Cancers of the brain are the consequence of abnormal growths of cells in the brain. Brain cancers can arise from primary brain cells, the cells that form other brain components (for example, membranes, blood vessels), or from the growth of cancer cells that develop in other organs and that have spread to the brain by the bloodstream (metastatic brain cancer). This Brain Cancer Medical PowerPoint Theme or template is dominantly colored Grey. The download includes a Title slide that's visually coordinated with the remaining slides in the template.
