# CancerVerse: A Fully Open Longitudinal and Multimodal Dataset for Multicancer Screening

[![CancerVerse Dataset](https://img.shields.io/badge/CancerVerse-Dataset-FF4040.svg)](#cancerverse-dataset) [![CancerVerse Benchmark](https://img.shields.io/badge/CancerVerse-Benchmark-FF4040.svg)](https://papers.miccai.org/miccai-2026/paper/0562_paper.pdf) [![CancerVerse Paper](https://img.shields.io/badge/CancerVerse-Paper-FF4040.svg)](https://papers.miccai.org/miccai-2026/paper/0562_paper.pdf)

We present **CancerVerse**, a fully open longitudinal and multimodal CT dataset for multicancer screening. It contains **24,422** CT scans from **14,599** patients, followed over time for up to 14.4 years. CT scans were collected at hospitals in Switzerland and Turkey from 2010 to 2025. Human experts drew voxel-wise tumor annotations for **13** cancer types in the pelvis, abdomen, and chest. CT scans are paired with radiology reports, pathology results and clinical variables. CancerVerse also includes CT scans of verified healthy patients for measuring false positives.

As the first large-scale open dataset of its kind, CancerVerse offers a new benchmark for detecting cancer early at a low rate of false positives per scan. It is built and maintained by the [BodyMaps](https://huggingface.co/BodyMaps) team.

## CancerVerse Dataset

<details>
<summary>Set up the environment (optional)</summary>

```bash
conda create -n huggingface python=3.11 -y
conda activate huggingface
python -m pip install --upgrade pip
python -m pip install --upgrade "huggingface_hub[cli]"
hf --version
hf auth login
```

This creates a clean conda environment with the Hugging Face command-line tool. Logging in is optional; it gives higher download rate limits.

</details>

### Four lines of code to download the dataset

```bash
mkdir CancerVerse && cd CancerVerse
hf download BodyMaps/CancerVerse download_CancerVerse_data.sh download_CancerVerse_label.sh --repo-type dataset --local-dir .
bash download_CancerVerse_data.sh  # CT volumes and metadata, needs ~3 TB
bash download_CancerVerse_label.sh # tumor annotations, needs ~40 GB
```

After both scripts finish:

### Dataset at a glance

| | CancerVerse |
|---|---:|
| CT scans | **24,422** |
| patients | **14,599** |
| studies | **22,344** |
| cancer types with voxel-wise tumor annotations | **13** |
| tumor annotations | **12,529** |
| follow-up of these patients | **1 day to 14.4 years** |
| study dates per patient | **up to 26** |
| acquisition years | **2010 to 2025** |


### Voxel-wise tumor annotations

The annotation took 28 human experts more than 13 months: radiology residents drew the annotations, and eight board-certified radiologists reviewed them independently. Disagreements were resolved by adjudication.
