Ovarian Cancer Symptoms: 7 Warning Signs That Are Often Overlooked

When ovarian cancer is detected before it spreads beyond the ovaries, survival chance is high. But diagnosis can be delayed since early signs may not be obvious. Most of the time, these symptoms are not caused by cancer — but waiting to find out isn’t the safest option.

According to the American Cancer Society, the 5-year relative survival rate for early stage ovarian cancer is at least 90%.

The National Ovarian Cancer Coalition reports that 1 in 78 females will be diagnosed with ovarian cancer in their lifetime.

However, 4 out of 5 people with this cancer are not diagnosedin the early stages because the signs of ovarian cancer can be easy to miss.

So, what are the silent signals of ovarian cancer? Let’s look at what’s known about these often overlooked symptoms.

Why does ovarian cancer often go undetected?

In its early stages, ovarian cancer may not present any noticeable signs.

When symptoms appear, they are often the kinds you normally associate with more common conditions like irritable bowel syndrome and urinary tract infections.

For many people, this means that ovarian cancer isn’t detected until it has spread. This, ultimately, can lower the survival rate for this type of cancer.

What are the so-called silent symptoms of ovarian cancer?

As already mentioned, many early signs of ovarian cancer overlap with symptoms of other common conditions.

However, you are the expert on your body. Trust your intuition if something feels wrong or different, and follow up with your doctor or healthcare professional as soon as possible.

Let’s take a closer look at 7 silent warning signs of ovarian cancer that are often ignored or overlooked.

1. Bloating

It’s typical to feel bloated around your menstrual period or when you’ve eaten certain foods. But bloating that doesn’t go away is a common symptom of ovarian cancer.

Around 72% of those with ovarian cancer say they experienced bloating. Here’s how some people describe the bloating:

  • It feels as though you’re pregnant.
  • It makes your clothes dig into your waist.
  • It makes it hard to button or zip your pants.
  • Bloating is often related to the buildup of fluid in your abdomen. It happens partly due to changes in your abdominal blood supply and your body’s ability to drain fluids.

    This fluid buildup is a concern because free-floating cancer cells can move through the fluid from one area of your body to another.

    2. Abdominal or pelvic pain

    One of the most commonly reported symptoms among people with ovarian cancer is pain in their abdomen and pelvis. In one study, around 39% of women with the diagnosis had experienced abdominal pain.

    What the pain feels like can vary from person to person. Some say it feels like intense pressure. Others say it feels like menstrual cramping, as though you’re being gripped or squeezed from within.

    Exactly what’s causing the pain can also differ. As tumors grow, they can put pressure on other parts of your body, including your bowels, bladder, rectum, and spine.

    3. Change in your bathroom habits

    About 20% of people with ovarian cancer notice constipation, diarrhea, or other bowel pattern changes.

    Ovarian cancer can also result in a need for more frequent urination or a greater sense of urgency about having to urinate. Around 7% say they experienced urinary problems before their diagnosis.

    In addition to urination frequency and urgency changes, some people also felt a burning sensation during urination, and others felt their bladder was still full even after urinating.

    4. Back pain

    Back pain is a common condition that affects millions of people every year. Most of the time, back pain is caused by injury, not cancer.

    If you haven’t injured your back or your back pain isn’t getting better with treatments, talk with a healthcare professional. Back pain can be a symptom of ovarian cancer.

    5. Appetite changes

    For some people, ovarian cancer causes a loss of appetite. Others may feel full even after eating just a small amount. Some have indigestion, nausea, or vomiting after they eat. These appetite changes can lead to unintended weight loss.

    It’s not uncommon for these symptoms to be misdiagnosed at first as acid reflux or a similar digestive condition.

    6. Menstrual changes

    If you have menstrual periods, ovarian cancer can affect your period in a number of ways. It may cause you to:

  • miss a period
  • bleed more heavily than usual
  • have spotting or bleeding when you’re not having a period
  • experience vaginal discharge that’s different from what you’re used to
  • In fact, research has found that a change from a regular to an irregular menstrual cycle can be a risk factor for ovarian cancer.

    If you are postmenopausal, talk with your doctor if you experience vaginal bleeding. Bleeding after menopause is sometimes a sign of ovarian cancer.

    Anytime your periods change, discussing what’s happening with a gynecologist, primary doctor, or another healthcare professional you trust is a good idea.

    7. Pain during sex

    Pain during sex is a lesser known sign of ovarian cancer. It can be caused by several other conditions, including:

  • vaginal dryness
  • endometriosis
  • vaginismus
  • inflammation
  • If sex is painful, a health professional can help you find out what’s causing the pain. Even if it’s not ovarian cancer, diagnosing and treating the problem can help you avoid emotional distress and physical symptoms.

    What are the risk factors for ovarian cancer?

    You may be at higher risk for ovarian cancer if you have:

  • a family history of ovarian cancer
  • a history of breast, gynecological, or colon cancer
  • BRCA1 or BRCA2 genetic mutations and the mutations that cause Lynch syndrome
  • obesity
  • never had a pregnancy
  • used hormone therapies or fertility drugs, though the research on this is not conclusive
  • have endometriosis
  • How is ovarian cancer diagnosed?

    Unlike other types of cancer, there’s currently no screening test to detect ovarian cancer at an early stage.

    There’s also no single test to detect ovarian cancer. Instead, your doctor will use several tests to look for a tumor in your ovaries and then test it to determine whether it’s benign or malignant (cancerous).

    The diagnostic tests most often used to detect ovarian cancer include:

  • Pelvic exam. Your doctor will feel your lower abdomen and pelvis to check for changes to the size and shape of your ovaries and uterus.
  • Transvaginal ultrasound. This involves inserting an instrument into your vagina which uses sound waves to create a picture of the inside of your fallopian tubes, ovaries, and uterus.
  • CA-125 blood test. This test detects higher levels of a protein sometimes produced by tumors.
  • CT scan. This test can visualize larger cancerous tumors.
  • How to be an advocate for yourself

    A delayed ovarian cancer diagnosis could have an impact on your life.

    Because there isn’t a regular screening test to detect early ovarian cancer and the symptoms overlap with other conditions, good treatment outcomes may depend partly on your ability to self-advocate.

    This may be especially important if you’re part of a group that’s often overlooked or underdiagnosed because of bias or racial inequities in healthcare.

    For example, a 2019 meta-analysis of 41 studies found a decrease of 25% in the receipt of ovarian cancer treatment and an 18% increase risk of mortality from ovarian cancer in Black people compared to people who are white.

    Self-advocacy isn’t always easy. It can be hard to talk about your symptoms, especially if you:

  • are a shy or reserved person
  • don’t know or fully trust your healthcare team
  • have depression or anxiety
  • don’t know what to ask for
  • are younger or less educated than your doctor
  • have experienced discrimination or disbelief because of your sex, gender identity, race, or income
  • have never had to advocate for yourself in a medical setting before
  • ASK FOR WHAT YOU NEED

    Here are some words of encouragement: Your symptoms are real. Your health is worth fighting for. It’s OK — it’s more than OK, it’s critical — to ask for what you need.

    Most people aren’t born with self-advocacy skills. They’re developed through practice — as though you are building muscle.

    Research involving women with ovarian cancer shows that self-advocacy has powerful effects, including:

  • you’re more likely to feel that your healthcare meets your needs and reflects your values
  • you’ll get more information to help you make better decisions
  • you’re more likely to get help for your symptoms before they become overwhelming
  • you’re more likely to create a supportive network around you
  • your overall well-being — including your mental and emotional health — is likely to improve
  • Strategies for building self-advocacy

  • Record your symptoms. In the days or weeks leading up to your appointment, document your symptoms to help your doctor understand the frequency and severity of your symptoms.
  • Communicate your risk. Make sure your doctor knows about your risk factors, including your family history and any BRCA1 and BRCA2 genetic mutations.
  • Emphasize what’s new. Because many symptoms of ovarian cancer are common, be sure you state clearly which symptoms are new and how long they have been happening.
  • Educate yourself. Find out everything you can about ovarian cancer and the diagnostic tests to detect it. Know where the tests take place, who orders them, and whether they’re covered by your insurance plan if you have one.
  • Prepare questions in advance. This step is important if you tend to become anxious in medical settings. To make sure you ask every question that matters to you, keep a notepad or your phone handy in the days before your office visit so you can jot down questions as they occur to you.
  • Involve your friends. If you have friends or relatives with cancer, ask them for guidance and support. What do they wish they’d done differently? How were they able to self-advocate? Would they be willing to role-play with you? In one study involving Black women with breast cancer, participants said the support they received from friends and family made a big difference in their ability to self-advocate.
  • Ask for a referral. If you feel your doctor is ignoring or minimizing your concerns, ask for a referral to a specialist. If you have health insurance, you can talk with your plan coordinator to see whether a referral is necessary.
  • Be polite and firm. A good healthcare partnership is based on two-way respect and trust. Asking may be more effective than demanding.
  • Find another doctor. Finding a new doctor can be time-consuming. Still, if you feel you’re not being heard, it is worth looking for a healthcare professional who sees you, hears you, and gives you person-centered care.
  • Resources and support for ovarian cancer

    Thinking about ovarian cancer can be frightening, whether you’re just beginning to gather information about your symptoms or much farther along in the process.

    It can be helpful if you have a variety of support systems around you. In addition to the support you have closer to home, here are some resources you may find helpful:

    Resources for you

  • the Ovarian Cancer Research Alliance (OCRA) Woman to Woman support and mentoring program
  • OCRA’s Inspire support groups online
  • the Ovarian Cancer Foundation’s patient resources list
  • the National Ovarian Cancer Coalition’s local chapters
  • Frequently asked questions

    Here are answers to additional questions about ovarian cancer detection and symptoms.

    How long can ovarian cancer go unnoticed?

    Many people can have no symptoms for many years. In fact, only 20% of ovarian cancer cases are diagnosed at an early stage. According to the 2018 Every Woman Study by the World Ovarian Cancer Coalition, for 1 in 10 women, it took over a year to receive a diagnosis after seeing a doctor about symptoms. It takes an average of 31 weeks to receive a diagnosis from the onset of noticeable symptoms.

    Would ovarian cancer show up in routine blood work?

    The CA-125 blood test can detect a protein called CA-125 in the blood, which could indicate ovarian cancer. However, this is not definitive. A rise in this protein can be caused by other conditions, and not everyone with ovarian cancer will see an increase in this protein in their blood.

    Can ovarian cancer cause weight gain?

    Ovarian cancer could cause weight gain. This usually results from the growth of the cancerous tumor or constipation caused by cancer.

    The bottom line

    Ovarian cancer doesn’t always have noticeable symptoms in its earliest and most treatable stages. When symptoms do show up, they are often misunderstood because they can mimic the symptoms of other conditions.

    Talk with a healthcare professional if you experience:

  • abdominal pain
  • bloating
  • pain in your back or sides
  • unexpected vaginal bleeding
  • missed periods
  • changes in your bowel habits or appetite
  • increased urgency or frequency of urination
  • painful sex
  • You may have to ask about ovarian cancer specifically because these symptoms are sometimes misdiagnosed at first — but do self-advocate. Your health depends on an early, accurate diagnosis.
