area of ventral prostate occupied by tumorous lesions to total ventral prostate area ratio area of ventral prostate occupied by tumorous lesions with round, irregular size nuclei to total ventral prostate area ratio 2021-04-01T14:38:47Z A calculated measurement in which the area of the ventral prostate gland occupied by tumorous lesions with round, irregular size nuclei is divided by the total area of the ventral prostate gland, and the result presented as a ratio, fraction, quotient or percentage. A tumorous lesion is one which is or has the potential to become a tumor, that is, a neoplasm or new growth of tissue in which cell multiplication is more or less uncontrolled and progressive. Tumorous lesions include tumors and preneoplastic lesions, as well as hyperplastic lesions composed of histologically normal cells.
