Ovarian cancer

Find out about the symptoms of ovarian cancer, how it's diagnosed and how it's treated.

Ovarian cancer, or cancer of the ovaries, is one of the most common types of cancer in women.

The ovaries are a pair of small organs located low in the tummy that are connected to the womb and store a woman's supply of eggs.

Ovarian cancer mainly affects women who have been through the menopause (usually over the age of 50), but it can sometimes affect younger women.

When to see your GP




Symptoms of ovarian cancer

Common symptoms of ovarian cancer include:

  • feeling constantly bloated
  • a swollen tummy
  • discomfort in your tummy or pelvic area
  • feeling full quickly when eating
  • needing to pee more often than normal

The symptoms aren't always easy to recognise because they're similar to those of some more common conditions, such as irritable bowel syndrome (IBS).

Read more about the symptoms of ovarian cancer.

When to see your GP

See your GP if:

  • you've been feeling bloated most days for the last three weeks
  • you have other symptoms of ovarian cancer that won't go away
  • you have a family history of ovarian cancer and are worried you may be at a higher risk of getting it

It's unlikely you have cancer, but it's best to check. Your GP can do some simple tests to see if you might have it. Read more about how ovarian cancer is diagnosed.

If you've already seen your GP and your symptoms continue or get worse, go back to them and explain this.

If you have a family history of ovarian cancer, your GP may refer you to a genetics specialist to discuss the option of genetic testing to check your ovarian cancer risk.

Causes of ovarian cancer

The exact cause of ovarian cancer is unknown.

But some things may increase a woman's risk of getting it, such as:

  • being over 50 years of age
  • a family history of ovarian or breast cancer – this could mean you've inherited genes that increase your cancer risk
  • hormone replacement therapy (HRT) – although any increase in cancer risk is likely to be very small
  • endometriosis – a condition where tissue that behaves like the lining of the womb is found outside the womb
  • being overweight

Read more about the causes of ovarian cancer.

Treatment for ovarian cancer

The treatment for ovarian cancer depends on things such as how far the cancer has spread and your general health.

The main treatments are:

  • surgery to remove as much of the cancer as possible – this will often involve removing both ovaries, the womb and the tubes connecting them to each other (fallopian tubes)
  • chemotherapy (where medicine is used to kill cancer cells) – this is usually used after surgery to kill any remaining cancer cells, but is occasionally used before surgery to shrink the cancer

Treatment will aim to cure the cancer whenever possible. If the cancer has spread too far to be cured, the aim is to relieve symptoms and control the cancer for as long as possible.

Read more about how ovarian cancer is treated and living with ovarian cancer.

Outlook for ovarian cancer

The earlier ovarian cancer is diagnosed and treated, the better the chance of a cure. But often it's not recognised until it has already spread and a cure isn't possible.

Even after successful treatment, there's a high chance the cancer will come back within the next few years.

If it does come back, it can't usually be cured. But chemotherapy may help reduce the symptoms and keep the cancer under control for several months or years.

Overall, around half of women with ovarian cancer will live for at least five years after diagnosis and about one in three will live at least 10 years.

Cancer Research UK has more information about the survival statistics for ovarian cancer.

Ovarian cancer

Find out about the main symptoms of ovarian cancer and when to get medical advice.

The symptoms of ovarian cancer can be difficult to recognise, particularly early on.

They're often the same as symptoms of less serious conditions, such as irritable bowel syndrome (IBS) or pre-menstrual syndrome (PMS).

Main symptoms

The most common symptoms of ovarian cancer are:

  • feeling constantly bloated
  • a swollen tummy
  • discomfort in your tummy or pelvic area
  • feeling full quickly when eating, or loss of appetite
  • needing to pee more often or more urgently than normal

Other symptoms

Other symptoms of ovarian cancer can include:

When to see your GP

See your GP if:

  • you've been feeling bloated most days for the last three weeks
  • you have other symptoms of ovarian cancer that won't go away – especially if you're over 50 or have a family history of ovarian or breast cancer, as you may be at a higher risk

It's unlikely you have cancer, but it's best to check. Your GP can do some simple tests for ovarian cancer to see if you might have it.

Ovarian cancer

Find out how ovarian cancer

Ovarian cancer occurs when cells in the ovaries grow and multiply uncontrollably, producing a lump of tissue called a tumour.

It's not clear exactly why this happens, but the following factors may increase your risk of getting ovarian cancer.

Increasing age

The risk of ovarian cancer increases as you get older, with most cases occurring after the menopause.

About 8 in every 10 cases are diagnosed in women over 50, although some rarer types of ovarian cancer can occur in younger women.

Family history and genes

You're more likely to get ovarian cancer if you have a history of it in your family, particularly if a close relative (sister or mother) has had it.

Sometimes this may be because you've inherited a faulty version of a gene called BRCA1 or BRCA2. These increase your risk of developing both ovarian and breast cancer.

But having relatives with ovarian cancer doesn't mean you definitely have a faulty gene. Only around 1 in every 10 ovarian cancers is thought to be caused by one of these genes.

Ovarian Cancer Action has a tool to help you check whether your family history puts you at risk of ovarian cancer.  

Speak to your GP if you're worried your family history may mean you're at a higher risk of ovarian cancer. They may refer you to see a genetic counsellor, who may suggest having a test to check for faulty genes.

Read more about genetic testing for cancer risk genes.

Hormone replacement therapy (HRT)

It has been suggested that taking hormone replacement therapy (HRT) may increase your risk of ovarian cancer. But studies looking at this have so far had conflicting results.

It's thought that if there is any increase in cases of ovarian cancer in women taking HRT, the risk is very small.

Any increased risk of ovarian cancer is thought to decrease after you stop taking HRT.


Research has shown that women with a condition called endometriosis may be more likely to develop ovarian cancer.

In endometriosis, the cells that usually line the womb grow elsewhere in the body, such as in the ovaries or tummy.

These cells still behave as if they were in the womb, including bleeding during periods. But as there's no way for the bleeding to leave the body, it becomes trapped and causes pain in the affected area.

Other factors

Other things that may increase your risk of ovarian cancer include:

  • being overweight or obese – losing weight through regular exercise and a healthy diet may help to lower your risk
  • smoking – stopping smoking may help reduce your risk of ovarian cancer and many other serious health problems
  • using talcum powder – some research has suggested that using talcum powder between your legs could increase your risk of ovarian cancer, but the evidence for this is inconsistent and any increase in risk is likely to be very small

Ovarian cancer

Find out about the tests used to diagnose ovarian cancer.

See your GP if you have symptoms of ovarian cancer. They can do some initial tests and you may also need further tests in hospital.

Seeing your GP

Your GP may:

  • ask about your symptoms and general health
  • gently feel your tummy to check for any swelling or lumps
  • carry out an internal examination
  • ask if there's a history of ovarian or breast cancer in your family
  • take a sample of blood – this will be sent to a laboratory and checked for a substance called CA125 (see below)

In some cases, you may be referred straight to a hospital specialist (usually a gynaecologist) for further tests without having a blood test.

Blood test (CA125 test)

If your GP thinks your symptoms could be due to ovarian cancer, they'll recommend having a blood test to check for a substance called CA125.

CA125 is produced by some ovarian cancer cells. A high level of CA125 in your blood could be a sign of ovarian cancer.

But a raised CA125 level doesn't mean you definitely have cancer, as it can also be caused by less serious things such as endometriosis, fibroids and even pregnancy.

If the test finds a high level of CA125, you'll be referred for a scan to check for possible causes (see below).

Sometimes your CA125 level can be normal in the early stages of ovarian cancer. If you've had a normal test result but your symptoms don't improve, go back to your GP as you may need to be re-tested.

Lab Tests Online UK has more information on the CA125 test.

Ultrasound scan

Your GP will arrange for you to have an ultrasound scan if your blood test suggests you could have ovarian cancer.

This is a type of scan where high-frequency sound waves are used to create an image of the inside of your body.

There are two ways it can be done:

  • abdominal ultrasound – a small device called an ultrasound probe is moved over your tummy to create an image of your ovaries
  • transvaginal ultrasound – an ultrasound probe is passed into your vagina to create a clearer image of your ovaries

The scan can show changes in your ovaries that could be caused by cancer or another problem such as endometriosis or a build-up of fluid.

If any abnormalities are found, you'll be referred to a specialist for further tests to confirm the cause (see below).

Further tests

The following tests may be carried out by a specialist in hospital to confirm or rule out ovarian cancer:

  • a CT scan – a type of scan where several X-rays are taken from different angles to create a detailed image of your ovaries
  • a chest X-ray to check if cancer has spread to your lungs
  • a needle biopsy – a needle is passed through your tummy to remove a sample of ovary cells or fluid from around the ovaries so it can be checked for cancer
  • a laparoscopy – a small cut is made in your tummy and a thin tube with a camera on the end is inserted, so your ovaries can be examined; a small tissue sample may also be removed for testing

If ovarian cancer is found, these tests can also help determine how far it has already spread.

Stages and grades of ovarian cancer

If you're diagnosed with ovarian cancer, it will be given a "stage".

This describes the size of the cancer and how far it has spread. It can help your doctors plan the best treatment for you.

The four main stages of ovarian cancer are:

  • stage 1 – the cancer only affects one or both of the ovaries
  • stage 2 – the cancer has spread from the ovary and into the pelvis or womb
  • stage 3 – the cancer has spread to the lining of the tummy, the surface of the bowel or the lymph glands in the pelvis or tummy
  • stage 4 – the cancer has spread to other parts of the body, such as the liver or lungs 

Your cancer will also be given a "grade". This is a way of describing how quickly the cancer is likely to grow or spread.

The grades range from grade 1 (more likely to grow slowly) to grade 3 (more likely to grow quickly).

Ovarian cancer

Find out about the main treatments for ovarian cancer, including surgery and chemotherapy.


Surgery is the main treatment for ovarian cancer. The aim is to remove all of the cancer or as much of it as possible.

Surgery usually involves removing:

  • both ovaries and the fallopian tubes
  • the womb (a hysterectomy)
  • a layer of fatty tissue in the tummy (the omentum)

If the cancer is just in one or both ovaries, you may only need to have the ovary or ovaries removed, leaving your womb intact. This means you may still be able to have children.

Surgery is carried out under general anaesthetic (where you're asleep). You'll probably only need to stay in hospital for a few days, but it may take many weeks to fully recover.

Read about living with ovarian cancer for more information on recovering from surgery.

Want to know more?


Chemotherapy is where medication is used to kill cancer cells. Most women with ovarian cancer have it in addition to surgery.

It may be used:

  • after surgery to kill any remaining cancer cells
  • before surgery to shrink the cancer and make it easier to remove
  • if ovarian cancer comes back after initial treatment.

Chemotherapy medicine is usually given as a drip into the vein, but is sometimes given as tablets. You'll need to come into hospital to receive the treatment, but can normally go home the same day.

Treatment is given in cycles, with a period of treatment followed by a period of rest to allow your body to recover. Most women have six cycles of chemotherapy, with each cycle lasting three weeks.

Chemotherapy can cause some unpleasant side effects, such as:

  • tiredness
  • feeling and being sick 
  • loss of appetite
  • hair loss 
  • diarrhoea
  • increased risk of infections

Most side effects can be controlled with medication from your doctor and they should pass once treatment stops. Read more about the side effects of chemotherapy.

Radiotherapy uses carefully directed beams of radiation to kill cancer cells.

It's not used very often to treat ovarian cancer, but may be used:

  • after surgery for early ovarian cancer, to kill any cancer cells left behind
  • to shrink tumours and reduce symptoms if ovarian cancer has spread and can't be cured

Common side effects of radiotherapy include sore skin, tiredness and hair loss in the treated area. These should pass after treatment stops.

Clinical trials

Research into newer and better treatments for ovarian cancer is ongoing through clinical trials.

Speak to your care team if you're interested in participating in a trial as part of your treatment. They can let you know about any research you may be able to get involved in.

It's important to be aware that you might not get an experimental treatment (you may be given a standard treatment that's being compared to the new one) and there's no guarantee that a new treatment will be more effective.

Ovarian cancer

Read about the issues that occur if you're being treated for ovarian cancer and advice to help you cope.

Recovering from surgery

Surgery to treat ovarian cancer is a major operation. It can take up to three months to fully recover.

You'll need to take things very easy for at least the first couple of weeks. Rest as much as possible and try to avoid spending too long on your feet.

You can start to gradually return to your normal activities in the following weeks, but be careful not to do too much too soon.

Your care team will let you know about anything you need to avoid while you recover. For example:

  • you'll probably need to take one to three months off work
  • you might not be able to drive for around a month
  • you may need to avoid strenuous lifting or heavy exercise for at least three months

A physiotherapist may help you come up with an exercise plan to help your recovery.

If both your ovaries have been removed and you haven't been through the menopause, you'll experience it after treatment.

Your doctor may suggest taking hormone replacement therapy (HRT) to control any menopausal symptoms at least until you reach the natural age for the menopause (between 45 and 55).

Follow up appointments

After your treatment has finished, you'll be invited for regular check-ups to see how you're doing.

These are usually every two to three months to begin with, but tend to become less frequent over time.

These appointments are a good chance to talk to your care team about any problems you're having or any questions you have.

It's quite common for ovarian cancer to come back within a few years of treatment finishing, so you may have regular blood tests and/or scans to check for this.

Tell your doctor as soon as possible if any of your symptoms return after treatment. Don't wait until your next appointment.

Help and support

Dealing with cancer can be a huge challenge for you and your friends and family, both practically and emotionally.

Talking to someone about your feelings or problems can help. 

It may help to:

  • talk to your care team or GP – they may be able to arrange professional support such as counselling or therapy
  • speak to your friends and family – be open about how you feel and what they can do to help; don't feel shy about telling them you need some time to yourself if that's what you want
  • get in touch with a support group or charity – many organisations have helplines, online forums, and local support groups where you can meet up with other people in a similar situation to you

Sex and fertility

Your sex life

Ovarian cancer can affect your sex life in several ways.

You'll probably be advised to avoid having sex for a few weeks after surgery so your wound has enough time to heal properly.

But even after your wound has healed, it's normal to not feel like having sex right away. It takes many women much longer to feel ready.

This may be because surgery has triggered the menopause, or it may just be a combination of the tiredness and the emotional stress associated with being diagnosed and treated for cancer.

Talk to your partner about how you feel and don't pressure yourself into having sex too soon. The "help and support" section above gives details of people and organisations to contact if you'd like to discuss the issue with someone.

Want to know more?

Fertility and pregnancy

For some women, treatment for ovarian cancer triggers an early menopause and means they're no longer able to have children.

Talk to your care team about this if it's a concern for you. It may be possible to have treatment that preserves your fertility if you still want to have children and the cancer hasn't spread to both ovaries.

If you do lose your fertility, it's normal to experience a sense of loss or grief. It can help to discuss your feelings with a partner, relative or close friend, or with your specialist nurse.

If your treatment involved chemotherapy and you're still able to have children, you'll usually be advised to avoid becoming pregnant for a couple of years in case the cancer comes back and you need further treatment.

Money and benefits

If you have to reduce your working hours or stop working due to your cancer, you may find it difficult to cope financially.

If you have cancer or you're caring for someone with cancer, you may be entitled to financial support. For example:

  • if you have a job but can't work because of your illness, you're entitled to statutory sick pay (SSP) from your employer 
  • if you don't have a job and can't work because of your illness, you may be entitled to employment and support allowance (ESA)
  • if you're caring for someone with cancer, you may be entitled to carer's allowance  
  • free prescriptions – you can apply for an exemption certificate that gives you free prescriptions for all medications for five years; speak to your GP or cancer specialist about this

It's a good idea to find out as soon as possible what help is available to you. You may want to ask to speak to the social worker at your hospital, who can give you the information you need.

If your cancer can't be cured

If nothing more can be done to treat your cancer, your care will focus on controlling your symptoms and helping you feel as comfortable as possible. This is called end of life or palliative care.

It also includes psychological, social and spiritual support for you and your family or carers.

Ovarian cancer

Lindy Waldron talks about coping with treatment for ovarian cancer and how it has affected her life.

"My problems started in 2003. I'd been having a difficult year, as both my father and brother died within three months of each other.

"I noticed my abdomen was expanding, even though I was eating less. I also had lower back pain and constipation. A lot of these symptoms at that time were attributed to stress because of my bereavement.

"I was initially diagnosed with irritable bowel syndrome. I had a colonoscopy, which was negative, then an ultrasound scan, which showed I had a large mass in my abdomen. My diagnosis was a complete shock.

"I had surgery to remove the mass, and all my 'female bits' removed. But unfortunately the cancer had spread to my spleen, and I had to have that removed as well. It was a big operation and I'm now on antibiotics for the rest of my life.

"I had six sessions of chemotherapy after surgery, which was quite aggressive. I was warned there would possibly be long-term side effects. I lost the feeling in my toes and my fingers. The feeling in my fingers has come back now, but my toes are still fairly numb.

"Apart from the sense of loss I had already suffered with my bereavements, there was also the loss of my job, identity, femininity and body image. Financially it's been difficult, as I had to give up my job. I'm only able to go back to part-time work.

"I feel fortunate that I'm still here after three years. I'm looking ahead, although I don't know what the long-term outlook will be. I try not to be neurotic, but it's easy to worry about anything that's unusual or different. If I have pain that's not normal for me, I always get it checked out.

"It's difficult to give advice. I think everyone's experience is different. Everyone has different ways of coping with things. My way was to try to keep busy, manically busy. I still try to cram as much into every day and week as possible.

"It's difficult to think long term, but it's important to just hold on to the fact that the treatment now is wonderful, the support you'll have is wonderful, and we don't know what's just around the corner.

"Sheer self-determination helped me get over it. In our family we just get on with things. We don't dwell on things and we keep busy. 'Mind over matter' is how I've been brought up and I think that really helped me.

"The most important thing is to try to not to be afraid. Don't feel stupid or that you're making a fuss about nothing. I think you know your own body and you know when something is different or unusual, so get it checked out."

Ovarian cancer

Read the story of Ruth Payne, who was diagnosed with ovarian cancer when she was 42.

Practice nurse Ruth Payne was diagnosed with ovarian cancer when she was 42.

"I went to my GP because I had a number of minor symptoms," says Ruth. "I had irritable bowel-type symptoms and went through a period of being very depressed, which I now think may have been related to the cancer. But I also had bloating, which is why I went to see the doctor. I looked seven months pregnant."

Ruth's GP thought she was pregnant. "She put me on the couch, held a sonicaid to my stomach and said, 'There's a very rapid heartbeat'. But then she realised it was my heartbeat."

Ruth was sent to her local hospital for a scan. "The radiographer took a long time. She'd obviously seen something that wasn't right." The results indicated a "suspicious lump". The next morning, the GP referred Ruth to the hospital.

At her first appointment with her consultant, he seemed fairly convinced that it was ovarian cancer. Various tests were organised to help them find out what the problem was. These included blood tests, a CT scan and a kidney function X-ray.

"As a nurse, I knew quite a lot about women's health issues, but I didn't know much about ovarian cancer," says Ruth. "It wasn't talked about much in the study days on women's cancers I attended. I just knew it as the 'silent killer'.

"By the time I was admitted for surgery, I was so large I could hardly walk. Whatever it was obviously needed removing. The day before surgery, one of the scans suggested that there could be a problem with my liver, which meant having a liver scan done just before my operation. Fortunately, the scan revealed no problem."

During the surgery, doctors performed a frozen section biopsy to give them some idea of whether Ruth had cancer. This type of biopsy isn't always possible and it isn't 100% reliable. In Ruth's case, however, results showed that it was cancer. The ovaries were removed and a hysterectomy was carried out, and other tissues were sampled to check that the cancer hadn't spread to other parts of her body.

Ruth says, "The oncologist came to see me several days later. He said that although the cancer was at an early stage, I needed chemotherapy as well, because it was an aggressive tumour. He gave me the option of having standard chemotherapy, or participating in a trial of another kind of chemotherapy as well. I decided to go for the standard treatment."

The doctor told Ruth the worst side effect she would feel from the chemotherapy was tiredness. "I don't think 'tired' is quite the word!" she says. "I know it varies from person to person, but some days I felt like I'd been poleaxed. I even found it difficult to walk."

Ruth also cut her hours as a practice nurse, as she was concerned about picking up an infection. She had six cycles of chemotherapy, one every three weeks. Her chemotherapy treatment lasted for 18 weeks.

After the chemotherapy, Ruth didn't need any more treatment. She's still cancer-free, although she has only just been discharged. It took Ruth a long time to recover fully from the chemotherapy. "I got tired very easily and I was infected by any bug going around. For a long time it was easy to think that any ache or pain was the cancer returning, but this gradually lessened as time went on."

She advises women diagnosed with ovarian cancer to take things one day at a time. "It's natural to want to know what's going to happen in a year's time. But if you think about all the things that might happen, you can't cope. Make the most of your friends. If they offer help, give them specific things to do, like taking you to hospital, cooking meals when you might be feeling sick, collecting the children from school, and just being there if you need to talk.

"Don't be surprised if you don't feel on top of the world when you get to the end of treatment: it can often feel like an anti-climax. After all the medical attention you have received, you might feel very vulnerable without all the checks you've had at the hospital. It's sometimes at this stage that the enormity of all that's happened suddenly hits you.

"You might find it helpful to speak to others who've been in a similar position. Ask if there are any support groups, but this might not be for everyone. Be careful about searching on the internet, as there can be a lot of information, which can be quite overwhelming and a bit scary. It sometimes helps if you can get a friend to look for you. Some information may be out-of-date and it won't all apply to you."
