Non-cancerous Brain Tumors Linked to Frequent Dental X-rays
People who received frequent dental X-rays in the past, before dosages were lowered, have an increased risk of developing a meningioma, the most common and potentially debilitating type of non-cancerous brain tumor, a new study led by the Yale School of Public Health has found. The study is published online in Cancer, a journal of the American Cancer Society.
Meningioma is listed as a rare disease by the National Institutes of Health. The estimated incidence is up to 8 out of 100,000 people, and it occurs more frequently among women than men. Although it is the most frequently diagnosed type of brain tumor, meningioma is listed as a rare disease by the National Institutes of Health. Tumors develop in a membrane that envelops the brain and the central nervous system known as the meninges. They can grow undetected for years and eventually reach the size of a baseball or larger. While they are not cancerous, they can cause debilitating side effects such as headaches, vision problems, and loss of speech and motor control. (more…)
