Ovarian Cancer: The Silent Killer

Ovarian cancer is a type of cancer that begins in or around the ovaries, the reproductive organs that produce eggs and hormones. It can be difficult to detect in its early stages because the symptoms may be mild, vague or mistaken for common digestive, urinary or menstrual problems.

Bloating, feeling full quickly, pelvic discomfort, changes in bowel habits and frequent urination may not seem alarming on their own. The important thing is to pay attention when these symptoms are new, persistent, becoming more frequent or happening together.

Ovarian cancer is more common as women get older, particularly after menopause. However, it can occur at any age, and younger women can also develop certain less common types of ovarian cancer. Current SEER data show that the median age at diagnosis is about 63 years.

Understanding the warning signs and knowing when to seek medical advice can make a real difference.

What is ovarian cancer?

Ovarian cancer develops when cells in or around the ovary acquire abnormal changes that cause them to grow and multiply uncontrollably. These abnormal cells can form a tumour and may eventually invade nearby tissues or spread to other parts of the body.

There are different types of ovarian cancer. Epithelial ovarian cancer is the most common, while germ cell and stromal tumours are less common and tend to occur in different age groups. Some cancers traditionally called ovarian cancer may actually originate in the fallopian tubes or nearby tissues but are treated in a similar way.

What are the early warning signs of ovarian cancer?

One of the challenges with ovarian cancer is that there may be no obvious early warning sign. When symptoms do occur, they can resemble much more common conditions.

Some early warning signs to watch for include:

• Persistent abdominal bloating or swelling
• Pelvic or lower abdominal discomfort
• Feeling full after eating only a small amount
• Reduced appetite
• Unexplained weight loss
• Changes in bowel habits, including constipation
• Needing to urinate more frequently or urgently
• Persistent tiredness
• Back pain

Having one of these symptoms does not mean that you have ovarian cancer. Conditions such as irritable bowel syndrome, ovarian cysts, urinary infections, fibroids and digestive disorders can cause similar symptoms.

What matters is the pattern. Symptoms that are new, persistent or progressively getting worse deserve medical evaluation.

What are 6 signs of ovarian cancer?

Six commonly recognised signs are:

1. Persistent bloating or abdominal swelling
2. Pelvic or abdominal pain or pressure
3. Feeling full quickly when eating
4. Changes in bowel habits
5. Frequent or urgent urination
6. Unexplained weight loss or loss of appetite

Fatigue and back pain can also occur.

The key is not simply having one symptom once. Persistent or recurring symptoms that are unusual for you should be discussed with a doctor.

What are the symptoms of stage 1 ovarian cancer?

Stage 1 ovarian cancer means the cancer is confined to one or both ovaries or fallopian tubes, depending on the exact stage classification.

Stage IA involves one ovary or fallopian tube, while stage IB involves both.

Stage IC includes additional features such as tumour rupture, cancer on the surface or cancer cells in abdominal fluid.

Some women with stage 1 ovarian cancer have no symptoms at all. Others may experience mild symptoms such as:

• Bloating
• Pelvic discomfort
• Abdominal pressure
• Feeling full quickly
• Changes in bowel or bladder habits
• Fatigue

This is why it is not possible to determine the stage of ovarian cancer simply from symptoms.

Stage 1 is generally considered early ovarian cancer, and outcomes are usually much better when cancer is detected while it remains localised. SEER data report a 5-year relative survival of about 91.9% for localised ovarian cancer, although survival statistics cannot predict what will happen to an individual person.

What is the biggest indicator of ovarian cancer?

There is no single symptom or test that can be called the biggest indicator of ovarian cancer.

Persistent and unexplained abdominal bloating, particularly when accompanied by pelvic discomfort, early fullness or urinary and bowel changes, is one of the patterns that should not be ignored.

However, symptoms alone cannot diagnose ovarian cancer. A doctor may need to combine your medical history, pelvic examination, imaging and blood tests, and sometimes tissue examination, to establish the diagnosis.

What age does ovarian cancer usually start?

Ovarian cancer becomes more common with increasing age. It is relatively uncommon before age 40, and most cases occur after menopause.

Current US SEER statistics show that ovarian cancer is most frequently diagnosed between ages 55 and 74, with a median age at diagnosis of approximately 63 years.

That does not mean younger women are completely protected. Germ cell ovarian tumours, for example, tend to occur at younger ages. The type of ovarian cancer therefore matters when considering age.

Women with certain inherited genetic mutations, such as BRCA1 or BRCA2, may have a higher risk and can develop ovarian cancer at younger ages than the general population.

How to test for ovarian cancer?

There is no single routine test that can definitively diagnose ovarian cancer.

If ovarian cancer is suspected, a doctor may recommend several investigations, including:

Pelvic examination

A pelvic examination allows the doctor to assess the reproductive organs and look for abnormalities such as an enlarged ovary or pelvic mass.

Ultrasound

A pelvic ultrasound, particularly a transvaginal ultrasound, can provide detailed images of the ovaries and help identify cysts, masses or other abnormalities.

Blood tests

The CA-125 blood test is commonly associated with ovarian cancer. CA-125 is a tumour marker that can be elevated in many women with ovarian cancer.

However, CA-125 is not a standalone diagnostic test. It can also rise because of non-cancerous conditions such as endometriosis, menstruation, pelvic inflammation and some other diseases. Conversely, some women with ovarian cancer may have a normal CA-125 level.

CT or other imaging

CT scans may be used to evaluate the abdomen and pelvis and determine whether a suspicious tumour has spread.

Biopsy or surgery

A definitive diagnosis may require examination of tumour tissue by a pathologist. In many cases, tissue is obtained during surgery.

The exact combination of tests depends on the person’s symptoms, examination findings, age, risk factors and imaging results.

Can ovarian cancer be seen on an ultrasound?

Yes, ovarian cancer may be visible on an ultrasound, particularly when it produces a suspicious ovarian mass or changes in the surrounding tissues.

Ultrasound can help doctors assess the size, shape and structure of the ovaries and identify features that may require further investigation.

However, an ultrasound cannot always tell whether a mass is definitely cancerous. Many ovarian cysts and masses are benign.

A suspicious ultrasound finding may therefore lead to additional tests, such as CA-125 testing, CT imaging, specialist assessment or surgery.

It is also important to understand that a normal ultrasound does not necessarily rule out every case of ovarian cancer, particularly when symptoms persist.

What blood test is used to diagnose ovarian cancer?

The blood test most commonly associated with ovarian cancer is CA-125.

CA-125 measures the level of a protein that can be elevated in some women with ovarian cancer. However, it is not accurate enough to be used alone to diagnose ovarian cancer or as a general screening test for women at average risk.

Doctors interpret CA-125 alongside symptoms, examination findings and imaging. Other tumour markers may sometimes be used depending on the suspected type of ovarian tumour.

What is the biggest cause of ovarian cancer?

There is no single biggest cause of ovarian cancer.

Ovarian cancer develops because cells acquire genetic changes that allow them to grow abnormally. Doctors do not know exactly why these changes occur in every woman.

Several factors can increase risk, including:

• Increasing age
• Family history of ovarian cancer
• Inherited BRCA1 or BRCA2 mutations
• Lynch syndrome and other inherited conditions
• Endometriosis
• Never having been pregnant
• Certain reproductive factors
• Postmenopausal hormone therapy
• Obesity

Having a risk factor does not mean that a woman will definitely develop ovarian cancer. Likewise, ovarian cancer can occur in women who have none of the recognised risk factors.

How long can a woman have ovarian cancer without knowing?

There is no fixed period.

Some women may have ovarian cancer for a considerable period before diagnosis because early disease can cause few or nonspecific symptoms. Ovarian cancer symptoms may initially resemble digestive problems, hormonal changes or urinary issues.

This is one reason ovarian cancer is sometimes diagnosed at a more advanced stage. It does not mean that every case progresses silently for a specific number of months or years.

If symptoms such as bloating, abdominal discomfort, early fullness or urinary changes persist or repeatedly return, it is better to have them assessed rather than assuming they are simply digestive or age-related.

What are some silent symptoms of ovarian cancer?

“Silent symptoms” generally refers to subtle symptoms that may be easy to dismiss.

These can include:

• Mild but persistent bloating
• Feeling full unusually quickly
• A gradual increase in abdominal size
• Mild pelvic pressure
• Frequent urination
• Changes in bowel movements
• Unexplained tiredness
• Subtle loss of appetite
• Unexplained weight loss

None of these symptoms is specific to ovarian cancer. Their significance comes from their persistence, recurrence or combination with other symptoms.

Is ovarian cancer treatable?

Yes, ovarian cancer is treatable. The treatment depends on the type of tumour, its stage, whether it has spread, the person’s overall health and the tumour’s genetic and molecular characteristics.

Treatment commonly includes:

Surgery

Surgery may remove the cancer and affected reproductive organs. In selected early-stage cases, surgery may be limited to the affected ovary and fallopian tube, particularly when fertility preservation is important.

More extensive disease may require removal of both ovaries and fallopian tubes, the uterus and other affected tissues.

Chemotherapy

Chemotherapy is frequently used after surgery and may also be given before surgery in certain situations. Its purpose is to destroy cancer cells and reduce the risk of remaining disease.

Targeted therapy

Some ovarian cancers have specific genetic or molecular characteristics that make them suitable for targeted medicines. PARP inhibitors, for example, may be used in selected patients.

Other treatments

Depending on the individual case, doctors may consider other systemic therapies, maintenance treatment or participation in clinical trials.

Ovarian cancer can sometimes be successfully treated, particularly when detected early. Even when it cannot be completely cured, treatment may control the disease, reduce symptoms and help a person live longer.

What are the signs and symptoms of recurring ovarian cancer?

Ovarian cancer can return after treatment. This is known as recurrence.

Symptoms of recurrent ovarian cancer can resemble those experienced during the original illness, including:

• Persistent bloating or abdominal swelling
• Pelvic or abdominal pain
• Feeling full quickly
• Loss of appetite
• Unexplained weight loss
• Changes in bowel habits
• Constipation
• Frequent or urgent urination
• Fatigue
• Back pain
• Increasing abdominal fluid or swelling

Some recurrences may initially produce very few symptoms. Follow-up appointments are therefore important after treatment. Doctors may use examinations, imaging, CA-125 levels and other investigations depending on the original cancer and treatment history.

How long does ovarian cancer take to go from stage 1 to 4?

There is no predictable timeline for ovarian cancer to progress from stage 1 to stage 4.

Cancer does not progress at the same speed in every person. Different ovarian cancer types and subtypes behave differently. Some tumours are more aggressive, while others grow more slowly.

Stage 4 means the cancer has spread beyond the abdominal region to distant areas of the body. Stage 1, by comparison, is confined to one or both ovaries or fallopian tubes.

Because progression is unpredictable, doctors cannot say that ovarian cancer will take a certain number of months or years to move from stage 1 to stage 4.

The most important message is that earlier diagnosis provides a better opportunity for effective treatment.

How to avoid ovarian cancer?

There is no guaranteed way to prevent ovarian cancer. However, some measures can reduce risk or help identify women who may benefit from closer medical assessment.

Discuss your family history with your doctor, particularly if close relatives have had ovarian, breast or certain colorectal cancers.

Women with a strong family history may be offered genetic counselling and testing for inherited mutations such as BRCA1 and BRCA2.

Some factors associated with lower ovarian cancer risk include pregnancy and use of oral contraceptives. However, birth control pills also have potential risks, so they should not be started solely for cancer prevention without discussing the benefits and risks with a healthcare professional.

For women at very high inherited risk, risk-reducing surgery may sometimes be considered.

Importantly, there is currently no universally recommended routine screening test for ovarian cancer in women at average risk. Ultrasound and CA-125 testing may be considered in certain high-risk situations, but they have not been shown to provide an effective general screening strategy.

When should you see a doctor?

Do not panic if you experience bloating or abdominal discomfort once in a while. These symptoms are extremely common and are usually caused by something other than cancer.

However, speak to a doctor if symptoms are:

• New and unexplained
• Persistent
• Becoming more frequent
• Getting progressively worse
• Occurring together
• Associated with unexplained weight loss or loss of appetite
• Accompanied by a pelvic or abdominal mass

A medical evaluation does not necessarily mean cancer is suspected. It simply helps identify the actual cause and ensures that potentially important conditions are not overlooked.

Frequently asked questions about ovarian cancer

What are the earliest symptoms of ovarian cancer?

Early symptoms can include persistent bloating, pelvic or abdominal discomfort, feeling full quickly, urinary frequency, bowel changes and unexplained fatigue. Early ovarian cancer may also cause no noticeable symptoms.

Is ovarian cancer always fatal?

No. Ovarian cancer is not always fatal. Prognosis depends heavily on the stage, tumour type, grade, overall health and response to treatment. Localised ovarian cancer has substantially better survival than cancer diagnosed after it has spread.

Can ovarian cancer be cured?

Some ovarian cancers, particularly those detected early, can be treated successfully and may be cured. Advanced ovarian cancer can also respond to treatment, although it may require long-term management and can recur.

Does a normal CA-125 mean I don’t have ovarian cancer?

No. A normal CA-125 does not completely rule out ovarian cancer. CA-125 is only one part of the diagnostic process.

Does an ovarian cyst mean cancer?

Usually not. Many ovarian cysts are benign. However, the appearance, size, persistence and other characteristics of a cyst determine whether further evaluation is needed.

Can ovarian cancer be detected through a routine ultrasound?

An ultrasound can identify suspicious ovarian abnormalities, but it cannot by itself confirm or exclude ovarian cancer in every situation. Further testing may be necessary.

Is bloating always a symptom of ovarian cancer?

No. Bloating is much more commonly caused by digestive or other non-cancerous conditions. Persistent or unusual bloating, especially when accompanied by other ovarian cancer symptoms, should be assessed.

Who is at higher risk of ovarian cancer?

Risk increases with age and may be higher in women with a strong family history, BRCA1 or BRCA2 mutations, Lynch syndrome, endometriosis and certain reproductive or hormonal factors.

The bottom line

Ovarian cancer can be difficult to recognise because its early symptoms are often subtle and can look like ordinary digestive or urinary problems. There is no single “biggest” symptom, blood test or ultrasound finding that confirms ovarian cancer.

Persistent bloating, pelvic or abdominal discomfort, feeling full quickly, bowel or urinary changes and unexplained weight loss deserve attention when they are new or do not go away.

Ultrasound and CA-125 testing can be important parts of an evaluation, but neither test alone can diagnose ovarian cancer. Diagnosis usually requires a combination of clinical assessment, imaging, blood tests and, when appropriate, examination of tumour tissue.

Most importantly, ovarian cancer is treatable, and early detection can significantly improve the chances of successful treatment. If you have persistent or unexplained symptoms, speak with a gynaecologist or other qualified healthcare professional rather than waiting for them to become severe.
