Can colon cancer be cured by surgery in the middle and late stage?

Surgical treatment can only cut the tumor visible to the naked eye, but there may be some tiny lesions and metastatic lesions invisible to the naked eye in the middle and advanced colon cancer, but there is nothing we can do. We generally recommend conservative treatment, and postoperative combined biotherapy is a relatively mild treatment mode, which can not only effectively remove the residual tiny lesions and metastatic lesions in patients, but also significantly reduce postoperative recurrence. It can also obviously accelerate the recovery of patients' physical function after operation and improve their own disease resistance.
