Question: what is figo grade 1?
Answer: According to current practice standards, EECs are assigned a FIGO grade based on the degree of glandular differentiation. Grade 1 tumors exhibit ≤5% solid nonglandular, nonsquamous growth; grade 2 tumors from 6% to 50%; and grade 3 tumors >50% 1–3. The presence of marked cytologic atypia increases the grade 1 level.
