病因病理
-
骨转移是由什么原因引起的？
通常发生在各种癌症当中。较公认的转移方式为:
①原发肿瘤细胞浸润周围组织进入脉管系统(血液和淋巴) ;
②肿瘤细胞脱落释放于血循环内;
③肿瘤细胞在骨髓内的血管壁停留;
④肿瘤细胞再透过内皮细胞逸出血管, 继而增殖于血管外;
⑤转移癌病灶内血运建立, 形成骨转移病灶。

骨转移应该如何诊断？
癌症患者当出现骨痛症状时则可能发生了癌症的骨转移。
鉴别
-
骨转移容易与哪些症状混淆？
骨转移症状与肿瘤转移的部位、数量有关。1、癌骨转移早期一般无任何症状，骨同位素扫描可发现有病变的骨骼。2、肋骨转移引起的胸痛，多表现为胸壁部位局限的、有明确压痛点的疼痛。3、脊髓转移引起后背部正中或病变部位疼痛，而四肢或躯干的骨转移引起该部位的局限性疼痛。

骨转移应该如何预防？
骨转移并非威胁癌症病员生命的直接原因，但如肿瘤转移到机体承重骨如颈椎、胸椎、腰椎等部位则可造成瘫痪的严重后果。因此对癌出现骨转移患者应及时治疗。
