The exact length of life for advanced cancer is related to many factors, such as the specific type of cancer, whether effective treatment is adopted, patient’s physical condition, etc., which need to be analyzed on a case-by-case basis. In the case of advanced papillary thyroid cancer, even if metastasis has occurred, the 5-year survival rate may reach 80% with active treatment. In the case of advanced breast cancer, bone metastasis and lung metastasis may have occurred, but if effective treatment can be provided, the 5-year survival rate of the patient is relatively large. However, in the case of advanced cancer such as pancreatic cancer and bile duct cancer, due to the lack of effective treatment, the survival period of patients is usually not more than 1 year, and some patients may only survive for 3 months. Patients with advanced cancer need to build up confidence, maintain an optimistic attitude, not to give up on themselves, and actively cooperate with doctors to improve the quality of life and extend the survival period to a certain extent.
