What symptoms need to be investigated for ovarian cancer?

Adapted from Top Tips for Primary Care. Dr Victoria Barber scrutinises the role of primary care in the identification of Ovarian Cancer, an often overlooked malignancy. August 21 2023.

Ovarian cancer is often considered difficult to diagnose, particularly in the early stages, so women need to be aware of when they should visit their General Practitioner and what symptoms may occur.

The symptoms of ovarian cancer can occur with many other conditions too, and this can lead them to being overlooked by both patient and doctor. Yet, there are a group of symptoms that need attention. Ovarian cancer occurs more often in women older than the age of 50, but does occur in young women too.

The symptoms to look out for are: pelvic or abdominal pain, persistent abdominal distention also referred to as bloating, feeling full after very small meals or loss of appetite, and urinary urgency or frequency that is unusual for that woman. Frequent is considered to be more than 12 times in a month or 2 to 3 times a week. Persistent means beyond the time that you would expect a simple cause of a symptom to resolve.

Other symptoms of cancer in general are unexplained changes in bowel habit, unexplained weight loss, and unexplained fatigue. Ovarian, other bowel or pancreatic cancers, leukaemia, lung, and urological cancers can cause these. Further history and examination will help clarify the likely source of the problem and useful investigative tests and referrals.

If these symptoms are reported to the GP, the GP is best to examine the patient and also to take a blood test called the CA125. Next steps will depend on that blood level. Levels over 35 will usually indicate referral for an urgent ultra sound scan of the pelvis. If the scan is abnormal, an urgent “cancer suspected” appointment to gynaecology should be obtained. This is usually within two weeks in the NHS.

If the symptoms are not thought to be of a potentially serious nature or if a CA125 is not done, it can be helpful to arrange a review appointment for when the GP would expect resolution of the symptoms experienced. This is so that persistent symptoms are not missed.

Breast and ovarian cancer tend to run in families and genetic testing may be indicated in some patients.

Sometimes the urinary symptoms sound like a urinary infection but the dipstix test or bacteriological test will be negative. This can be a situation that calls for a CA125 tests for clarification.

Irritable bowel syndrome should not be considered as a new diagnosis in people over the age of 50. It is more likely to be something more serious such as bowel cancer, ovarian cancer, coeliac disease or colitis.

In young women, under the age of 50, bloating of the abdomen related to irritable bowel syndrome tends to come and go throughout the day, be related to meals or stress, and usually improves with having a bowel movement. In ovarian cancer, the bloating tends to last all day, can be there on waking, and is usually unaffected by passing a bowel movement.
