So what exactly is a diffuse low-grade glioma, MAPK pathway–altered? Let's break that mouthful down one piece at a time.

First: glioma. Your brain is made up of many different kinds of cells. One of the most important types are called glial cells. These aren't the cells that do the thinking — those are called neurons. Glial cells are more like the support staff of the brain. They hold things together, provide nutrients to the neurons, clean up waste, and help keep the whole system running smoothly. A glioma is a tumor that starts in these glial cells. It's the most common type of brain tumor in adults, which sounds strange to hear at first, but it means doctors have a lot of experience dealing with them.

Next: low-grade.
