It is possible to cure colorectal cancer. According to the different stages of colorectal cancer, the prognosis is obviously different, and the earlier it is detected and treated, the better the prognosis is. Patients with middle or advanced colorectal cancer, with lymph node metastasis or tumor invading organs, have poorer prognosis. Clinically, the staging and treatment of colorectal cancer are mainly as follows: 1. Stage I colorectal cancer patients with radical surgery have a better prognosis and the 5-year survival rate can reach more than 90%; 2. Stage II colorectal cancer patients with radical surgery or radical surgery plus adjuvant chemotherapy can have a 5-year survival rate of 60%-80%; 3. Stage III colorectal cancer patients with radical surgery plus adjuvant radiotherapy can have a 5-year survival rate of In recent years, patients with liver metastasis, non-metastasis and ovarian metastasis of colorectal cancer, if the metastases are resectable or potentially resectable, they can still achieve better treatment results through direct surgery or chemotherapy plus targeted therapy followed by surgery. In daily life, colorectal cancer patients should pay attention to more rest, maintain a positive and optimistic attitude, reduce psychological pressure, and eat reasonably. Regularly review tumor markers, whole abdomen enhanced CT, lung CT and colonoscopy, so that if there is recurrence, they can intervene in treatment as early as possible to get better results.
