Ovarian cancer is defined as?

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

Answer: (D)

The key idea is understanding what defines ovarian cancer: it is a malignant tumor that arises from the ovary. That means the growth is cancerous, capable of invading nearby tissues and spreading to other parts of the body.

Describing ovarian cancer this way distinguishes it from other conditions:

• Endometriosis is when endometrial tissue grows outside the uterus, not a tumor.

• Painful menstruation is a symptom category (dysmenorrhea), not a tumor.

• Benign uterine tumors are fibroids, which are non-cancerous and arise in the uterus, not the ovaries.

So, a malignant tumor of the ovary accurately describes ovarian cancer.
