Glioblastoma is a type of cancer that starts as a growth of cells in the brain or spinal cord. It grows quickly and can invade and destroy healthy tissue. Glioblastoma forms from cells called astrocytes that support nerve cells.

Glioblastoma can happen at any age. But it tends to happen more often in older adults. Glioblastoma symptoms may include headaches that keep getting worse, nausea and vomiting, blurred or double vision, trouble speaking, altered sense of touch, and seizures. There also may be trouble with balance, coordination, and moving parts of the face or body.

There's no cure for glioblastoma. Treatments might slow cancer growth and reduce symptoms. (https://www.mayoclinic.org/diseases-conditions/glioblastoma/symptoms-causes/syc-20569077)
