The tumor has metastasized in multiple places in the advanced stage of cancer. The survival time of patients has individual differences, which are greatly related to the type of disease, the patient’s age, the nutritional status of the body, whether there are other diseases, and whether they are effectively treated. Clinically, the average tumor is advanced and the general survival time is about six months to one year. In case of pancreatic cancer with higher malignancy, the survival time is shorter, usually about 1-3 months. Patients with advanced lung cancer and breast cancer that can be treated with effective drugs have a relatively long survival time, and clinically there are patients who are already in the advanced stage of tumor at the time of discovery but still have a survival time of more than five years. Therefore, if patients are found to have advanced tumor, they should still be treated actively to improve their symptoms in order to improve their survival quality.
