Glioblastoma Awareness Day will be observed on Wednesday, July 21, which makes this a good time to learn more about one of the most complex, deadly and treatment-resistant cancers.

Glioblastoma, a type of glioma, is an aggressive cancer that can occur in the brain or spinal cord. It can occur at any age, but it tends to occur more often in older adults.

Approximately 13,000 people in the U.S. will be diagnosed with glioblastoma in 2021, according to the National Brain Tumor Society. The five-year survival rate is 7.2%, and the median length of survival is eight months.

Treatments may slow progression of the cancer, and reduce signs and symptoms. But glioblastoma can be difficult to treat, and a cure often is not possible.

Learn more about the diagnosis and treatment options for glioblastoma.

Connect with others talking about living with glioblastoma or caring for someone with glioblastoma in the Brain Tumor support group on Mayo Clinic Connect, an online patient community moderated by Mayo Clinic.
