概述

前列腺癌 4 期这种癌症始于前列腺并扩散到附近的淋巴结或身体其他部位。

前列腺癌 4 期的诊断并不常见。大多数情况下,当癌症局限于前列腺癌时,才可以在较早阶段诊断出前列腺癌。

治疗可以减慢或缩小晚期前列腺癌,但对于大多数男性而言,前列腺癌 4 期无法治愈。但治疗仍然可以延长生命,减少癌症的体征和症状。

症状

前列腺癌 4 期的体征和症状可能包括:

  • 排尿疼痛
  • 小便无力
  • 精液带血
  • 骨痛
  • 腿部肿胀
  • 疲劳

何时就诊

如果您有任何令您担心的持续体征或症状,请与医生约诊。

病因

医生们尚不清楚前列腺癌 4 期的致病因素。

出现前列腺癌 4 期时,前列腺癌细胞已经从前列腺脱离并扩散到淋巴结或身体其他部位。

扩散到前列腺之外的前列腺癌细胞最常转移到:

  • 淋巴结
  • 骨骼
  • 肝脏

风险因素

可能增加前列腺癌 4 期发病风险的因素包括:

  • 前列腺癌家族史。若男性携带的某些遗传性基因突变会升高前列腺癌发生风险,则罹患更具侵袭性的前列腺癌的风险会升高。
  • 非裔美国人。黑人罹患侵袭性前列腺癌的风险较高。
