Cancer Registry - Tumor Characteristics

This cancer registry dataset provides detailed, standardized information on tumor characteristics, including primary site, histology, stage, grade, size, lymph node involvement, metastasis, biomarker results, and treatment details for SEER reporting and outcomes tracking. It enables comprehensive analysis of cancer patterns, treatment efficacy, and patient outcomes across diverse populations.

Behind this dataset

Same schema. As many rows as you need.

These 100 rows came out of a blueprint — 23 columns with generation rules behind each one. Open it in Data Factory to retune a column, add your own, wire in foreign keys, and run it at the size you actually need.

Rules it was built with
  • Registry ID unique per cancer diagnosis
  • Patient demographics and medical record number
  • Primary site: ICD-O-3 topography code
  • Histology: ICD-O-3 morphology code
  • Behavior: benign, uncertain, in situ, malignant
  • Grade: well, moderately, poorly differentiated, undifferentiated
  • TNM staging: clinical stage and pathologic stage
  • AJCC stage group (I, II, III, IV)
