Ovarian Cancer Diagnosis: Tests and What to Expect

Receiving a recommendation for further ovarian tests can be unsettling, especially when symptoms are persistent or an ultrasound has identified an unexpected pelvic mass. However, an abnormal finding does not automatically mean that cancer is present.

Ovarian cancer diagnosis involves a carefully planned process that may include medical history, pelvic examination, blood tests, ultrasound, and additional imaging. When cancer is suspected, tissue examination is generally needed to confirm the diagnosis and establish the type of tumour.

Understanding the purpose of each investigation can help patients prepare for appointments, interpret results appropriately, and know what to expect during the next stages of assessment.

How Does the Ovarian Cancer Diagnostic Process Begin?

The initial evaluation usually starts when a patient reports persistent symptoms or an abnormality is discovered during an examination performed for another reason.

Possible warning signs include abdominal bloating, pelvic discomfort, early satiety, urinary frequency, and changes in bowel habits.

These symptoms are not specific to ovarian cancer.

Many benign conditions, including ovarian cysts, endometriosis, and gastrointestinal disorders, can produce similar complaints.

The purpose of diagnostic testing is to identify the underlying cause and determine whether specialist investigation is required.

Medical History and Risk Assessment

A clinician typically asks about the nature and duration of symptoms, previous gynaecological conditions, menstrual history, menopausal status, and relevant medications.

Family history is particularly important.

Relatives with ovarian, breast, pancreatic, or certain colorectal cancers may raise questions about inherited cancer susceptibility.

The doctor may also ask about previous operations, fertility considerations, and existing medical conditions.

These details help guide the selection of diagnostic tests.

Physical Examination for Suspected Ovarian Cancer

A physical examination may include assessment of the abdomen and pelvis.

The clinician looks for tenderness, abdominal enlargement, an abnormal mass, or other findings that could explain the symptoms.

What Happens During a Pelvic Examination?

Depending on the patient’s circumstances, the doctor may recommend a pelvic examination to assess the reproductive organs.

The purpose of the examination should be explained beforehand, and the patient’s consent is essential.

A pelvic examination can identify certain abnormalities, but it cannot reliably detect or exclude ovarian cancer on its own.

Some ovarian masses may be too small or difficult to assess through physical examination.

Further investigations are often needed when symptoms or clinical findings remain concerning.

What Does Abdominal Fluid Mean?

Abnormal fluid accumulation in the abdominal cavity is called ascites.

Ascites can occur in advanced ovarian cancer, but it also has other possible causes, including liver disease and certain inflammatory conditions.

When unexplained ascites or a suspicious pelvic mass is identified, prompt specialist evaluation may be necessary.

The finding must be interpreted in the context of the patient’s overall medical condition.

Ultrasound: A Key Test in Ovarian Cancer Diagnosis

Pelvic ultrasound is one of the most important imaging methods used to investigate suspected ovarian abnormalities.

It uses sound waves to produce images of the ovaries, uterus, and surrounding pelvic structures.

Transvaginal Ultrasound

During a transvaginal ultrasound, a narrow ultrasound probe is inserted into the vagina with the patient’s consent.

This provides detailed images of the ovaries and nearby structures.

The examination can help identify cysts, solid masses, and other abnormalities.

A clinician may assess several characteristics, including the size of an ovarian lesion, whether it contains fluid or solid tissue, and whether it has internal partitions or other complex features.

Transvaginal ultrasound may cause some discomfort, but patients should be able to discuss concerns and request that the examination be stopped.

Transabdominal Ultrasound

A transabdominal ultrasound uses a probe placed on the lower abdomen.

It may provide a broader view of the pelvis and can be used alongside or instead of transvaginal imaging, depending on the clinical circumstances.

Sometimes patients are asked to have a full bladder to improve the examination.

The healthcare team should explain any preparation requirements before the appointment.

Can Ultrasound Confirm Ovarian Cancer?

Ultrasound can identify features that increase or decrease concern about malignancy.

However, it cannot always distinguish a benign ovarian mass from cancer with certainty.

A simple fluid-filled cyst may have a different risk profile from a complex mass containing solid components.

Specialists interpret these findings alongside age, menopausal status, symptoms, and blood test results.

CA-125 Blood Test: What Does It Tell Doctors?

CA-125 is a protein that may be present at increased levels in the blood of some patients with ovarian cancer.

It is commonly used as part of the evaluation of suspected epithelial ovarian malignancy.

Does an Elevated CA-125 Mean Cancer?

No. An elevated CA-125 result does not independently establish an ovarian cancer diagnosis.

Levels may also rise in benign conditions, including endometriosis, certain inflammatory disorders, and other medical problems.

Interpretation depends on the patient’s age, menopausal status, symptoms, and imaging findings.

An elevated result may lead to further investigation rather than an immediate diagnosis.

Can Ovarian Cancer Be Present With a Normal CA-125?

Yes. Some ovarian cancers do not produce a substantial increase in CA-125, particularly in certain early-stage cases or tumour subtypes.

A normal result therefore does not completely exclude malignancy.

Persistent symptoms or suspicious imaging findings may still require additional evaluation.

This limitation is one reason why CA-125 should not be considered a standalone cancer screening test.

Are the Same CA-125 Thresholds Used for Every Patient?

Not necessarily.

Clinical pathways may apply different thresholds or referral criteria according to age and other circumstances.

The updated NICE recommendations for suspected ovarian cancer include age-specific CA-125 thresholds for determining when urgent ultrasound is indicated in certain symptomatic patients.

A laboratory result should therefore be interpreted by the treating clinician rather than assessed through a single universal number.

Are Other Blood Tests Needed?

Additional laboratory investigations may be recommended depending on the patient’s symptoms, age, and imaging findings.

A complete blood count can help identify anaemia or other abnormalities.

Kidney and liver function tests may also provide information relevant to further investigation or treatment planning.

Other Tumour Markers

Certain ovarian tumours, particularly those occurring in younger patients, may require assessment with other markers.

Examples include alpha-fetoprotein (AFP), beta-human chorionic gonadotropin (beta-hCG), and lactate dehydrogenase (LDH) in selected clinical circumstances.

These tests may help clinicians investigate the possibility of particular tumour types.

However, no blood marker can independently establish the diagnosis of every ovarian malignancy.

The selection of tests should be based on the suspected condition rather than performed indiscriminately.

How Do Specialists Evaluate Whether an Ovarian Mass Is Suspicious?

Finding an ovarian cyst or mass does not mean that the patient has cancer.

Many ovarian cysts are benign, particularly before menopause.

The clinical challenge is to identify findings that require monitoring, further imaging, or specialist assessment.

Ultrasound Features and Risk Assessment

Specialists consider several ultrasound characteristics, including whether a lesion is predominantly cystic or solid, the appearance of internal structures, and findings such as ascites.

Standardised ultrasound assessment systems can help describe adnexal masses and estimate the likelihood of malignancy.

In some clinical pathways, a risk of malignancy index (RMI) combines ultrasound findings, menopausal status, and CA-125.

The choice of assessment method depends on local practice and the experience of the evaluating specialist.

Why Menopausal Status Matters

Ovarian masses are evaluated differently before and after menopause.

Benign functional cysts are common during reproductive years.

After menopause, a newly discovered or complex ovarian mass may require a different level of investigation.

However, menopausal status alone does not establish whether a mass is malignant.

The full clinical picture remains essential.

When Is a CT Scan Recommended?

Computed tomography (CT) may be recommended when ultrasound and other findings suggest ovarian cancer.

A CT scan can provide detailed images of the abdomen and pelvis and help assess possible disease beyond the ovaries.

What Can CT Imaging Reveal?

CT may help identify enlarged lymph nodes, abnormal abdominal tissue, ascites, and possible spread to other structures.

In selected cases, imaging of the chest may also be appropriate.

The information is useful for planning further investigations and determining whether specialist oncological assessment is required.

CT frequently involves intravenous contrast material.

The healthcare team should consider relevant allergies, kidney function, pregnancy status, and other factors when choosing an imaging protocol.

Is MRI Better Than CT for Ovarian Cancer?

MRI and CT answer different clinical questions.

MRI can be helpful when an ovarian lesion remains difficult to characterise after ultrasound.

It may provide additional detail about soft tissues and the internal structure of a complex mass.

CT is commonly used when clinicians need to assess the possible extent of suspected or confirmed cancer.

MRI is not required routinely for every patient with suspected ovarian cancer.

How Is Ovarian Cancer Confirmed?

Imaging and blood tests can suggest that an ovarian mass may be malignant.

However, definitive diagnosis generally requires examination of tissue or appropriate cellular material by a pathologist.

This examination identifies whether cancer cells are present and helps determine the tumour type.

Biopsy and Histological Examination

A biopsy involves obtaining a sample for laboratory examination.

In selected patients with suspected advanced ovarian cancer, an image-guided biopsy may be performed before starting chemotherapy.

The decision depends on the location of the suspected disease, the proposed treatment approach, and whether the procedure can be performed safely.

Not every ovarian mass should undergo a needle biopsy.

When a suspicious mass appears suitable for primary surgical removal, the team may plan an operation that provides tissue while managing the lesion appropriately.

Can Surgery Be Both Diagnostic and Therapeutic?

Yes.

In certain cases, surgery allows doctors to remove a suspicious ovarian mass and obtain tissue for definitive diagnosis.

If malignancy is confirmed, the operation may also contribute to staging or treatment, depending on the clinical circumstances and consent obtained.

The extent of surgery should be planned carefully, particularly when fertility preservation is relevant.

The most appropriate approach depends on the suspected tumour type, imaging findings, and the patient’s overall condition.

What Happens After Ovarian Cancer Is Confirmed?

Once the diagnosis has been established, the medical team determines the type and extent of disease.

This process is called staging.

Understanding Ovarian Cancer Stages

Ovarian cancer is generally described using four main stages.

Stage I refers to disease confined to the ovaries or fallopian tubes.

Stage II involves extension within the pelvis.

Stage III includes spread beyond the pelvis within the abdominal cavity or involvement of certain lymph nodes.

Stage IV refers to distant spread.

The precise stage depends on clinical, imaging, surgical, and pathological information, as appropriate.

The National Cancer Institute provides further details about ovarian cancer diagnosis, staging, and treatment.

Molecular and Genetic Testing

For certain ovarian cancer types, genetic and molecular testing can provide information relevant to treatment and inherited risk.

Tests may investigate BRCA1 and BRCA2 variants or other tumour characteristics.

Results can help determine eligibility for selected targeted therapies and whether family members may benefit from genetic counselling.

Not every ovarian tumour requires exactly the same testing.

Decisions should reflect the pathological diagnosis and current clinical recommendations.

Why Specialist Assessment Matters

A suspected ovarian cancer diagnosis can involve several professionals, including radiologists, pathologists, gynaecologic oncologists, and medical oncologists.

Multidisciplinary assessment can help ensure that diagnostic findings are interpreted together and that patients receive an appropriate treatment plan.

Dr. Georgios-Marios Makris is featured as a leading specialist in Iatromedia’s guide to the best gynaecologic oncologists in Greece. His professional experience includes specialist training in Germany and clinical practice in gynaecological oncology. The most suitable specialist for an individual patient depends on the diagnosis, treatment needs, and relevant expertise.

Can ovarian cancer be diagnosed with a blood test alone?

No. CA-125 and other blood markers can support diagnostic assessment, but they cannot independently confirm ovarian cancer. Clinical examination, imaging, and usually pathological evaluation are needed to establish an accurate diagnosis.

Is a transvaginal ultrasound painful?

A transvaginal ultrasound may cause some pressure or discomfort, but it is generally well tolerated. The clinician should explain the examination and obtain consent. Patients can discuss discomfort, anxiety, or alternatives before and during the procedure.

Does an abnormal ovarian ultrasound always mean cancer?

No. Many ovarian cysts and masses are benign. The significance of an abnormal finding depends on its ultrasound features, the patient’s age, symptoms, menopausal status, and other relevant results. Further assessment may be recommended when the appearance is suspicious or uncertain.

Is surgery always required to confirm ovarian cancer?

Not always. Tissue confirmation may be obtained through an image-guided biopsy in selected patients, particularly when advanced disease is suspected and chemotherapy is planned first. In other cases, surgery provides the tissue needed for diagnosis and may also serve as treatment. The approach must be individualised.

Conclusion

Ovarian cancer diagnosis is a step-by-step process that combines clinical assessment, laboratory investigations, imaging, and pathological examination.

Ultrasound and CA-125 can provide important information, but neither is sufficient to confirm or exclude the disease independently.

When findings raise concern, additional imaging and specialist evaluation help determine the appropriate next steps.

Accurate diagnosis supports individualised treatment planning and allows patients to understand their condition before important medical decisions are made.
