  schema:description "The grade on a breast report is a sum of three scores: how much of the tumour still forms tubes, how ugly its nuclei are, and how many cells are caught dividing. Each is scored 1 to 3, and the total of 3 to 9 becomes grade 1, 2 or 3. Grade says how the cancer behaves, not how far it has spread."@en ;
