Modeled trend lines were calculated from the underlying rates using the Joinpoint Trend Analysis Software.
New cases are also referred to as incident cases in other publications. Rates of new cases are also referred to as incidence rates.
Rate of New Cases and Deaths per 100,000: The rate of new cases of brain and other nervous system cancer was 6.4 per 100,000 men and women per year. The death rate was 4.4 per 100,000 men and women per year. These rates are age-adjusted and based on 2014–2018 cases and deaths.
Lifetime Risk of Developing Cancer: Approximately 0.6 percent of men and women will be diagnosed with brain and other nervous system cancer at some point during their lifetime, based on 2016–2018 data.
Prevalence of This Cancer: In 2018, there were an estimated 173,438 people living with brain and other nervous system cancer in the United States.
How Many People Survive 5 Years Or More after Being Diagnosed with Brain and Other Nervous System Cancer?
Relative survival is an estimate of the percentage of patients who would be expected to survive the effects of their cancer. It excludes the risk of dying from other causes. Because survival statistics are based on large groups of people, they cannot be used to predict exactly what will happen to an individual patient. No two patients are entirely alike, and treatment and responses to treatment can vary greatly.
Based on data from SEER 18 2011–2017. Gray figures represent those who have died from brain and other nervous system cancer. Green figures represent those who have survived 5 years or more.
Survival by Stage
Cancer stage at diagnosis, which refers to extent of a cancer in the body, determines treatment options and has a strong influence on the length of survival. In general, if the cancer is found only in the part of the body where it started it is localized (sometimes referred to as stage 1). If it has spread to a different part of the body, the stage is regional or distant. For brain and other nervous system cancer, 76.7% are diagnosed at the local stage. The 5-year relative survival for localized brain and other nervous system cancer is 35.3%.

How Common Is This Cancer?
Compared to other cancers, brain and other nervous system cancer is relatively rare.
|Rank||Common Types of Cancer||Estimated New
|1.||Breast Cancer (Female)||281,550||43,600|
|3.||Lung and Bronchus Cancer||235,760||131,880|

|16.||Brain and Other Nervous System Cancer||24,530||18,600|
Brain and other nervous system cancer represents 1.3% of all new cancer cases in the U.S.
In 2021, it is estimated that there will be 24,530 new cases of brain and other nervous system cancer and an estimated 18,600 people will die of this disease.
Who Gets This Cancer?
This cancer is slightly more common in men than women and among those with certain genetic syndromes. The rate of new cases of brain and other nervous system cancer was 6.4 per 100,000 men and women per year based on 2014–2018 cases, age-adjusted.

Trends in Rates
Changes Over Time
Keeping track of new cases, deaths, and survival over time (trends) can help scientists understand whether progress is being made and where additional research is needed to address challenges, such as improving screening or finding better treatments.
Using statistical models for analysis, age-adjusted rates for new brain and other nervous system cancer cases have been falling on average 0.2% each year over 2009–2018. Age-adjusted death rates have been rising on average 0.5% each year over 2009–2018. 5-year relative survival trends are shown below.

More About This Cancer
Cancer and the Brain

There are many types of brain and spinal cord tumors. Together, the brain and spinal cord make up the central nervous system (CNS).
The tumors may be either benign (not cancer) or malignant (cancer). Tumors that start in the brain are called primary brain tumors.
Primary brain tumors may spread to other parts of the brain or to the spine, but they rarely spread to other parts of the body. Often, tumors found in the brain have started somewhere else in the body and spread to one or more parts of the brain. These are called metastatic brain tumors (or brain metastases). Metastatic brain tumors are more common than primary brain tumors.

These stat facts focus on population statistics that are based on the U.S. population. Because these statistics are based on large groups of people, they cannot be used to predict exactly what will happen to an individual patient. To see tailored statistics, browse SEER*Explorer. To see statistics for a specific state, go to the State Cancer Profiles.
The statistics presented in these stat facts are based on the most recent data available, most of which can be found in SEER*Explorer. In some cases, different year spans may be used.
Estimates of new cases and deaths for 2021 are projections made by the American Cancer Society (ACS), based on earlier reported data.
Cancer is a complex topic. There is a wide range of information available. These stat facts do not address causes, symptoms, diagnosis, treatment, follow-up care, or decision making, although links are provided to information in many of these areas.
