Final answer:
The most common benign gynaecological lesion is Uterine fibroids, which are noncancerous growths of the uterus. Ovarian cysts and endometriosis are also frequent issues but are not the most common lesions. Cervical dysplasia is a potentially precancerous condition affecting the cells on the cervix's surface.
Step-by-step explanation:
The most common benign gynaecological lesion is A) Uterine fibroids. Uterine fibroids are noncancerous growths of the uterus that often appear during childbearing years. Fibroids are made of muscle cells and other tissues that grow in and around the wall of the uterus, or womb. They range in size from seedlings, undetectable by the human eye, to bulky masses that can distort and enlarge the uterus.
Ovarian cysts are also common and manifest as a fluid-filled sac within the ovary. While most ovarian cysts are benign and often dissolve on their own without treatment, some may cause symptoms and require medical intervention. Endometriosis is characterized by tissue similar to the lining inside the uterus growing outside it, causing pain and potentially leading to infertility. Cervical dysplasia refers to abnormal changes in the cells on the surface of the cervix that can be precancerous.
