Ovarian cancer

Diagnosis

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).
