The survival time of patients with osteoma requires a comprehensive analysis based on the nature of the tumor, its size, growth site, and treatment modality, and requires a case-by-case analysis due to individual differences. Early stage osteoma does not have obvious clinical manifestations and is non-specific and may not be easily detected. The earlier the bone tumor is detected, the greater the possibility of cure and the longer the survival time of the patient.1. Benign bone tumor: the tumor develops slowly or does not continue to grow after reaching a certain level, usually the patient has no conscious symptoms, does not affect normal life expectancy, and does not have distant metastasis. If the tumor is small, asymptomatic and does not grow, it can be treated without any treatment and regular review can be done. If the tumor is large in size and even has deformity or compression symptoms, it is recommended to take surgical resection to avoid the possibility of malignancy, and at the same time, it can relieve the local compression symptoms and prevent complications. 2. Malignant tumor: If it is a low degree malignant bone tumor, such as chondrosarcoma, the survival time after cure will be prolonged compared with other highly malignant tumors. If the tumor can be detected early and the volume is relatively small and no distant metastasis occurs, the survival time of most people may reach 5 years. If active treatment is carried out, the prognosis is better and can even reach no difference with normal people. If the tumor grows rapidly and causes systemic symptoms or metastases through blood system or lymphatic system, the survival time of patients will be greatly reduced, and patients with metastatic bone tumor may only survive 1-2 years, but through active treatment, the quality of life can be improved and the survival time can be prolonged.
