The survival time of patients with malignant bone tumors depends on the pathological type, size and treatment of the tumor, and needs to be analyzed on a case-by-case basis. In the case of low-grade malignant bone tumors, such as chondrosarcoma of grade 1-2, the prognosis survival time is significantly higher than that of osteosarcoma and highly malignant tumors such as Ewing sarcoma. If patients can be detected early, the tumor size is relatively small and no distant metastasis occurs, the prognosis is relatively good and the survival time is likely to be more than 5 years. In addition, if patients receive regular and reasonable chemotherapy and surgical treatment, and the tumor has not metastasized at the time of consultation, some patients may even survive for a long time. It is suggested that patients with malignant bone tumor should maintain an optimistic attitude and receive treatment as early as possible. In daily life, they should quit smoking and alcohol, avoid spicy and fatty food, and can eat more mushrooms, seaweeds, almonds and other foods with anti-cancer effects.
