早期症状常常悄无声息,缺乏特异性,极易被误认为是普通感冒、疲劳或营养不良。最初,你可能只是感觉比平时更累,休息也无法缓解,或者脸色、口唇日渐苍白,偶尔有点低烧、牙龈容易出血。这些信号微弱,却可能是骨髓正常造血开始受抑制的征兆。

随着白血病细胞全面占领骨髓并向全身扩散,症状会如潮水涌来,形成一个清晰而残酷的链条:

1 正常血细胞枯竭的后果(髓内浸润):
红细胞减少导致贫血由于红细胞携带氧气,这会导致虚弱、疲倦和疲劳等症状。患者会出现呼吸急促、头晕乏力,动则心慌气短。而且由于红细胞赋予血液红色,患者会看起来面白如纸。
血小板减少导致凝血障碍,身体失去修补能力,皮肤出现广泛瘀斑,轻轻一碰就青紫一片,鼻血、牙龈出血不止;甚至可能出现内脏出血或危险的颅内出血。
正常白细胞减少导致免疫崩溃,身体失去防御屏障,反复出现难以控制的感染、高烧不退,普通肺炎也可能致命。

2 白血病细胞全身侵袭的后果(髓外浸润):
淋巴结、脾脏肿大异常,细胞在这些免疫器官安营扎寨,导致颈部、腋下出现无痛肿块,肚子因肝脾肿大而隆起、发胀。
骨骼关节疼痛:细胞在骨髓腔内过度增生,产生压力,引起骨骼、关节的锐痛。
进犯中枢神经系统:可能出现头痛、呕吐、视力模糊甚至抽搐。
皮肤浸润:身上可能出现不痛不痒的青色或紫色结节。

从最初的无名疲惫,到高烧感染与出血倾向交织再到全身器官的全面警报,白血病的演进,是一场身体从内部被逐渐“掏空”和“侵占”的悲剧。
