Ovarian cancer and the menopause
The risk of developing ovarian cancer increases after the menopause, although menopause itself is not the cause of this cancer.
Ovarian cancer symptoms can be hard to distinguish from those caused by other conditions. Early ovarian cancer symptoms include persistent bloating, persistent pelvic and abdominal pain, and trouble eating.
In many cases, ovarian cancer is not diagnosed until the cancer has spread to other organs.
What causes ovarian cancer?
The cause of ovarian cancer is not yet known. You have an increased risk of ovarian cancer if you:
- Have a family history of ovarian cancer
- Have never been pregnant
- Are over the age of 50, since the likelihood of developing ovarian cancer increases as you age
Studies show that women who have had children, who breastfeed, or who use oral contraceptives ( birth control pills) are less likely to develop ovarian cancer. These factors decrease the number of times a woman ovulates, and studies suggest that reducing the number of ovulations during a woman's lifetime may lower the risk of ovarian cancer, possibly because it reduces her overall exposure to oestrogen.
The menopause itself does not cause ovarian cancer, but studies have linked long term oestrogen replacement therapy (more than 10 years) to an increased risk of ovarian cancer. Women on oestrogen replacement therapy should discuss the risk and benefit of this treatment with their doctor.
What are the symptoms of ovarian cancer?
In its early stages, ovarian cancer has few symptoms. The first sign of ovarian cancer is usually an enlarged ovary. The ovaries are located deep within the pelvic cavity, so swelling may go unnoticed until it becomes more advanced.
Symptoms that may indicate ovarian cancer include:
- Persistent bloating/increased abdominal size
- Persistent pelvic and abdominal pain
- Loss of appetite and feeling full quickly
- Other possible symptoms include:
- Urinary symptoms
- Change in bowel habit
- Extreme fatigue
- Back pain
- Postmenopausal bleeding
- Rectal bleeding
How can I protect myself from ovarian cancer?
While there is no definitive way to prevent ovarian cancer, there are steps you can take to reduce your risk and detect the disease in its early stages, increasing your chances of survival.
- Report any irregular vaginal bleeding, bloating or abdominal pain to your doctor
- If you have close family members (mother, sister or daughter) with ovarian cancer, discuss your risk factors with your doctor
- Don’t use excessive talcum powder on or near the vagina; some research has linked talcum powder to an increased risk of ovarian cancer
- Maintain a healthy weight and don’t smoke
