# Cancer charities in the UK — how to compare before you donate

**In short:** Cancer giving splits between research funders and patient-support organisations. There is no single best cancer charity — match the model to your intention, then compare Clarity Scores and cause spend on CharityCompare.

Data from [CharityCompare editorial](https://register-of-charities.charitycommission.gov.uk/), last updated 12 August 2026.

## What cancer charities do

“Cancer” covers research laboratories, national support lines, disease-specific funds and local services. Before you compare ratings, decide whether you want **future treatments**, **help for people living with cancer now**, or a **specialist** focus.

## Which cancer charity is best to donate to?

There is no single best answer. A strong process:

- Verify the [charity number](https://www.charitycompare.org.uk/guides/how-to-check-a-charity-number).

- Match research vs support vs specialist.

- Compare filings and Clarity Score beacons [side by side](https://www.charitycompare.org.uk/compare-charities).

- Read the full guide: [compare cancer charities UK](https://www.charitycompare.org.uk/guides/compare-cancer-charities-uk).

## Head-to-head starting point

- **[Macmillan vs Cancer Research UK](https://www.charitycompare.org.uk/compare/macmillan-vs-cancer-research-uk)** — support vs research

- **[Marie Curie vs Macmillan](https://www.charitycompare.org.uk/compare/marie-curie-vs-macmillan)** — hospice and end-of-life nursing vs living-with-cancer support

## Efficiency and overheads

If you are searching for efficient cancer charities, use **cause spend** and fundraising cost in context — not the lowest admin slogan. See [charity admin costs UK](https://www.charitycompare.org.uk/guides/charity-admin-costs-explained).
