These symptoms result because the glioblastoma cancer grows very fast and causes increased pressure in the brain, as the American Brain Tumor Association explains. The tumors can occur in the frontal and temporal lobes as well as in the cerebellum and brain stem, according to the University of Texas MD Anderson Cancer Center, and the tumor's location influences the symptoms that the patient experiences.

The two types of glioblastomas are primary glioblastomas and secondary glioblastomas, according to WebMD. Primary glioblastomas are the most common type of glioblastomas.

Primary glioblastomas are very aggressive, and the symptoms appear quickly, according to the American Brain Tumor Association. Secondary glioblastomas have a longer and slower growth history. They progress slowly, but they are still very aggressive. They may start as low-grade tumors and eventually develop into a higher grade. Secondary glioblastomas represent about 10 percent of glioblastomas and mostly affect people who are 45 years old or younger.
