What Is the Prognosis for Stage 4 Brain Cancer?

As of 2014, the American Brain Tumor Association states that the prognosis for stage four brain cancer is a survival rate of approximately 14.6 months. Stage four brain cancer consists of malignant tumors called glioblastomas. The American Cancer Society states that as of 2014, the mortality rate is higher in males than females.

WebMD states that stage four brain cancer is known as glioblastoma multiforme because it is the most malignant and aggressive form of a brain tumor. These tumors grow quickly and are nourished by the body’s blood supply. Symptoms include diminished mental capacity, headaches, new seizures and difficulty with speech. Cedars-Sinai states that this type of tumor can arise at any age. As of 2014, these tumors are most often seen in adults over the age of 50, but the other risk factors remain unknown.

The American Cancer Society explains that there may be environmental factors related to the cause of this type of cancer, but as of 2014, the absolute causes remain unidentified. Diagnostic testing may include an MRI, CT scan or field vision tests. Typical treatment of a glioblastoma tumor may include surgery, radiation therapy and chemotherapy. However surgery is not often successful in removing the entire tumor, and the tumor continues to reoccur even with treatment.
