Brain Cancer Like Kennedy's Is Difficult to Treat(1/2)

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 begin. More than forty percent of growths in the brain are gliomas. But they make up almost eighty percent of cancerous growths, like the 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 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.

上周马萨诸塞州的医生宣布参议员TK患有脑癌。该消息在他发病后传出。医生发现了一种神经胶质瘤，其生长在大脑支持组织的内部。这种神经胶质组织绝大多数是大脑肿瘤的起源。超过了40%的脑部增长是胶质细胞瘤，但是它们组成了80%的癌细胞的生长。就像是参议员肯尼迪有的恶性胶质细胞瘤。病发和头疼是它的普遍第一症状。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。
