孩子的急性白血病症狀是什麼

The signs and symptoms of acute leukemia in children depends on how much of the child’s healthy bone marrow cells have been taken over by leukemia cells, as well as whether or not the leukemia cells have clustered together in other organs—also called extramedullary spread.
兒童急性白血病的症狀和體徵取決於白血細胞取代多少骨髓細胞，以及白血細胞是否在其他器官裏面會產生堆積，也稱爲髓外蔓延。

Most children will display signs (listed below) that the leukemia cells in their marrow are interfering with the production of healthy red blood cells, white blood cells, and platelets.
大多數孩子都將顯示一些跡象(下面列出)，在骨髓裏面的白血病細胞正干擾健康的紅細胞、白細胞和血小板的產生。

Don't forget that many of these symptoms are also signs of more benign conditions.
別忘了，這些症狀很多都是以更良性的跡象開始。

1) Anemia (low red blood cells)
1）貧血（低的紅細胞）

When the leukemia cells in the child’s marrow crowd out the production of red blood cells, this may lead to a condition called anemia. In anemia, there are too few red blood cells available to carry oxygen around to the tissues of the body. If your child is anemic, they may be more tired or weaker than usual, look pale, or become short of breath easily.
當孩子骨髓裏的白血細胞排斥紅細胞的產生時，這可能會導致貧血的狀況。在貧血症狀中，紅細胞運輸到身體其他組織時攜帶的氧氣太少。如果你的孩子是貧血,他們可能會比平常更累或更弱、臉色蒼白或者容易產生呼吸急促。

2) Thrombocytopenia (low platelets)
2）血小板減少（低的血小板）

If the bone marrow becomes too overcrowded by leukemia cells to produce normal numbers of platelets, a condition called thrombocytopenia occurs. In thrombocytopenia, too few platelets are available to help the blood form clots. Your child may bruise or bleed very easily.
如果骨髓裏的白血細胞太多，會對正常血小板數量的產生有影響，那麼這種狀況稱爲血小板減少症。血小板減少症、血小板太少不利於血液形成凝塊，你的孩子可能很容易擦傷或流血。

3) Frequent Infections
3）頻繁感染

The white blood cells that are over-produced in leukemia are abnormal and to not fight infection.
在白血病中，白細胞的過多產生是不正常的，而且不能對抗感染。

You may notice your child has been getting a lot of fevers and infections that they can’t seem to fight off.
你可能會注意到你的孩子得了發燒和感染時，他們似乎無法抵抗。

4) Bone or Joint Pain
4）骨頭或關節疼痛

As the marrow in the center of the child’s bones becomes crowded and full of leukemia cells, they may complain of pain in their bones or joints, or you may notice they are limping or walking abnormally.
隨着孩子骨骼中心的骨髓變得擁堵和白血病細胞的充斥，他們會感到骨頭或關節疼痛，或者你可能會注意到他們正一瘸一拐的行走。
