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，我被诊断为恶形细瘤。

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

脑肿瘤通常以异细的类命名，比如，形细瘤由异的形胶质细形成。

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

尽管形细瘤可分为I到IV级，青少年毛细形细瘤只有I级，因为它们通常为良且生长缓慢。

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.

因为形细遍布大脑和脊髓，形细瘤也可以遍布在这些部位，但青少年毛细形细瘤大多数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.

尽管髓母细瘤可能最常见的恶肿瘤，最常见的儿童原发脑肿瘤一种形细瘤，称为青少年毛细形细瘤。

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形细瘤（SEGA）的风险也会增加；SEGA一种可由室管膜下结节引起的癌症。
