Endometriosis is defined as ...

• A. Endometrial tissue located outside the uterus
• B. Inflammation of the cervix
• C. Benign tumors in the uterus
• D. Malignant tumor of the ovary

Answer: (A)

Endometriosis means endometrial tissue is located outside the uterus. This tissue still responds to menstrual hormones, so it can bleed when a person has a period, causing inflammation, pain, and scar tissue in places like the ovaries, pelvic lining, and other areas. That’s why symptoms often include pelvic pain and sometimes infertility, since these ectopic implants can affect normal pelvic anatomy and function.

The other descriptions are different conditions: inflammation of the cervix is cervicitis; benign uterine tumors are fibroids; a malignant tumor of the ovary is ovarian cancer. Endometriosis is specifically ectopic endometrial tissue outside the uterus.
