The National Cancer Institute estimated 22,070 new cases of primary brain cancer and 12,920 deaths due to the illness in the United States 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 ...

The 5-year survival rate for glioblastoma is only 6.8%. [10] Meningiomas, which develop in the meninges, are common brain tumors, representing approximately 37% of all brain tumors. [16] The incidence rate for meningiomas is 9.51 per 100,000 people. [10] Unlike gliomas, more than 98% of meningiomas are benign. [16]
It is the most common cancer that begins within the brain and the second-most common brain tumor, after meningioma, which is benign in most cases. [6] [15] About 3 in 100,000 people develop the disease per year. [3] The average age at diagnosis is 64, and the disease occurs more commonly in males than females. [2] [3]
In adult patients, the overall two-year survival rate is 19.7%, with low grade tumors holding a two-year survival rate of 31.0% and high-grade tumors holding a two-year survival rate of 16.5%. [2] In pedtiatric patients, low-grade astrocytomas held a five-year survival rate of 40% while high-grade astrocyte tumors held a five-year survival rate ...
The age-standardized 5-year relative survival rate is 23.6%. [9] Patients with this tumor are 46 times more likely to die than matched members of the general population. [9] It is important to note that prognosis across age groups is different especially during the first three years post-diagnosis.
