Testing

Find out about the tests that are used to diagnose ovarian cancer.

If you're experiencing the symptoms of ovarian cancer more than 12 times a month, your GP should do a CA125 blood test. A small sample of blood will be taken from your arm and sent to a lab where they will measure the level of a protein called CA125 in your sample.

Depending on the results of this blood test, your GP may recommend an ultrasound of your tummy and ovaries. An ultrasound scan creates a picture of the tissues and organs inside your body. If the results of the tests suggest ovarian cancer might be a possibility, you'll be referred to see a specialist called a gynaecological oncologist for further tests.
