Ovarian Cancer: A Deadly Silent Killer

I was called to the emergency room in the hospital to see M as she was screaming in pain. She had intermittent mild abdominal cramps and bloating for the past one week. She did not pay much attention as she thought it was due to some spicy food she ate over the weekend.

M, 50, was rolling in pain when I saw her. Her abdomen was hard and bloated. When she was more settled, I could feel a huge mass in her lower abdomen. An urgent MRI (Magnetic Resonance Imaging) of the abdomen revealed a large left ovarian mass measuring 20 cm x 14cm x 11cm. It was a multiloculated cyst with many partitions and fluid-filled sacs. Some of the sacs had solid frond-like growth and one of these showed signs of bleeding. The abdomen was also filled with ascitic fluid and there were solid tumors on the omentum (a large flat fatty tissue covering the ovary) and the peritoneum (lining of the abdomen cavity). M was suffering from an advanced stage of ovarian cancer.

How common is Ovarian Cancer?

According to the Singapore Cancer Registry, ovarian cancer is the second most common female genital cancer and the fifth commonest cancer among women in Singapore. Its incidence is rising in recent years.

Ovaries contain 2 types of cells: epithelial cells and germ cells. Epithelial cell cancer is more common than germ cell cancer. The former occurs more often among older women while the latter affects younger women.

Why is ovarian cancer deadly?

Ovaries are located deep in the pelvic cavity and hidden away. As a result, early cancerous changes are more difficult to detect. By the time these changes occur, the tumor is usually in the later stages of development and spread.

Besides, in early stages, ovarian cancer seldom has symptoms and signs and they are usually non-specific such as bloating and indigestion. Screening tests like blood tumor markers and ultrasound examination may also not be as effective.
