Understanding Ovarian Cancer Screening in the UK

Ovarian cancer is one of the leading causes of cancer-related deaths among women, highlighting the importance of timely detection and intervention. In the United Kingdom, various screening options are available, both through the National Health Service (NHS) and for private patients. This blog aims to provide an overview of ovarian cancer screening services in the UK so that individuals can make informed decisions about their health.

Ovarian Cancer: Understanding the Risks

Before delving into screening options, it is crucial to understand the risk factors associated with ovarian cancer. While the exact causes remain unclear, certain factors can increase the likelihood of developing the disease:

  1. Age: The risk of ovarian cancer increases with age, particularly after menopause.
  2. Genetics: Approximately 10-15% of ovarian cancers are linked to inherited gene mutations, such as BRCA1 and BRCA2.
  3. Family History: Having a first-degree relative (mother, sister, daughter) with ovarian cancer may increase the risk.
  4. Reproductive History: Women who have never been pregnant, started menstruation early or experienced menopause late, have a higher risk.
  5. Hormone Replacement Therapy (HRT): Long-term use of estrogen-only HRT may slightly increase ovarian cancer risk.

NHS Ovarian Cancer Screening Services

The NHS in the UK offers various screening methods for early ovarian cancer detection. It’s important to note that regular screening is not offered to all women. Instead, it is primarily recommended for those who are at higher risk based on family history or gene mutations, or for those showing potential symptoms.

The main screening options through the NHS include:

  1. Transvaginal Ultrasound (TVU): This procedure uses high-frequency sound waves to create images of the ovaries. It can help identify any abnormal growths or cysts that may require further investigation.
  2. CA-125 Blood Test: CA-125 is a protein marker that may be elevated in cases of ovarian cancer. This blood test may help identify changes in CA-125 levels, although it may not be specific to ovarian cancer alone.

In some cases, the NHS may also consider a referral to a specialist for further assessment or offer genetic testing if there is a strong family history of ovarian cancer.

Private Ovarian Cancer Screening Services

For individuals who prefer private healthcare, there are options available outside of the NHS. Private ovarian cancer screening services often provide additional screening methods or variations of existing tests, which may include:

  1. Risk Assessment: Private providers typically offer detailed risk assessment questionnaires to identify individuals who may benefit from screening based on personal and family history.
  2. CA-125 with Risk Stratification: In addition to measuring CA-125 levels, private tests may employ algorithms that consider factors such as age, BMI, and menopausal status to provide an individualized risk assessment.
  3. Pelvic Ultrasound: Private clinics may utilize more advanced technologies, including 3D/4D ultrasound, to obtain detailed images of the pelvic region for improved visualization of the ovaries.
  4. MRI Scans: Magnetic Resonance Imaging (MRI) scans are highly detailed and can provide a more comprehensive assessment of the pelvic region.

It’s important to consider that private screening services are not regulated by the NHS, so individuals should carefully research and choose reputable providers.


Ovarian cancer screening plays a crucial role in the early detection and effective treatment of the disease. In the UK, the NHS provides screening services primarily to individuals at higher risk or with symptoms. Routine screening for the general population is currently not recommended. Private healthcare options offer a range of additional screening techniques that may provide more detailed assessments.

Remember, if you have concerns about ovarian cancer or if you fall into a higher-risk category, consult with your GP or a gynecologist to discuss the best course of action. Early detection can significantly improve the prognosis and treatment options, making ovarian cancer screening an essential aspect of women’s health.
