Borderline ovarian tumours are different to ovarian cancer. Although they develop from the same type of cells on the surface of the ovary known as the epithelial cells, they do not grow uncontrollably. Ovaries are a part of the female reproductive system that produces the eggs, as well as the hormones progesterone and oestrogen.
Borderline ovarian tumours are less malignant compared to other ovarian cancers and often, they are mostly unable to invade other tissues. Therefore they are usually referred to as borderline ovarian tumours instead of borderline ovarian cancer. When these tumours do spread outside the ovary, they form tumour implants (deposits) on the lining of the abdomen and on the surface of the organs in the abdomen and pelvis. The exact cause of these tumours remains unclear because of its rarity. Some risk factors associated with them include:
Use of oral contraceptives
Family history of ovarian cancer
Your age at your first period, first pregnancy and first delivery
