Mitotic figures are counted only at the periphery of the tumor, and counting should begin in the most mitotically active areas, and in at least 10 high-power fields (HPFs). If you know that the area of your high power field is about 0.2mm<sup>2</sup>, then you may score mitotic count as follows:<ref name=cap-invasive>{{cite web|url=https://documents.cap.org/protocols/Breast.Invasive_4.7.0.1.REL_CAPCP.pdf|Protocol for the Examination of Resection Specimens from Patients with Invasive Carcinoma of the Breast Version: 4.7.0.1 - Table 1.
