Question

Quizplus · Accepted Answer

Malignant brain tumors can release cells that travel to other body areas through the bloodstream or lymphatic system, resulting in the formation of new tumors, which can be lethal. The other options are incorrect because hydrocephalus caused by increased flow of cerebrospinal fluid, glutamate release, and glycine release killing nearby cells are not the major causes of death in patients with malignant brain tumors. Additionally, malignant brain tumors can be diagnosed using imaging techniques, and not only through autopsy.
