Ovarian cyst. Endoscope view of a cyst (swelling) in a patient's ovary (white). At top centre is the uterus (womb) with its two fallopian tubes on either side. Cysts, fluid-filled sacs, are quite common in women of child-bearing age. They are rarely malignant (cancerous) and usually shrink and disappear over time.
