Financial aid. Support groups. Free experiences. Connections to the organizations that can actually help. We summarize available resources across many organizations to provide free guides. Every resource on FIGHT4 is personally reviewed by young adults who have been through different treatments — because we have used most of them ourselves.
Four pillars, one mission: no one fights alone.
Our framework for building resources and community, how we support young adults with cancer worldwide.
Cut through the noise
Combing through available resources can be overwhelming. We do the work of finding, summarizing, and organizing — so you don't have to.
Break the stigma
Conversations about topics that feel taboo or difficult are how we build understanding, community, and courage in young adults facing cancer.
One centralized library
Financial aid, support groups, free experiences, connections to major organizations — all in one place, filterable by your situation.
No matter where you are
Cancer doesn't stop at borders. Our library is curated with an international mindset, connecting young adults to resources worldwide.

"My oncologist said it was as rare as seeing a penguin in the wild... wearing a top hat... and shoes... and a sparkly bowtie."
The cancer had gotten into my central nervous system. The average age at diagnosis for SMZL is 65–70 years old. My oncologist said it was as rare as seeing a penguin in the wild... wearing a top hat... and shoes... and a sparkly bowtie.
Not just a website. A movement already underway.
FIGHT4 grew out of Natalia's 2024 Blood Cancer United Visionaries of the Year campaign in San Diego.
What do you fight 4?
#WhatDoYouFight4 is more than a hashtag. It's a call to action for anyone touched by cancer to share their story, their purpose, and what keeps them going.
Questions, answered.
What people ask us most.
Natalia, who was diagnosed with Splenic Marginal Zone Non-Hodgkin's Lymphoma at 23, personally reviews every resource. Over time, a small group of young adult survivors will join the vetting team — but every resource is always reviewed by someone who has been in treatment.
Yes. Completely free. Always. There is no paywall, no premium tier, and no sales pitch. This is a nonprofit resource built to be used.
Ask F4 only draws from resources we have personally reviewed. It does not scrape the open web, does not make things up, and does not give medical advice. If it can't find a vetted match for your situation, it tells you — instead of hallucinating an answer.
Yes — this entire site is bilingual (use the EN/ES toggle in the top right), and we specifically prioritize Spanish-language resources and bilingual providers. Natalia is a Community Outreach Volunteer for Blood Cancer United's Spanish Education Programs.
Send us an email at hello@fight4foundation.org with the name of the organization, what they do, and (if you've used them) what your experience was. We review every suggestion before adding it to the library.
