BreastPathDB

BreastPathDB is a breast cancer histopathology dataset for whole-slide image based subtype classification. It contains 770 de-identified whole-slide images, including 165 H&E slides and 605 IHC slides, with clinical subtype labels, curated metadata, and patient-level train/validation/test splits.

The dataset is intended for computational pathology benchmarking, weakly supervised WSI classification, and cross-cohort method development.

Dataset Contents

• H&E and IHC whole-slide images in SVS format.
• Breast cancer subtype labels based on clinical IHC surrogate categories.
• Structured metadata file: BreastPathDB.csv.
• Patient-level data splits to reduce leakage during model evaluation.
