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 occur more often in older adults and more often in men.
Glioblastoma symptoms include headaches that keep getting worse; nausea and vomiting; blurred or double vision; and seizures. There’s no cure for glioblastoma, which is also known as glioblastoma multiforme. Treatments might slow cancer growth and reduce symptoms.
