Then, two weeks later, after surgery, the pathology reports came back and I was diagnosed with an anaplastic astrocytoma.

然后，在手术两周后，病理报告出来了，断间变性恶性细胞瘤。

They are typically named by the cell type involved, so for example an astrocytoma is a tumor formed by mutated astrocytes.

脑肿瘤通常以变异细胞的类型命名，比如，细胞瘤是由变异的胶质细胞成。

And while astrocytomas can be graded I through IV, juvenile pilocytic astrocytomas are only grade I because they are generally benign and slow-growing.

尽管细胞瘤可分I到IV级，青少年毛细胞型细胞瘤只有I级，是它们通常良性且生长缓慢。

Because astrocytes are found through the brain and spinal cord, astrocytomas can form throughout those locations, but juvenile pilocytic astrocytomas are mostly infratentorial tumors in the cerebellum or near the brainstem.

细胞遍布大脑和脊髓，细胞瘤也可以遍布在这些部位，但青少年毛细胞细胞瘤大多数是位于小脑内或脑干旁的脑幕下肿瘤。

Now, while medulloblastoma may be the most common malignant tumor, the most common primary pediatric tumor is a type of astrocytoma called a juvenile pilocytic astrocytoma.

尽管髓母细胞瘤可能是最常见的恶性肿瘤，最常见的儿童原发脑肿瘤是一种细胞瘤，称青少年毛细胞型细胞瘤。

It was something called an anaplastic astrocytoma and while the surgery had been successful and the tumor was gone, the microscopic cancerous cells it left behind remained, impossible to remove.

这是一种叫做间变性细胞瘤的东西，虽然手术很成功，肿瘤消失了，但它留下的微小癌细胞仍然存在，无法去除。

Individuals are also at an increased risk of developing a subependymal giant cell astrocytoma, or SEGA, which is a type of cancer that can arise from the subependymal nodules.

个体发生室管膜下巨细胞细胞瘤（SEGA）的风险也会增加；SEGA是一种可由室管膜下结节引起的癌症。
