Brain Tumor Facts

Today, an estimated 700,000 people in the United States are living with a primary brain tumor, and approximately 88,970 more will be diagnosed in 2022. Brain tumors can be deadly, significantly impact quality of life, and change everything for a patient and their loved ones. They do not discriminate, inflicting men, women, and children of all races and ethnicities.

  • Overall, Black / African American people have slightly higher incidence rates of primary brain and other CNS tumors compared to other races at 24.58 per 100,000 persons in the U.S., followed by:
    • White – 24.24/100,000

  • Tumors of the pituitary and CNS lymphoma are the only tumor types that were higher in Hispanic / Latino/a / Latinx than in those who are not Hispanic / Latino/a / Latinx

*The U.S. Census Bureau defines race as a person’s self-identification with one or more social groups, which can include white, Black or African American, Asian, American Indian, Alaska Native, Native Hawaiian, and/or Other Pacific Islander. Federal statistical standards used by the Census and the National Center for Education Statistics, conceptualize a person’s ethnicity into one of two categories: Hispanic (or Latino/a/x) or Not Hispanic (Latino/a/x). A Hispanic (or Latino/a/x) person can self-report as any race.

**While there are several tumor types where significant differences in incidence were observed by race and/or ethnicity, in most cases the actual difference in incidence rates is small and may not be significant. 

  • Overall, incidence rates for all primary brain and CNS tumors are higher in females (58% of diagnoses) than in males (42%)
  • Non-malignant brain tumors occur significantly more often in females (64%) than in males (36%)
  • Malignant brain tumors occur slightly more often in males (56%) than in females (44%)
  • Incidence rates for specific brain tumor types vary. For example, glioblastoma diagnoses are more common in males, while meningioma diagnoses are more common in females
  • Overall, males have higher mortality rates from malignant brain tumors than females, with the exception of glioblastoma, embryonal tumors, and germ cell tumors

  • Unlike other types of cancer, primary brain and other CNS tumors are not staged, but are classified according to the WHO Classification of Tumors of the Central Nervous System, which assigns a “grade” of 1-4, based on how aggressive the tumor is predicted to behave, clinically
    • Grade 1 tumors are typically non-malignant and the lowest, or least aggressive, grade. While grade 4 tumors, primarily glioblastoma, are the highest and most aggressive grade of tumors
  • More than any other cancer, brain tumors can have lasting and life-altering physical, cognitive, and psychological impacts on a patient’s life
  • Malignant brain tumors cause an average of 20 Years of Potential Life Lost (YPLL) for individuals diagnosed as adults, which exceeds most common cancers. Among children ages 0-19 years, brain tumors represent the largest cause of YPLL due to cancer, with a mean YPLL of approximately 80 years [1]
  • The incidence rates for brain tumors are highest among individuals ages 85+, and lowest among children and adolescents ages 0-19 years
  • Despite the number of brain tumors, and their devastating prognosis, there are only five FDA approved drugs – and one device – to treat brain tumors
    • For many tumor types, surgery and radiation remain the standard of care
  • There has never been a drug developed and approved specifically for malignant pediatric brain tumors
  • The five approved drugs for brain tumors have provided only incremental improvements to patient survival, and mortality rates remain little changed over the past 30 years
  • Each year, approximately 70,000-170,000 cancer patients are diagnosed with brain metastases (metastatic brain tumors/secondary brain tumors), while ~100,000 will die every year as the result of brain metastases
    • The incidence of brain metastases appears to be increasing [2]
    • Several studies have cited that the percentage of cancer patients who will develop brain metastases is anywhere from 6-28%
    • Approximately 80% of cancers have been associated with the ability to metastasize to the brain
      • These include melanoma (where nearly 50% of cases will metastasize to the brain), lung, breast, renal, and colorectal cancers
  • Brain tumors represent the highest per-patient initial cost of care for any cancer group, with an annualized mean net cost of care approaching $150,000; and the highest annualized mean net costs for last-year-of-life care, relative to other cancers, at $135,000 to $210,000 (depending on age and sex) per patient [3]

Notes

  • Unless otherwise notes, all statistical figures have been sourced from the Central Brain Tumor Registry of the United States (CBTRUS) in CBTRUS Statistical Report: Primary Brain and Other Central Nervous System Tumors Diagnosed in the United States in 2013–2017, Oct. 2020 (www.cbtrus.org).
  • Brain tumor statistics are typically classified as “brain and other central nervous system (CNS) tumors” in research reports. For ease and clarity, in this document we use “brain tumors” as shorthand to include both tumors occurring in the brain and other central nervous system locations. 
  • Unless otherwise noted, all references on this page refer to primary brain tumors, and all stats refer to U.S. populations.
