The symptoms of glioblastoma are often similar to the symptoms of other types of brain tumors, such as neuromas and meningiomas. Chronic, unexplained headaches are especially common, as are neurological complications such as seizures and double vision.

Other glioblastoma symptoms include:

  • Vomiting
  • Changes in temperament or personality
  • Difficulty speaking or responding to other peoples’ speech
  • Difficulty swallowing
  • Short-term memory loss
  • Fainting
  • Loss of appetite
  • Muscle weakness in the arms or legs

The specific symptoms that a person develops depends on where in the brain the tumor has developed, as well as how large it is and how quickly it is growing. Some people experience few, if any, symptoms, while other people experience more frequent and wide-ranging complications.

Compared to other, slower-growing types of brain cancer, glioblastoma often produces symptoms relatively quickly. Glioblastomas can spread quickly to the healthy surrounding tissues, which makes them less likely to go undetected for an extended period of time.

How is glioblastoma diagnosed?

If you’re experiencing any unusual neurological symptoms, it’s a good idea to make an appointment with a physician. These symptoms are often caused by more common, less serious conditions, but if cancer is present, early detection is incredibly important. Survival outcomes and a patient’s quality of life are often most favorable for glioblastomas that are diagnosed and treated early. An experienced neuro-oncologist can perform any necessary neurological tests and imaging scans to help you determine the cause of your symptoms.

The Neuro-Oncology Program at Moffitt Cancer Center welcomes patients who are experiencing symptoms of glioblastoma, as well as patients who have already received a diagnosis and are looking for a second opinion or an individualized treatment plan. Referrals are not required. To request an appointment, call 1-888-663-3488 or submit a new patient registration form online.
