An ovarian cyst is a collection of fluid inside an ovary. Most ovarian cysts occur as a normal part of the process of ovulation (egg release) -- these are called functional cysts. These cysts usually go away within a few months without any treatment.

The ovary is a ductless reproductive gland in which the female reproductive cells are produced. Females have a pair of ovaries, held by a membrane beside the uterus on each side of the lower abdomen. The ovary is a ductless reproductive gland in which the female reproductive cells are produced. Females have a pair of ovaries, held by a membrane beside the uterus on each side of the lower abdomen. The ovary is needed in reproduction since it is responsible for producing the female reproductive cells, or ova.

Ovarian cancer is a type of cancer that begins in the ovaries. The ovaries — each about the size of an almond — produce eggs (ova) as well as the hormones estrogen, progesterone and testosterone. Ovarian cancer is a type of cancer that begins in the ovaries. Women have two ovaries, one on each side of the uterus. The ovaries — each about the size of an almond — produce eggs (ova) as well as the hormones estrogen and progesterone. Ovarian cancer often goes undetected until it has spread within the pelvis and abdomen. At this late stage, ovarian cancer is more difficult to treat and is frequently fatal.

This type of cancer can occur in women who still have their ovaries, but it is of more concern for women who have had their ovaries removed to prevent ovarian cancer. This cancer does rarely occur in men.

Cancer is a disease in which abnormal cells in the body grow out of control. Cancer is always named for the part of the body where it starts, even if it spreads to other body parts later. Ovarian cancer is a group of diseases that originates in the ovaries, or in the related areas of the fallopian tubes and the peritoneum. Women have two ovaries that are located in the pelvis, one on each side of the uterus. The ovaries make female hormones and produce eggs. Women have two fallopian tubes that are a pair of long, slender tubes on each side of the uterus. Eggs pass from the ovaries through the fallopian tubes to the uterus. The peritoneum is the tissue lining that covers organs in the abdomen. Ovarian cancer causes more deaths than any other cancer of the female reproductive system. But when ovarian cancer is found in its early stages, treatment works best. Ovarian cancer often causes signs and symptoms, so it is important to pay attention to your body and know what is normal for you.

The tissues of the ovaries are arranged into several distinct layers: 1  The outmost layer of simple epithelium, known as the germinal epithelium, forms a soft, smooth covering for the ovary. 2  The tunica albuginea is a thick band of tough fibrous connective tissue just below the germinal epithelium.

The ovaries are made up of 3 main kinds of cells. 1  Each type of cell can develop into a different type of tumor: 2  Epithelial tumors start from the cells that cover the outer surface of the ovary. Most ovarian tumors are epithelial cell tumors. 3  Germ cell tumors start from the cells that produce the eggs (ova).

Ovarian cancer begins in the ovaries. Ovaries are reproductive glands found only in females (women). The ovaries produce eggs (ova) for reproduction. The eggs travel through the fallopian tubes into the uterus where the fertilized egg implants and develops into a fetus. The ovaries are also the main source of the female hormones estrogen and progesterone. One ovary is on each side of the uterus in the pelvis.

Benign tumors can be treated by removing either the ovary or the part of the ovary that contains the tumor. Malignant (cancerous) or low malignant potential ovarian tumors can spread (metastasize) to other parts of the body and can be fatal. Their treatment is discussed later in this document.
