Last week, doctors in Massachusetts announced that Senator Ted Kennedy has brain cancer. The news came after he suffered a seizure. Doctors found a glioma, a growth in the supportive tissue of the brain. The glial tissue is where the largest percentage of brain tumors began.

 上周，马萨诸塞州的医生宣布参议员Ted Kennedy患有脑癌。这个新闻在他发病后被公布。医生在他的大脑支持性组织中发现了神经胶质瘤。神经胶质组织是大脑肿瘤出现频率最高的区域。

More than 40% of growths in the brain are gliomas. But they make up almost 80% of cancerous growths, like the malignant glioma that Senator Kennedy has. Seizures and headaches are common first signs of a glioma.

 超过40%的脑部增生是神经胶质瘤，但是约80%的癌样生长是由它们引起的。就像参议员Kenedy的恶性神经胶质瘤。它的普发第一症状是病发和头疼。

Cancerous glial tumors generally spread in the brain the way roots spread from a plant. That makes removing the tumor more difficult. A clear border between the cancer and healthy tissue can be difficult to find.

 癌样神经胶质瘤通常在脑部以植物伸展根须的方式扩散。这使得移除肿瘤更加困难。癌症组织和健康组织之间的清晰界限可能会难以分辨。

The location of the glioma must also be considered when deciding treatment. Senator Kennedy’s tumor is in the left parietal lobe of the brain. This area is involved in some sensory understanding and spatial recognition, as well as language, reading and vision. Removal of a glioma from this area can result in speech problems and other disabilities.

 决定手术前必须确定肿瘤的所在部位，参议员Kenedy的肿瘤位于脑部左顶叶，这个部位包括了许多感官与空间控制神经，例如语言，阅读和视觉。从这个部位移除肿瘤又可能导致语言问题和其他残疾。
