The survival period of patients with spreading cancer cells is generally short, most of them are around 6 months, but the situation varies from person to person and cannot be generalized, if the disease is better controlled, the survival period can be extended. When cancer cells have spread, it means that the tumor is already in advanced stage, and the survival period is generally shorter at that time. In general, if the tumor is more malignant, the survival period may only be 2-3 weeks, while if the tumor is less malignant, the survival period may be 6-10 months. The specific survival time varies from person to person and from disease to disease. The patient’s physical quality, treatment conditions, patient’s mentality and family social environment all have a certain influence on the survival period. After the spread of cancer cells, patients are advised to take medication according to medical advice to reduce pain, improve life quality, actively cooperate with treatment, and not to give up on themselves.
