What Edith Sanford Breast Cancer Foundation does
Mission
The mission of the Edith Sanford Breast Cancer Foundation is to unlock each woman's genetic code to advance today's prevention and treatment, and end breast cancer for future generations.
As stated on its FY2018 Form 990.
Program
The Foundation is a supporting organization whose mission is to raise funds for the groundbreaking research conducted by Edith Sanford Breast Cancer Research and in collaboration with Sanford Health, the Foundation's research and patient care partner. Thanks to a transformational gift from Denny Sanford to cover operating expenses, every private contribution is directly invested in the research and patient care programs of Edith Sanford.
The first program described on its most recent Form 990, which lists programs largest first by expense.
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 2017 to 2018, from $16M to $0 (−100%).
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.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 1 of the last 2 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 → 2021: the base narrowed from 2 funders to 1 funder, grant income fell $11k → $700.
2 of 4 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 97% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
Left out of every figure on this page: $1.2M from one payer (the payer shares this organization's board, largest Sanford Group Return). These are real filings, and they are not money Edith Sanford Breast Cancer Foundation raised.
From the IRS filings of Edith Sanford Breast Cancer Foundation’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving.

How concentrated its funding is
Edith Sanford Breast Cancer Foundation leans on a few funders — its largest provides 80% of grant income and the top three 99%; 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 Edith Sanford Breast Cancer Foundation.
Largest funder’s share by year: 2017 53% · 2018 99% · 2021 100% — 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.
Where its funders are
97% of Edith Sanford Breast Cancer Foundation's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $950 that is directly attributable, 100% of it comes from funders outside South Dakota, across 2 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $28k 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.
