+# 🩻 CancerVerse
+
+### The first **longitudinal**, **multimodal** CT dataset spanning **13 malignant tumor types**
+
+CancerVerse pairs whole-body abdominal/pelvic **CT volumes** with the **radiologists' own free-text reports**, follows patients **across time**, and is being released in stages — culminating in **expert voxel-level tumor masks** and a deep **clinical & longitudinal annotation layer**. It is built to power the next generation of cancer-aware medical AI: tumor detection and segmentation, report generation and grounding, longitudinal disease modeling, and treatment-response prediction.
+
+> **24,168 CT volumes · 13,863 patients · 24,168 paired radiology reports · 15 years of follow-up · 13 cancer types — fully de-identified.**
+
+CancerVerse is built and maintained by the [BodyMaps](https://huggingface.co/BodyMaps) team.

+
+## 🚀 Staged Release — what's ready today, what's coming next
+
+CancerVerse is continuously evolving. We are releasing it in stages so the community can start building today while the richest layers are finalized.
+
+### ✅ Available now
+
+- **De-identified CT volumes** — 24,168 3D scans from 13,863 patients, across multiple scanners and **4 contrast phases**.
+- **Paired radiology reports** — the radiologist's full free-text impression for 24,168 scans. Real clinical language, ready for report generation, information extraction, and image–text pre-training.
+- **Scan-level context** — sex, age, exam date, contrast phase, scanner, and study/series/protocol descriptions for every volume.
+- **Longitudinal linkage** — stable de-identified patient IDs + exam dates let you reconstruct each patient's imaging timeline (up to **26 timepoints**, spanning up to **14.4 years**).
+
+### 🔜 Coming soon
+
+- 🧬 **Structured tumor features** *(by August 2026)* — per-organ malignancy status, largest-lesion **diameters, locations, attenuation**, and **tumor staging**.
+- 🔬 **Pathology results** *(by August 2026)* — ICD-10 codes.
+- 🎯 **Expert manual segmentation annotations** *(by September 2026)* — voxel-level, radiologist-verified **tumor** annotations.
+- 📋 **Clinical & longitudinal layer** *(by September 2026)* — cancer histology, TNM stage, treatments received, surgical resections, **RECIST treatment response**, metastatic sites, disease-status narratives, follow-up recommendations, comorbidities, and devices/implants.
+
+> 💡 *Cancer information is already in your hands today — it lives in the paired radiology reports. The structured, machine-readable labels and masks make it turnkey, and arrive in the next releases.*
+

+
+## 🎯 The 13 malignant tumor types
+
+CancerVerse is curated around 13 abdominal and pelvic malignancies:
+
+`liver` · `kidney` · `pancreas` · `colon` · `adrenal gland` · `bladder` · `duodenum` · `esophagus` · `gallbladder` · `prostate` · `spleen` · `stomach` · `uterus`
+
+---
+
+## 📦 What's inside this release
+
+Each row is **one CT volume**, paired with that scan's radiology report and acquisition context.
+
+| Field | Description |
+|---|---|
+| `CancerVerse ID` | Unique de-identified identifier for the CT volume (one per scan). |
+| `Patient ID` | De-identified patient identifier — **links a patient's scans across time**. |
+| `Encrypted Accession Number` | De-identified study/visit identifier. |
+| `sex` | Patient sex (M / F). |
+| `age` | Patient age at the time of the scan (years). |
+| `exam_date` | Date of the CT exam (enables longitudinal ordering). |
+| `phase` | Contrast phase (e.g., portal-venous, arterial early/late, non-contrast). |
+| `scanner` | Scanner model / vendor. |
+| `study_description`, `series_description`, `protocol_name` | Acquisition protocol details. |
+| `report` | **Free-text radiology report**. |
+
+The CT volumes themselves are provided alongside this table and are linked by `CancerVerse ID`.

+## ✨ Why CancerVerse?
+
+- **Truly longitudinal.** Most public CT datasets are single snapshots. CancerVerse follows real patients over **up to 14.4 years and 26 timepoints**, enabling disease-progression and treatment-response research.
+- **Multimodal from day one.** Every scan ships with its **radiologist report** — pixels *and* clinical language — ideal for vision-language pre-training, report generation, and grounded detection.
+- **Cancer-centric.** Purpose-built around **13 malignant tumor types**, with expert masks and structured oncology labels on the way.
+- **Real-world scale & diversity.** 13,863 patients, multiple scanners, and 4 contrast phases — clinical heterogeneity, not a sanitized benchmark.
+- **Responsibly de-identified.** No protected health information; stable de-identified IDs preserve patient timelines for research.
