The tissue in the body is made up of cells. With cancer, the cells multiply uncontrollably, which leads to a malignant neoplasm (abnormal growth of tissue) developing. The cancer cells can destroy the healthy tissue and spread throughout the body.

The cancer cells have spread in your body and multiplied at another site. These are called metastases.

The ovaries are part of the female genitals. There are two ovaries, one on each side. The ovaries sit low down in the abdomen. Egg cells mature in the ovaries. The egg cells can later develop into a child. The ovaries also produce various messenger substances.
