What are the symptoms of ovarian cancer?

Symptoms of ovarian cancer can be vague and not always gynecologic, such as:

  • a swollen or bloated abdomen or increased girth (some women notice that their pants are getting tight around the waist)
  • persistent pressure or pain in the abdomen or pelvis
  • difficulty eating or feeling full quickly
  • urinary concerns, such as urgency or frequency
  • change in bowel habits with constipation and/or diarrhea

Any woman may have these symptoms for reasons not related to ovarian cancer. But if these symptoms are new and unusual, and persist for more than two weeks, a woman should see her doctor and ask about ovarian cancer.

Symptoms of ovarian cancer include:

  • bloating
  • pain in the belly
  • feeling tired
  • feeling the need to pee all the time

The following are symptoms of ovarian cancer:

  • Vague but persistent and unexplained gastrointestinal complaints such as gas, nausea and indigestion
  • Pelvic or abdominal pain (the area below your stomach and between your hip bones)
  • Backache
  • Bloating
  • Feeling full quickly while eating
  • Unexplained weight loss or weight gain
  • Unexplained changes in bowel habits
  • Frequency and/or urgency of urination
  • Vaginal bleeding or abnormal discharge from your vagina
  • Fatigue

These symptoms may be caused by something other than cancer, but the only way to know is to see a doctor. The earlier ovarian cancer is found and treated, the more likely treatment will be effective.

Unfortunately, symptoms of ovarian cancer are often vague in nature and tend to appear later, when an ovarian cancer is more advanced. These include abdominal distention, swelling and bloating; nausea, anorexia, early satiety or feeling full early after meals; dyspnea, due to buildup of ascites (abdominal fluid) and/or pleural effusions. In addition, urinary urgency or frequency may occur if there is disease near the urinary system. Clinical research is being done to try to identify these symptoms earlier in patients so that ovarian cancer can be detected and diagnosed at earlier stages to increase the rate of cure.

Some women describe ovarian cancer symptoms as similar to normal menstrual symptoms. Sometimes there is pain or increased frequency of urination. The symptoms can be pretty vague, which is what makes ovarian cancer a difficult cancer to detect early.

Often there are no symptoms of ovarian cancer, especially in the early stages. Some symptoms include abnormal vaginal bleeding, pain with intercourse, an abdominal mass, abdominal pain, pelvic pain, urinary symptoms of frequency and urgency, difficulty eating, early fullness, fatigue, back pain, constipation, and blood clots in one or both legs.

Unfortunately, the symptoms and signs of ovarian cancer often develop only after the cancer has begun to spread. The symptoms (complaints a patient has) are often vague. They include increasing abdominal girth, stomach or intestinal complaints (difficulty digesting, heartburn, bowel changes such as constipation,) or bloating.

The signs (findings that a healthcare provider will detect) are often similarly late in the disease process; these include a pelvic or abdominal mass or excess fluid in the abdomen or pelvis. Sometimes, the tumor is first detected on ultrasound (sonogram) or other imaging studies.

Ovarian cancer, a leading cause of death for women, often has no symptoms. In this video, Dr. Oz Show guest Sharyn Lewin reveals ways to reduce the risk of ovarian cancer.

The symptoms of ovarian cancer include pelvic discomfort, bloating, constipation, gas, nausea, lower back pain, fatigue, and pain while engaging in intercourse. You may have difficulty reaching the bathroom in time or you may notice differences in your menstrual cycle. You may also notice that your abdomen is larger and that your pants no longer fit.

Many ovarian cancer symptoms are vague or hard to detect and may be attributed to a less serious condition. Symptoms include:

  • Back pain
  • Fatigue
  • Abnormal bloating or a feeling of fullness
  • Abdominal pain or swelling
  • Nausea, constipation, or diarrhea
  • Urinary urgency
  • Pelvic pressure
  • Abnormal vaginal bleeding

Symptoms of ovarian cancer are vague and don't always point to the reproductive organs. Women may tend to see a variety of doctors like a gastroenterologist or urologist before they visit their gynecologist. These specialists will usually not perfom the necessary exams like a pelvic exam delaying the diagnosis of ovarian cancer.


  • Abdominal bloating: "My pants or skirt are too tight!" "I can't eat as much!"
  • Pesistent pain in the abdomen or pelvis
  • Changes in bowel habits: constipation or diarrhea
  • Changes in urinary habits: feeling of urgency or frequency
  • Vaginal bleeding: unexplained and lasting over two weeks

Early-stage ovarian cancer rarely causes any symptoms. Advance stage cancer can give you many non-specific symptoms: Abdominal bloating or swelling, weight loss or discomfort in the pelvis area.

Common symptoms of ovarian cancer include: appetite change, weight loss, and abdominal bloating/distention.

Ovarian cancer unfortunately has no definitive symptom. This is the reason why the majority of patients present in advanced stage. Subtle symptoms can be bloating, early satiety, and increase in waist size, pencil-like stools, and even nausea and vomiting. Screening tests for ovarian cancer are currently at best poor. Most studies have centered around ultrasound and a blood test known as CA125. Unfortunately, no study has proven that these are "good" tests in the general population.

Dr. Larry E. Puls, MD
Gynecologic Oncologist

The symptoms of ovarian cancer are often quite vague. That’s why a woman with this malignancy may perceive that something is not right, but have trouble pinpointing exactly what is going on inside of her.

There are a multitude of different symptoms that may occur in the early course of ovarian cancer making it hard to focus on any one single warning sign. The most frequent complaint is bloating coupled with a sense of fullness. This is caused by fluid accumulation from the cancerous process. The next most common complaint may be a gastrointestinal change like constipation, diarrhea, or early satiety (a sense not wanting to eat more after just a few bites of food). And of course there can be less common findings like bleeding abnormalities, pain, shortness of breath, or weight loss.

The signs of ovarian cancer may be different for each woman and any one of these symptoms may be caused by other, benign conditions. Because of the ovaries’ proximity to the bladder and the intestines, gastrointestinal symptoms often occur.

When present, common symptoms of ovarian cancer may include:

  • Persistent abdominal bloating, indigestion or nausea
  • Changes in appetite – often a loss of appetite, or feeling full sooner
  • Feelings of pressure in the pelvis or lower back
  • Needing to urinate more frequently
  • Changes in bowel movements
  • Increased abdominal girth
  • Feeling tired or low energy

Awareness of how your body normally feels and paying attention to symptoms that persist for several weeks can help guide your decision to see a doctor. Many signs of ovarian cancer, like abdominal bloating, may suggest a gastrointestinal issue. Talk with your doctor about ovarian cancer being part of the problem.

NOTE: These symptoms may be attributed to a number of conditions other than cancer. It is important to consult with a medical professional for an accurate diagnosis.

Ovarian cancer may cause several signs and symptoms. Women are more likely to have symptoms if the disease has spread beyond the ovaries, but even early stage ovarian cancer can cause them. The most common symptoms include: 

  • Bloating
  • Pelvic or abdominal pain
  • Trouble eating or feeling full quickly
  • Urinary symptoms such as urgency (always feeling like you have to go) or frequency (having to go often)

Other symptoms of ovarian cancer can include:

  • Fatigue
  • Upset stomach
  • Back pain
  • Pain during sex
  • Constipation
  • Menstrual changes
Dr. Sandra Cesario

Ovarian cancer is the most lethal of the gynecologic cancers because it often goes undetected due to lack of symptoms. When symptoms do occur, they are often in the form of vague complaints associated with other minor disorders and are often overlooked. Major cancer organizations agree that the four most common EARLY warning signs of ovarian cancer are:

  • Abdominal bloating, noticeable increase in abdominal girth 
  • Pelvic or abdominal pain 
  • Difficulty eating or feeling full quickly 
  • Urinary symptoms such as urgency or frequency

If any of these warning signs persist for more than a couple of weeks, it is important to seek medical care.

Because of the vagueness of these symptoms, ovarian cancer used to be called “the silent killer.” As we learn more about early warning signs, we now say "ovarian cancer whispers—listen!”
