Ovarian cancer refers to a malignant (cancerous) growth arising from different parts of the ovaries. The ovaries are the part of a woman’s reproductive system where eggs are developed.
Ovarian cancer is the fifth most common cancer in Singapore, with more than 300 cases diagnosed yearly.1
90% of ovarian cancers are ‘epithelial’, meaning they arise from the surface (epithelium) of the ovary. Epithelial ovarian cancers tend to occur more in older women. The remaining 10% of ovarian cancers arise from the egg cells (germ cell tumour) or supporting cells (sex cord-stromal tumour). Germ cell cancers of the ovary occur more frequently in younger women.
