[Morphogenesis of cancer of the corpus uteri]

Histological assays of the endometrium in females aged over 48 (curettement performed for metrorrhagia, preparations of the corpus uteri cancer and of the uterus, taken from cadavers of persons having no genital lesions) have demonstrated atrophy and transitional mucosa on which background there occurred microadenomatosis foci in some cases. Enhancement of epithelial atypism, its proliferation and larger microadenomatosis foci, microcarcinoma foci allow microadenomatosis to be referred to as precancer proper.
