The ovary is the female reproductive organs that produce eggs and the female hormones oestrogen and progesterone. Ovarian cancer develops when cells in the ovaries begin to grow out of control.
Ovarian cancer is the fourth most common cancer among women in Peninsular Malaysia, making up 5% of all female cancer cases, according to the Malaysian National Cancer Registry, 2007-2011.
Types of Ovarian Cancer
- Ovarian epithelial cancer – spread to the lining and organs of the pelvis and abdomen.
- Germ cell tumors – Tumours may appear in the egg-producing cells of the ovaries.
- Sex cord-stromal tumours – Develop from the stroma tissue cells that produce the female hormones estrogen and progesterone.
- Ovarian sarcoma – Develop in the connective tissues of ovarian cells.
- Krukenberg tumours- Spreads into the ovaries from other organs.
- Ovarian cysts: Ovarian cysts are fluid-filled sacs that develop inside the ovary.
Staging of Ovarian Cancer
Staging of ovarian cancer refers to the extent to which it has spread to other organs or tissues.
The stages of ovarian cancer inclusive of:
|I||The cancer is confined to the ovaries.|
The cancer is in one or both ovaries and has spread to the pelvic regions.
|III||The cancer is in one or both ovaries, and cancer has either spread beyond the|
pelvis to the lining of the abdomen or to the lymph nodes in the back of the abdomen.
|IV||In the most advanced stage of ovarian cancer, cancer has metastasized to distant|
sites, such as the inside of the spleen, liver, lungs or other organs outside the abdomen and pelvic region.
Like many cancers, ovarian cancer may not produce symptoms in the early stages. However, at an advanced stage, the common symptoms include:
- Abdominal bloating or a feeling of pressure
- Abdominal/pelvic pain
- Frequent urination
- A feeling of fullness even after a light meal
- Unexplained weight gain/loss
- Abnormal vaginal bleeding
- A pelvic examination – First steps in evaluating a patient with a known or suspected diagnosis of ovarian cancer.
- Ultrasound – Uses sound waves to create an image of internal organs, including the ovaries, uterus and cervix.
- Computerized Tomography (CT) scan – Used to help diagnose ovarian, fallopian tube or peritoneal cancer.
- Magnetic resonance imaging (MRI) – To detect tumors or recurrences in other areas of the body, such as the head.
- Positron emission tomography (PET) scan – is an imaging test that helps reveal how your tissues and organs are functioning. A PET scan uses a radioactive drug (tracer) to show this activity. This scan can sometimes detect disease before it shows up on other imaging tests.
- Surgery – To locate and remove visible signs of cancer in a process called debulking.
- Chemotherapy – To deliver high doses of chemotherapy drug combinations to tumours, while reducing damage to the rest of your body.
- Radiotherapy – Delivery of high dose radiation to kill the cancer cells.
- Targeted therapy – To block the enzyme poly ADP-ribose polymerase (PARP) from identifying damaged DNA inside cancer cells, PARP inhibitors may stop cancer cells from repairing themselves.
