Colon cancer is a relatively common malignant tumor of the digestive system and is a kind of colorectal cancer. There is no way to cure advanced colon cancer with surgery, so palliative chemotherapy is also common, but there is no way to determine how long you can live. However, there is no way to determine how long one can live. For those who have good treatment effect, they may survive longer, such as three years or more than five years, and this is also the case. However, most of the advanced colon cancer cases like this one have no way to do further anti-tumor treatment, but only pain relief treatment. If the advanced colon cancer has the effect of chemotherapy, together with local radiotherapy and targeted drugs to temporarily control the lesions and metastatic lesions, it is possible to survive for a longer period of time, such as more than one year, two years or even longer, but there is no way to fully judge the exact length of time, we can only see it while treating.
