Spinal tumors account for about 6-10% of all bone tumors in the body. Overall, they can be divided into two categories: one is primary tumors of the spine; the other is metastatic tumors of the spine, such as lung cancer and breast cancer that have metastasized to the spine. Tumors that occur in the spine are also classified as benign or malignant. Whether the disease can be cured or not is closely related to the benignity and malignancy of the tumor. For benign tumors of the spine, 70%-80% of patients can have their tumors removed through surgery, and the earlier they are detected, the greater the chance of cure. As for malignant tumors of the spine, survival time is related to the malignancy of the tumor. And if the tumor has metastasized to the spine and a spinal metastasis appears, is there still a need for treatment at that point? With the development of medical technology, it is very common for patients with thyroid cancer and breast cancer, when the tumor has metastasized to the spine, to live another 10 years if the primary tumor and the spinal tumor are treated aggressively. The more common primary tumors of the spine are: osteoid osteoma, osteochondroma, hemangioma, and multiple myeloma. Of these, the first three are benign spinal tumors and the last one is a malignant spinal tumor. With primary spinal tumors, the location of occurrence is related to the age of the patient as well as the nature of the tumor. For example, benign spinal tumors tend to appear in the posterior aspect of the spine, while malignant spinal tumors tend to destroy the vertebral body. In addition, chordomas are basically found at both ends of the spine, most likely between the first and second cervical vertebrae or on the sacrum, and less commonly on the thoracic or lumbar vertebrae. Most people think of tumors when they think of vascular “tumors”. In fact, hemangioma is not a real tumor, but rather a vascular malformation that is simply called a “tumor”. Hemangiomas are generally tumors in the true sense of the word “tumor”, such as endothelioma, hemangioepithelioma, and hemangiosarcoma. As for spinal hemangioma, it is a common vascular malformation that accounts for about 2-3% of primary tumors of the spine. It is noteworthy that 10-11% of normal people have spinal hemangioma, which means that about 100-200 million Chinese people in China have spinal hemangioma, only that most of them do not have any symptoms and therefore are unaware of it. For spinal hemangiomas, 97% of the population does not require any treatment and only about 3% of spinal hemangiomas require treatment.
