Last week, doctors in Massachusetts announced that Senator Ted Kennedy has brain cancer. The news came after he suffered a censure seizure. Doctors found a gleams glioma, a growth in the supportive tissue of the brain. The golial glial tissue is where the largest percentage of brain tumors begin. More than forty percent of growths in the brain are gliomas. But they make up almost eighty percent of cancerous growths, like the mo malignant glioma that Senator Kennedy has. seizures and headaches are common first signs of a glioma. 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. The location of the glioma must also be considered when deciding treatment. Senator Kennedy's tumor is the left paly 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 
上周，医生在马萨储塞州宣布议员特德.肯尼迪患上脑癌．这则消息是在他病发后才传出的．医生发现在他脑部主控神经部位发现一个神经胶质瘤．神经胶质组织是大部分脑瘤的起源部分．40％以上的脑部增生都是神经胶质瘤，而且几乎80％可以导致癌变．比如肯尼迪所患的这种恶性胶质瘤．疾病发作和头痛是这神经胶质瘤的早期症状． 癌变的胶质瘤一般就像植物的根的生长一样在脑部扩散生长．这使得移除这个瘤变得更加困难．区分清除癌组织与健康组织的边界很有难度．
采取冶疗时胶质瘤的确切位置也是必须要考虑到的．肯尼迪议员的瘤位于脑部的圆形突出部位．这个部有一些感官神经包括理解力与空间认知力．也就是语言读与看的能力．从这个部位移除胶质瘤可能导致语言问题及其他部位的瘫患．
参考译文
肯尼迪所患的脑癌难以治疗
上周，马萨诸塞州的医生宣布参议员特德•肯尼迪患有脑癌。该消息在他发病后传出。医生发现他患有胶质细胞瘤，这种肿瘤生长在脑部支持组织中。胶质组织是绝大多数脑部肿瘤的起源。
超过40%的脑部增生是胶质细胞瘤。但是，约80%的癌样生长是由它们引起的，正如发生在参议员肯尼迪所患的恶性胶质细胞瘤。疾病发作和头疼是胶质细胞瘤最常见的首发症状。
恶性胶质瘤通常会像从植物伸展出来的根须一样在脑内扩散。这使切除肿瘤变的非常困难。难以找到肿瘤组织与健康组织之间清晰的界限。
在决定治疗措施时，还应该考虑胶质细胞瘤的位置。参议员肯尼迪的肿瘤位于脑部左顶叶。该部分有一些理解和空间识别的感受器，还与语言、阅读和视觉有关。移除该区的胶质细胞瘤可能引起言语问题和其他残疾。
