Nervous tissue consists of two general types of cells: nerve cells and glial cells. Glial cells are mitotic, whereas neural cells are not (excluding the small population of stem cells). Which type of cell is most likely to be involved in brain cancer, and why?
What will be an ideal response?
Cancer results from uncontrolled cell division in mitotic cells. Therefore, glial cell cancers (gliomas) are the most common type of nervous system cancers, as they have the most mitotic activity.
