The National Pediatric Cancer Foundation is dedicated to funding research to eliminate childhood cancer. Their focus is on finding less toxic and more effective treatments for pediatric cancer, as many current treatments were originally developed for adults.
They formed the “Sunshine Project,” a business model that capitalizes on the strengths of different researchers from various institutions to fast-track new treatments and clinical trials. This collaborative approach reduces duplication and speeds up results.
Why They’re Trusted:
- Perfect Score: 100/100 rating on Charity Navigator.

How to Choose the Right Cancer Charity
When selecting a cancer nonprofit beyond this list, consider:
- Research vs. Support – Decide if you want your money to fund scientists (CRI, BCRF) or help patients with bills and rides today (ACS, NBCF).
- Specific vs. General – General organizations like ACS cover all cancers, while specific ones (MMRF, OCRA) focus intensely on one disease type.
- Financial Transparency – Review the organization’s “Form 990” on their website to see exactly where money goes.
- Impact Measurement – Look for “impact reports” that list specific clinical trials funded or number of patients served, rather than vague awareness metrics.
- Program Expense Ratio – Ensure at least 70-75% of expenses are program-related. Cancer marketing is expensive, so avoid charities that spend most of their budget on mailers.
Frequently Asked Questions
What makes a cancer charity trustworthy?
Trustworthy cancer charities invest the majority of their funds (70%+) into research or patient programs rather than fundraising. They have transparent financials, independent board oversight, and clear, measurable goals—such as funding specific clinical trials or providing free screenings to a set number of people.
Why do some cancer charities have lower ratings?
Some cancer charities rely heavily on direct mail or telemarketing, which are expensive ways to raise money. This lowers their “program expense ratio,” hurting their ratings. It is generally better to support organizations that have efficient fundraising methods.
Can I donate to a specific type of cancer research?
Yes. Most large organizations (like the American Cancer Society) allow you to “restrict” your donation to a specific type of cancer. Alternatively, you can donate to a disease-specific nonprofit like the Lung Cancer Foundation of America.
How much of my donation should go to programs vs. overhead?
A strong benchmark is 75% or higher. However, remember that “overhead” includes essential things like auditing, compliance, and the staff who manage the research grants. 100% efficiency is rarely possible unless overhead is covered by a separate endowment (like at St. Jude).
What’s the difference between Charity Navigator and GuideStar?
Charity Navigator rates charities based on numbers (financial health and accountability), awarding 0-4 stars. GuideStar (Candid) awards transparency “Seals” (Bronze to Platinum) based on how much information the nonprofit publicly shares about its mission and results.
