GRAND: A large-scale dataset and benchmark for cervical intraepithelial Neoplasia grading with fine-grained lesion description

•A dataset is constructed for GRAding cervical intraepithelial Neoplasia with fine-grained lesion Description (GRAND).•We benchmark a multi-rater model for our dataset.•The proposed benchmark framework achieves a comparable CIN grading accuracy to that of a professional colposcopist.
