The most effective place to donate depends on what matters most to you: funding lab research, supporting patients living with a diagnosis, or targeting a specific type of breast cancer. Several highly rated organizations put the vast majority of donations toward their mission, but they differ in focus, scope, and how your money gets used. Here’s how to choose.
Top-Rated Breast Cancer Charities
Charity Navigator, the largest independent evaluator of U.S. nonprofits, scores breast cancer organizations on financial health, accountability, and transparency. The highest-rated options as of 2025:
- National Breast Cancer Foundation: 100% score
- CancerCare: 100% score
- Breast Cancer Research Foundation (BCRF): 98% score
- Living Beyond Breast Cancer: 97% score
- Susan G. Komen: 94% score
These scores reflect how well each organization manages its finances and reports to the public. They don’t tell you what the money actually funds, which varies significantly from one group to the next.
If You Want to Fund Research Directly
The Breast Cancer Research Foundation is the standout choice for donors whose priority is getting money into laboratories. BCRF directs 88 cents of every dollar raised toward research grants, one of the highest ratios among cancer charities. Since 1993, the foundation has raised more than $300 million for research.
That funding has contributed to real medical breakthroughs. BCRF-supported work helped develop the first targeted therapy for HER2-positive breast cancer, approved in 1998, which cut the risk of recurrence by 50 percent. More recently, BCRF-funded research contributed to a treatment approved in 2021 specifically for triple-negative breast cancer, an aggressive subtype that had fewer options. These are drugs that changed survival odds for hundreds of thousands of people.
If You Want to Target Metastatic Breast Cancer
Metastatic breast cancer, meaning cancer that has spread beyond the breast, is responsible for nearly all breast cancer deaths. Yet it historically receives a fraction of overall research funding. METAvivor is the only U.S. nonprofit that exclusively funds metastatic breast cancer research, using a peer and patient advocate review process to select projects. If you want every dollar going toward stage 4 research specifically, this is the most direct route.
If Health Equity Matters to You
Susan G. Komen, the largest and most recognized breast cancer organization, has shifted its research priorities in recent years toward precision medicine, health disparities, and aggressive cancer subtypes. Komen-funded research has produced over 1,500 discoveries focused on metastatic and deadly breast cancers, with nearly 900 centered on potential treatments. Another 600-plus discoveries address strategies to reduce disparities in who gets breast cancer and who survives it.
One Komen-funded finding illustrates why this work matters: Black women living in disadvantaged neighborhoods had worse breast cancer outcomes regardless of what stage they were diagnosed at, what treatments they received, or their lifestyle factors. That kind of research points toward systemic changes, not just new drugs, and Komen is one of the few large organizations funding it at scale.
If You Want to Support Patients, Not Just Labs
Not every effective donation goes to a microscope. Living Beyond Breast Cancer (97% Charity Navigator score) focuses on education and support for people at every stage of diagnosis. CancerCare (100% score) provides free counseling, support groups, and financial assistance to people dealing with any cancer, including breast cancer. These organizations fill gaps that research funding alone can’t address, particularly for people navigating treatment costs, emotional distress, or end-of-life decisions.
The National Breast Cancer Foundation (100% score) splits its focus between early detection programs, patient navigation services, and research support. It’s a good option if you want a single donation to cover multiple needs.
International Research Funding
Worldwide Cancer Research takes a different approach. Based in the UK, it funds discovery research into any cancer type, anywhere in the world. Since 1979, it has invested in over 2,000 research projects across dozens of countries. If you want your donation to reach scientists who might not have access to U.S. funding pipelines, this organization casts the widest geographic net.
Ways to Give Beyond Cash
Most major breast cancer charities accept more than credit card donations. BCRF, for example, accepts stocks and securities, IRA charitable rollovers, workplace matching gifts, donor-advised funds, and even Delta frequent flyer miles. You can also include a bequest in your will for a legacy gift.
Donor-advised funds are worth knowing about if you have appreciated investments. You contribute assets like stocks to the fund, take an immediate tax deduction, and then direct grants to your chosen charity over time. BCRF works with major DAF providers like Fidelity and Schwab, and most other large breast cancer organizations do as well.
If your employer offers a matching gift program, that’s one of the simplest ways to double your impact. Check with your HR department before donating, since some companies will match contributions to any qualified 501(c)(3) organization.
Tax Deductions for Charitable Giving
All of the organizations listed above are registered 501(c)(3) nonprofits, meaning your donations are tax-deductible if you itemize. For cash contributions, you can generally deduct up to 60 percent of your adjusted gross income. Donations of stocks or other non-cash assets follow different limits, typically 20 to 30 percent of AGI depending on the type of asset and the organization. If your total charitable giving in a year exceeds these caps, you can carry the excess forward to future tax years.
How to Choose
Start with what you care about most. If your priority is getting money into the hands of researchers working on new treatments, BCRF gives you the best ratio of donations to research grants. If metastatic breast cancer is personal to you, METAvivor is the most focused option. If you believe health equity is inseparable from cancer outcomes, Komen’s current priorities align with that. If someone you know is going through treatment right now and needs practical support, Living Beyond Breast Cancer and CancerCare fill that role.
Splitting a donation across two or three organizations is perfectly reasonable. A common approach is to put the bulk toward research funding and a smaller portion toward patient support, covering both the long-term fight and the immediate human need.
