| In 1998, it was expected that about 110,000 people would be diagnosed with a brain tumor. Most of the tumors (about 85 percent) were expected to be benign. However, about 17,500 of the tumors were projected to be primary and malignant (cancerous). This means the tumor originates in the brain and does not stop growing. Eventually, the tumor interferes with the brain's ability to control vital functions, such as blood pressure, heart rate and breathing. In many cases, malignant brain tumors can be slowed through surgery. For more information, visit American Brain Tumor Association or National Brain Tumor Foundation. |
