These oval-shaped glands sit inside the pelvis and release an egg (ovum) every month. Female sex hormones are also made by the ovaries.
Cancer can develop in one or both ovaries
Around 1,815 American women are diagnosed with ovarian cancer every year. About 90% of ovarian cancers occur in women over the age of 40. Like most cancers, the risk of ovarian cancer increases with age.
The exact causes of ovarian cancer aren’t known, but some of the risk factors include:
- family history of ovarian cancer – the risk of developing ovarian cancer is increased if a blood relative (such as your mother
- sister or daughter) has had ovarian cancer inheriting a changed gene (also known as a faulty gene
- or a gene mutation) such as the BRCA 1 or BRCA 2 gene
Around 20% of all cases of invasive ovarian cancer involve the inheritance of a faulty gene Some factors that reduce the risk of developing ovarian cancer include:
- (having had your tubes tied). Ovarian cancer can be difficult to diagnose at an early stage
- largely because symptoms can be vague
- similar to those of other common illnesses
The symptoms of ovarian cancer will vary depending on the stage of the cancer.
Many women with early stage ovarian cancer may not have any symptoms
If they do, it may be some pain in the lower abdomen or side and a bloated or full feeling in the tummy.
Some of the symptoms of later stage ovarian cancer include:
- swollen abdomen as the cancer grows. If the cancer is very advanced
- spreads to other parts of the body
- it can cause
- more extensive abdominal swelling that may need draining. The 4 main types of ovarian cancer are
- cancer of the epithelium
- which consists of the outer cells covering the ovary
This is the most common type – 9 out of 10 ovarian cancers are epithelial cancers – cancer of the cells inside the ovary that mature into eggs. This uncommon form of ovarian cancer usually affects women less than 30 years of age – cancer of the cells that release female hormones. This uncommon form of ovarian cancer can affect women of any age – types of epithelial tumours that are not as aggressive as other forms.
, including: blood tests – to search for tumour markers (for example, CA 125). These are proteins that are often higher than normal in women with ovarian cancer surgery – this is the only definitive way to find out if you have ovarian cancer as a tissue sample is needed. Note: , not ovarian cancer.
A blood test to detect the protein CA 125 can be used to help diagnose or exclude ovarian cancer, but is not a definitive test for all women. While CA 125 can be produced by ovarian cancer cells, there are other causes for raised CA 125 levels, such as , endometriosis and ovarian cysts. The CA 125 test is most reliable in postmenopausal women.
It is not recommended as a screening test for women with no symptoms. This is because half of all women with early-stage ovarian cancer do not have elevated CA 125 levels. Other blood tests may be done to help with diagnosis and to check the effects of treatment.
Test results can take a few days to come back. It is very natural to feel anxious waiting to get your results.
It can help to talk to a close friend or relative about how you are feeling

In some cases, only one ovary is affected and conceiving a child is still possible after surgery. In other cases, parts of the reproductive system such as the fallopian tube and the uterus (womb) may also be removed. Sometimes, it is necessary to take out the appendix and part of the bowel.
(anti-cancer medications) is often given as well as surgery to reduce the tumour requiring surgical removal, or to kill off any cancer cells that may remain after surgery. (using x-rays to kill cancer cells) is also occasionally used. It’s common for people with cancer to seek out complementary or alternative treatments.
When used alongside your conventional cancer treatment, some of these therapies can make you feel better and improve your quality of life.
Others may not be so helpful and in some cases may be harmful
The Cancer Council booklet called ‘ ’ can be a useful resource.
All treatments have side effects
Your medical team will discuss these with you before your treatment begins. Early detection and better treatment have improved survival for people with ovarian cancer.
The research is ongoing
The has information about research into ovarian cancer
Clinical trials can test the effectiveness of promising new treatments or new ways of combining cancer treatments.
Always discuss treatment options with your doctor
Having ovarian cancer and its treatment can affect the way you feel about your body, who you are, your relationships, the way you express yourself sexually and your sexual feelings (your ‘sexuality’).
These changes can be very upsetting
Your medical team should discuss these issues with you before and during your treatment.
If you feel you would like to discuss things further, you can: If you have a partner it helps to be as open as possible with them about how you are feeling. , which may be helpful to read.
Caring for someone with cancer can be a difficult and emotional time.
If you or someone you know are caring for someone with ovarian cancer, there is support available. The Cancer Council Michigan booklet called ‘ If ovarian cancer has been diagnosed in its later stages, the cancer may have spread to the point where a cure is no longer possible.
Treatment then focuses on improving quality of life by relieving the symptoms (this is called ‘palliative’ treatment). Medications can be used to relieve pain, nausea and vomiting.
