Glioblastoma
The most common length of survival following diagnosis is 12 to 15 months, with fewer than 3% to 5% of people surviving longer than five years. Without treatment survival is typically 3 months.
List of people with brain tumors
The National Cancer Institute estimated 22,070 new cases of primary brain cancer and 12,920 deaths due to the illness in the United State in 2009. The age-adjusted incidence rate is 6.4 per 100,000 per year, and the death rate is 4.3 per 100,000 per year. The lifetime risk of developing brain cancer for someone born today is 0.60%. Only around a third of those diagnosed with brain cancer survive for five years after diagnosis. These high overall mortality rates are a result of the prevalence of aggressive types, such as glioblastoma multiforme. Nearly 14% of new brain tumor diagnoses occur in persons under 20 years of age.
