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%.
For low-grade tumors, the prognosis is somewhat more optimistic. Patients diagnosed with a low-grade glioma are 17 times as likely to die as matched patients in the general population. [82] The age-standardized 10-year relative survival rate was 47% according to research in 2014. [82]
Histopathology of a brainstem glioma. A brainstem glioma is a cancerous glioma tumor in the brainstem. Around 75% are diagnosed in children and young adults under the age of twenty, but have been known to affect older adults as well. [1] Brainstem gliomas start in the brain or spinal cord tissue and typically spread throughout the nervous ...

The WHO grade has four categories of tumors: Grade 1 tumors are slow-growing, nonmalignant, and associated with long-term survival. Grade 2 tumors are relatively slow-growing but sometimes recur as higher grade tumors. They can be nonmalignant or malignant. Grade 3 tumors are malignant and often recur as higher grade tumors.
In the United States during 2013–2017, the age-adjusted mortality rate for all types of cancer was 189.5/100,000 for males, and 135.7/100,000 for females. [1] Below is an incomplete list of age-adjusted mortality rates for different types of cancer in the United States from the Surveillance, Epidemiology, and End Results program.
The most common length of survival following diagnosis is 10 to 13 months (although recent research points to a median survival rate of 15 months), [98] [99] [8] with fewer than 1–3% of people surviving longer than five years. [2] [5] [100] In the United States between 2012 and 2016 five-year survival was 6.8%. [5]
