What Zero Breast Cancer does
Mission
Zero Breast Cancer (ZBC) is a nonprofit organization founded in 1995 to investigate possible environmental causes of high incidence rates of invasive breast cancer in the San Francisco Bay Area. Zero Breast Cancer promotes breast cancer risk reduction through translation of scientific research and evidence-based recommendations that support health and wellness at key stages of life. By 2005, the Organization noted that breast cancer rates had declined in the Bay Area and that outcomes for those who have been diagnosed with breast cancer were improving. However, ZBC also noted that this disease still strikes 1 in 8 women in their lifetime and that 40,000 women die of this disease in the United States of America each year. While ZBC continues a focus on the Bay Area, outreach has extended across the globe. Breast cancer risks are not clear-cut or sudden; they are complex, they interact, and they are embedded in our physical and our social environments. Therefore, risk reduction and preve
As stated on its FY2024 Form 990.
Programs
Bridging Researchers and Community Members: From the outset, ZBC differentiated itself from other breast cancer organizations through a unique role in research. ZBC partners with scientists from universities and clinical organizations on multiple levels to represent those affected by the disease and to disseminate findings from studies focused on reducing the risk of primary/recurrent breast cancer and improving quality of life. 1) Pathways Breast Cancer Survivorship Study: Pathways is a prospective study of breast cancer survivorship following a cohort of 4,504 women diagnosed with invasive breast cancer in the Kaiser Permanente Northern California (KPNC) health-care system from 2006-2013. Under the leadership of KPNCs Department of Research and the Roswell Park Cancer Institute, ZBC and other collaborators continued to collect and analyze data with input from study participants, publish and informally share research results with multiple audiences, and expand the research.ZBC continued to facilitate and maintain the refreshed Pathways Study Community Advisory Board (CAB) with continued research advisory aims, and expanded outreach and dissemination goals, given the studys…
$281,030 spent91% of program spendingEducational and Outreach Programs: ZBC produces clear, relevant, evidence-based educational content to raise awareness of social and built environment risk factors for breast cancer and provide practical advice for how to reduce that risk. Two key strategies for reaching our intended audience are 1) to use the power of the internet to engage interested parties and 2) to partner with a variety of organizations directly serving the communities and demographics ZBC has determined to be our priorities. Our materials were readily available through frequent, multichannel digital communication initiatives, including blogs, newsletters, and frequent social media posts. Our materials were also shared at virtual and in-person health fairs and promoted in our webinar series. ZBC collaborates with community partners as part of our dissemination plan for ZBC materials to reach lower-income and higher-need communities in the greater San Francisco Bay Area and beyond. ZBC has educational resources in the following areas:1) Girls New Puberty seeks to reduce the likelihood of early puberty and therefore lifetime breast cancer risk. Current multilingual materials directed at parents and caregivers…

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2022 to 2023, from $512k to $239k (−53%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2017 3% · 2018 8% · 2019 9% · 2020 23% · 2021 36% · 2022 10%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 7 of the last 8 reported years ran a deficit.

Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.
Who funds it, year by year
2017 → 2023: the base broadened from 2 funders to 6 funders, grant income rose $62k → $64k.
2 of 12 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 1% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of ZERO BREAST CANCER’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
ZERO BREAST CANCER leans on a few funders — its largest provides 64% of grant income and the top three 88%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
99% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund ZERO BREAST CANCER.
Largest funder’s share by year: 2017 76% · 2018 83% · 2019 70% · 2020 69% · 2021 69% · 2022 40% · 2023 95% — growing more concentrated.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How long its funders stay
60% of ZERO BREAST CANCER's funders are still giving 3 years after their first grant; 75% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
95% of ZERO BREAST CANCER's grant income comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $5k arriving through sponsors registered in 2 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
