The test involves screening for the tumour marker CA-125. The CA-125 Blood Test is a blood test that measures the level of CA-125, a protein that is produced by cells in the body and can be elevated in certain cancers, particularly ovarian cancer. This test is used to monitor the progression of ovarian cancer in patients who have been diagnosed with the disease, as well as to screen for ovarian cancer in high-risk populations. The CA-125 Blood Test can also be used to monitor response to treatment and detect recurrence of ovarian cancer. This test is ideal for individuals with a family history of ovarian cancer or other risk factors for the disease. The CA-125 Blood Test provides valuable information about cancer status, enabling individuals to take proactive steps to protect their health and manage their disease.

Screening for Ovarian Cancer is done by doing a CA-125 blood test which can be done by a home test kit. It can also be done by booking an in-clinic appointment.

What is the role of CA-125 in Ovarian Cancer?

CA-125 is made by cells in the female reproductive system, and by other cells in the body, and elevated levels of this protein can be a sign of certain medical conditions.

The CA-125 blood test is most commonly used to monitor the progression of ovarian cancer, as elevated levels of CA-125 can be an indicator of the disease or its recurrence. The presence of  high levels of CA-125 can be caused by other conditions, like endometriosis, uterine fibroids, and pelvic inflammatory disease. This makes the CA-125 blood test an important tool for diagnosing and monitoring a variety of medical conditions.

Who should consider the CA-125 blood test?

The CA-125 blood test may be recommended by your healthcare provider if you are experiencing symptoms of ovarian cancer.  Additionally, these symptoms include abdominal bloating, feeling full quickly while eating, fatigue and weight loss.

What are the Risk Factors for Ovarian Cancer?

  • Family history of ovarian cancer — about 3% of cases occur in women with a family history
  • Family history of other cancers
