脊柱转移瘤是其它部位的癌细胞通过血流或淋巴系统转移并定植到脊椎骨的骨髓，形成肿瘤。来源于其它器官，比如肺、乳腺、肝脏的肿瘤，也可直接长入甚至穿透脊柱。 警告：请在有WIFI的场所观看视频，土豪请随意。 Metastatic spine cancer is a condition where cancerous cells that developed elsewhere in the body travel through the bloodstream or the body's lymphatic system and settle into the bone marrow of the vertebrae, forming tumors. 脊柱转移瘤是其它部位的癌细胞通过血流或淋巴系统转移并定植到脊椎骨的骨髓，形成肿瘤。 Cancerous tumors based in other organs, such as the lungs, breast, and liver, can also grow into and even through the spine. 来源于其它器官，比如肺、乳腺、肝脏的肿瘤，也可直接长入甚至穿透脊柱。 Most metastatic spine cancer occurs in the thoracic region of the spine, but it can also develop in the lumbar and cervical regions. 大部分脊柱转移瘤发生于脊柱的胸段，但也可侵犯腰椎和颈椎。 Metastatic spine cancer almost always involves just the bone, though rarely it can involve the soft tissue of the spine. 脊柱转移瘤往往只侵犯骨组织，侵犯脊柱软组织的较少。 Often, metastatic spine tumors involve more than one vertebra of the spine. 脊柱转移瘤往往侵犯不止一个椎体。 Tumors growing within the vertebrae can make the spinal bones weak, causing them to break and collapse, a condition called a compression fracture. This type of fracture usually causes sudden back pain, as well as pain that is sensitive to touch over the site of the fracture. 肿瘤在脊柱骨内生长会使脊柱骨强度下降，导致破裂塌陷，这种情况称为压缩性骨折。这种类型的骨折通常导致背部突然疼痛，同时骨折部位会有明显的触痛。 These fractures, as well as the tumors themselves, can compress nerves in and around the spine, causing pain, numbness, tingling and muscle weakness that can radiate through the arms or legs, called a radiculopathy. 骨折和肿瘤本身一样，会压迫脊柱内和周围的神经，引起疼痛、麻木、针刺感和肌无力，放射到胳膊或腿，称为神经根病变。 Depending on the location and size of the tumor, other neurological symptoms can include loss of bowel or bladder control and paralysis in the portion of the body below the tumor. 根据肿瘤的部位和大小，其它神经症状包括大小便失禁以及肿瘤部位以下的身体瘫痪。 Anyone with active cancer or a history of cancer should see a medical professional about any sudden onset of back pain or related neurological symptoms. 每个恶性肿瘤活跃期或有既往史的病人突然出现背痛或相关神经症状时应该找医学专家就诊。 （胡佰文 译） |
