To prepare for Pete's appointment at Duke, I started reading up on meningiomas.

为了皮特到杜克大学医学中心就诊做准备，我开始阅读的相关资料。

They studied 1,433 Americans who have had meningiomas and compared them with 1,350 others who have not.

他研究了1433美国的患者，并把他1350非患者进行对比。

We're much more likely to develop a brain tumor, like a meningioma.

我更有可能患上肿，例如。

A few days later, a biopsy revealed that the tumor was a rare aggressive type of meningioma that exhibits cancerlike behavior.

几天后，活组织检查显示，皮特的肿是一种罕见的侵袭性，表现出癌症样行为。

In tumors called meningiomas, recurrence is found to be equal, or lower, when the patient undergoes radiosurgery.

在称为的肿中，当患者接受放射外科手术时， 发现复发率相同或更低。

In rich countries, five men in every 200,000, and twice as many women, develop tumours called meningiomas that affect the membranes surrounding the brain.

在富裕的国家里，每200,000人中就有5男性-女性数量的两倍-得一种叫的肿，此影响大周边的。

The researchers found that people who had had a meningioma were more than twice as likely as those who had not to have had at least one bitewing X-ray.

研究发现患脊的病人发病的可能性是那些没拍过咬翼片的人的两倍以上。

Even more troubling was the finding that people who had been given a panorex when they were under ten had 4.9 times the normal risk of developing a meningioma.

更让人担忧的发现是十岁以下拍过全颌X光的人患的概率是正常风险值的4.9倍。

Ironically, because past research studying the after-effects of exposure to things like atom bombs and radiation treatments for cancer suggests the most important environmental risk factor for meningiomas is ionising radiation.

讽刺的是，对人体暴露于类似原子弹辐射和癌症放射疗法后续影响的研究显示，产生的最主要的环境风险因素是离子辐射。
