will be diagnosed with brain cancer. Brain tumors are the second leading cause of death in the age group 15-34. Brain tumors are the second fastest growing cause of cancer death among those over age 65. Approximately 44 percent of all primary brain tumors are benign. Unlike most benign tumors when located on the brain they can cause death. Because of their location brain, tumors are difficult to treat. Brain cancer research is underfunded. ? The cause of brain cancer is still unknown. The cure rate for brain cancer is lower than that of most other types of cancer.
