Whether the colon cancer can be cured after recurrence is related to the severity of the disease and cannot be generalized. If the recurrence is a single recurrence, there is a possibility of cure; if the recurrence shows extensive tumor metastasis, the cure rate is low. Colon cancer can present symptoms such as abdominal pain, blood in stool, abdominal mass, etc. If the recurrence of colon cancer is a single recurrence, and the tumor has not invaded other organs and important blood vessels, it can be treated by surgery, radiotherapy, etc., and the possibility of cure is still there. If the colon cancer recurrence is more serious and extensive metastasis of the whole body occurs, the cure rate is lower, and the life span can be prolonged by chemotherapy and radiotherapy. It should be noted that in case of recurrence of colon cancer, one should seek medical treatment in time and follow up on schedule after being discharged from hospital to prevent the condition from worsening.
