Ovarian cancer is a disease in which malignant (cancer) cells form in the ovaries.
The ovaries are a pair
of organs in the female reproductive
system. They are in the pelvis, one on each side of the
uterus (the hollow, pear-shaped
organ where a fetus grows). Each
ovary is about the size and shape of an almond. The ovaries make eggs and
female hormones (chemicals that
control the way certain cells or
organs work in the body).
Ovarian cancer is the leading cause of death from cancer of the female reproductive system.
Since 1992, the number of new cases of ovarian cancer has stayed about the same. The number of deaths from ovarian cancer has slightly decreased since 2002.
It is hard to find ovarian cancer early. Early ovarian cancer may not cause any symptoms. When symptoms do appear, ovarian cancer is often advanced.
