stage I colon cancer, where the tumor is relatively small, the invasion of the colon is relatively shallow, and there is no lymph node metastasis, so regular follow-up after surgery is possible and chemotherapy is not needed. Progressive colon cancer includes stage II and III colon cancer, which usually can be radically treated by surgery, that is, the tumor can be completely removed and the lymph nodes around the tumor that may have metastasis can be completely cleared, after which the specimen should be sent to pathological examination to further confirm whether it is stage II or stage III colon cancer. After surgery, chemotherapy is recommended because there may be residual cancer cells in the body, and chemotherapy can further prolong the overall survival of the patient.
