Several conditions can lead to changes in uterine volume:
Fibroids: Benign tumors that can cause an increase in uterine size. Adenomyosis: A condition where the inner lining of the uterus breaks through the muscle wall, leading to an enlarged uterus. Endometrial Hyperplasia: Thickening of the uterine lining that can cause an increase in volume. Cancer: Uterine or endometrial cancer can lead to abnormal growth and increased volume.
