Ovarian cancer overview
Cancer occurs when cells undergo a transformation and begin to grow and multiply without normal controls. As the cells grow and multiply, they form masses called tumours. Cancer is dangerous because it overwhelms healthy cells by taking their space and the oxygen and nutrients they need to survive and function.
Ovarian cancer occurs when a tumour forms in one or both of a woman's ovaries. The ovaries are a pair of small organs that produce and release ova, or human eggs. The ovaries also produce important hormones such as oestrogen and progesterone. They are located in the lower abdomen (pelvis), on either side of the womb (uterus). Ova released by the ovaries travel through the fallopian tubes to the uterus, where they may or may not be fertilised by the male sperm.
