After colon cancer surgery, the survival time is about 2-5 years. Colon cancer is caused by pelvic and abdominal metastasis, and when it reaches advanced stage, it means that the situation is already serious, so surgery can only prolong the patient’s survival time as much as possible and reduce the patient’s pain to a certain extent, after which chemotherapy treatment is needed, which requires 6-8 cycles of chemotherapy. After colon cancer surgery, the patient can continue to survive for 2-3 years, but if the surgery is successful, coupled with post-operative targeted drug therapy and good recovery, and the organ function is still excellent, the patient can survive for about 5 years, but there are also exceptional cases of clinical cure, which can live for more than 5 years. Therefore, once the symptoms of colon cancer have reached advanced stage, it is important to take active treatment to prolong the survival time as much as possible.
