What we aim to solve

SOURCE: Self-reported by organization

Brain tumors affect people of any race, gender, or age. Approximately 700,000 Americans are living with a primary brain tumor. More so than any other cancer, brain tumors can have life-altering psychological, cognitive, behavioral, and physical effects.

Our programs

SOURCE: Self-reported by organization

What are the organization's current programs, how do they measure success, and who do the programs serve?


We drive and influence best-in-class medical research to develop and deliver new innovative treatments and potential cures to brain tumor patients as quickly as possible.

Patients and caregivers are our priority. We focus on groundbreaking research initiatives with the potential to translate promising science from the lab into treatments that improve survival and quality of life. We’re accelerating breakthroughs that will have a profound impact on the brain tumor community. Our research initiatives advance treatments for patients of all ages across brain tumor types so that no one is left behind. We incentivize and facilitate collaboration between pharmaceutical companies, investors, and world-class translational scientists to get the results patients need.

We also bring stakeholders together including the Food and Drug Administration (FDA), National Institutes of Health (NIH), biopharmas both large and small, oncology and neuroscience researchers, medical providers, and patients and caregivers to foster discussion and take unified action.

Population(s) Served

We equip patients and caregivers with the tools and resources to navigate every step of their unique health care journey - from understanding their diagnosis and building their medical team to making decisions about treatment, including accessing clinical trial opportunities and palliative care.

We organize events that bring the brain tumor community together to honor, learn, develop meaningful relationships, turn grief into action, and fuel momentum for our cause.

Population(s) Served

We fuel the voice and power of the brain tumor community to advocate and influence public policy. We ensure the brain tumor community’s needs are reflected in national medical research and healthcare policy decision making.

Together, we advocate for the federal government to make strategic investments in brain tumor research, improve health care delivery, reduce health disparities, and raise the priority level for our community’s urgent needs.

Over 35,000 volunteer advocates across all fifty states affect change at the local, state, and national levels annually. We coach and educate our community on policy issues so they can urge government officials to create policies that support our vision of conquering and curing brain tumors - once and for all.

Through our advocacy initiatives, we affect the lives of hundreds of thousands of Americans living with a brain tumor today, and those who will be diagnosed in the future.

Charting impact

Four powerful questions that require reflection about what really matters - results.

Conquering and curing brain tumors — once and for all.

Building on over 30 years of experience, the National Brain Tumor Society (NBTS) unrelentingly invests in, mobilizes, and unites the brain tumor community to discover a cure, deliver effective treatments, and advocate for patients and caregivers. Our organizational strategies are to use medical research funding, convening, thought leadership, and advocacy as means of enabling new treatments to be developed. In addition, our community-focused strategy aims to prepare brain tumor patients from the time of diagnosis through their health care journey while ensuring vital connections to peers and experts and to empower patients, caregivers, and researchers to be influential in public policy making. Our organizational strength strategy aims to increase NBTS’ effectiveness and value to the brain tumor community so that we can be a vehicle and platform for reaching our mission.

We break down barriers today and forge opportunities to transform brain tumor research and health care for the future. We bring together staff and volunteers with deep expertise in the scientific and health care areas that we work in, and we are empowered by the thousands of dedicated volunteers, donors, and partners we work with nationwide. Through community-based relationships and scientific, policy, and healthcare expertise, we are powering a new era of progress.

Over the last decade, our understanding of brain tumors advanced in ways we never thought possible. Now, we are poised to leverage these insights into new treatments and cures. As an example, In the past five years, NBTS has been a catalyst for change in clinical trials. As a result of those efforts, we are now seeing new clinical trials designed to evaluate more promising drugs. As a result of NBTS advocacy over the past five years, there has been an increase in federal investment in brain tumor research.

Balance sheet

Fiscal Year: Jan 01 - Dec 31

SOURCE: IRS Form 990 info

The balance sheet gives a snapshot of the financial health of an organization at a particular point in time. An organization's total assets should generally exceed its total liabilities, or it cannot survive long, but the types of assets and liabilities must also be considered. For instance, an organization's current assets (cash, receivables, securities, etc.) should be sufficient to cover its current liabilities (payables, deferred revenue, current year loan, and note payments). Otherwise, the organization may face solvency problems. On the other hand, an organization whose cash and equivalents greatly exceed its current liabilities might not be putting its money to best use.
