Ovarian Cancer

What Are The Types of Ovarian Cancer?

The site/location in the ovary and the nature of the cancerous cell in the female reproductive system where ovarian cancer originates determine the type of ovarian cancer of the patient. Ovarian cancer can be of the following types:

  1. Epithelial tumours – These tumours sprout up from the external layer epithelium enveloping the ovary. Statistics reveal that about 90 percent of tumors of ovarian cancer are epithelial tumours. Most of the epithelial tumours are benign (non-cancerous) and the common varieties of benign tumours include serous adenomas, mucinous adenomas and Brenner tumours. Epithelial ovarian carcinoma is the result of environmental and dietary factors. These factors include the use of talc on the perenium/the area between anus and vulva (and on vulva itself), asbestos, pelvic irradiation, viruses (mainly mumps), fat-rich diet and lactose consumption. The other relevant factors pertain to increased number of ovulation cycles: low parity (low number of pregnancies), delayed childbearing, early menarche (first occurrence of menstruation) and late menopause.

  2. Stromal tumours – Hormone producing cells are the source of developing cancerous tumors in which the unwanted abnormal genetic change occurs leading to further proliferation. The ill-formed underperforming cells which were supposed to secret hormones are called stromal tumours.​

  3. Germ-cell tumours – The cells that are responsible for production female gametes (ova) are sometimes unfortunately subject to doleful genetic mutation in their DNA resulting in formation of inimical obnoxious defective cells which tend to grow in number unabatedly. Such a collection of cancerous cells are referred to as germ-cell tumours. The most common varieties of germ-cell tumors are maturing teratomas, dysgerminomas and endothermal sinus tumors. The majority of victims of germ-cell cancerous tumors are teenager girls or women in their twenties. Nevertheless, about ninety percent germ-cell malignancies are curable and their fertility can be preserved.

The factors that decrease the risk of ovarian cancer are increased number of ovulation cycles a woman undergoes, breastfeeding, multiparity/higher incidences of foetal births etc. Use of oral contraceptives for longer periods has been observed to be a reason in reducing the occurrence of ovarian cancer.  The risk of ovarian cancer has been low in the females who underwent hysterectomy (surgical removal of uterus) and tubal ligation (surgical severance of fallopian tubes/complete blockage of fallopian tubes by external fastening).
