Glioblastoma is not known for spreading to other organs, but instead remains in the brain. It grows at a very rapid pace and will invade the surrounding tissue. The cancerous cells will multiply and their growth will begin to affect other parts of the brain by pressing on the adjacent structures.

Glioblastoma Symptoms

Glioblastoma causes a range of symptoms, including nausea, headaches, vision or/and speech problems, seizures and fatigue. To make an accurate diagnosis, physicians rely on the results of a CT scan, PET scan or MRI, physical exam and a tissue sample analysis or biopsy.

Glioblastoma Prognosis

Glioblastoma is an incurable form of cancer, with a survival of less than a year. The prognosis can vary among patients, depending on the patient’s functioning, tumor location and whether the tumor can be fully removed through surgery. The prognosis is still typically poor.

Once Glioblastoma is confirmed, an oncologist will formulate an individualized treatment plan, which typically includes chemotherapy, radiation and surgery. Since Glioblastoma has a tendency to invade the surrounding tissue, residual malignant cells can remain behind even after a “complete resection.” In this case, the surgery is followed up with radiation and chemotherapy in an effort to eradicate the remaining cancer cells.
