Ovarian Cancer Symptoms

Ovarian Cancer Warning Signs


Updated May 20, 2014

Ovarian cancer is a type of cancer that affects the ovaries in women. It is often referred as the "silent killer" because ovarian cancer symptoms do not often appear until it is too late for effective treatment. Experts recommend that women who experience symptoms daily for three weeks or longer should see their doctor. Keep in mind that these symptoms are also signs of other, less serious conditions.

Ovarian Cancer Symptoms

Despite being touted as a "silent killer", experts have identified three symptoms that may aid in early detection. Symptoms include:

Symptoms of Advanced Ovarian Cancer

As ovarian cancer progresses, women may experience these symptoms:
  • Changes in bowel movements: Women may experience constipation, diarrhea, or other bowel changes as ovarian cancer spreads. The common symptoms of irritable bowel syndrome are often the same bowel change symptoms women experience with ovarian cancer.
  • Pain during sexual intercourse: The most common cause for pain during intercourse is lack of vaginal lubrication. In women with advanced ovarian cancer, pain during intercourse is usually experienced in the pelvis or the right or left side of the pelvis.

  • Persistent fatigue: Fatigue is the most commonly reported cancer symptom. If you consistently feel tired, you should be seen by your doctor. Fatigue is not unique to ovarian cancer and is common with many other less serious conditions. In women with ovarian cancer, as the disease progresses, the cancer cells compete with healthy cells for energy that results in fatigue.

  • Abdominal weight gain and bloating: Women with advanced ovarian cancer often experience marked change in the size of their abdomen. It is caused by the accumulation of fluid in the abdomen (distension). Please note that many other conditions can also cause distension and bloating, not just ovarian cancer.

  • Sudden weight gain or weight loss: Weight gain and weight loss are both symptoms of ovarian cancer. Again, it is a non-specific symptom and can be caused by another disease or condition.

Who is Most at Risk of Ovarian Cancer

Ovarian cancer most often occurs in women who are post-menopausal, have a family history of ovarian and/or breast cancer, suffer from obesity, and used estrogen replacement therapy. Ovarian cancer is not a common type of cancer, but is often fatal because it is diagnosed when the disease has spread, making treatment options limited or ineffective. While is is commonly known as the "silent killer" because there are often not any symptoms in the early stages, some experts believe that some women may experience early early warning signs.
