Colon CA is a shorthand for colon cancer, which is a malignant tumor occurring in the epithelial lesions of the colon mucosa. How long colon cancer can survive is related to the severity of the disease and treatment means and other factors: 1. Under the treatment of early stage colon cancer patients with surgery, the 5-year survival rate can reach 90%, but there is a certain risk of recurrence; 2. For patients with mid- to late-stage colon cancer, the 5-year survival rate is 50%-70% after a combination of chemotherapy, radiotherapy and targeted therapy with surgery as the main treatment. For patients with localized mid- to late-stage colon cancer who cannot undergo surgery for various reasons, chemotherapy and targeted therapy are the core therapies. The survival period of most malignant tumors will be relatively short after metastasis occurs, but if the metastasis of colon cancer is relatively limited, a longer survival period can be obtained after active treatment. The patient’s mentality is also a very important part in the treatment of malignant tumor, do not give up easily, and actively deal with the difficulties to a certain extent is beneficial to the treatment.
