Ovarian cancer often doesn't cause any symptoms until after it has spread outside the ovary. Even then, it often causes vague symptoms that are a lot like those caused by other, more common diseases. Common symptoms can include:

• Bloating or a sense of fullness, especially after eating
• Pelvic pain or cramping
• Trouble eating or feeling full quickly
• Urinary frequency or urgency
• Indigestion, heartburn, nausea, or gas
• Belly swelling or discomfort
• Back pain
• Constipation
• Tiredness and lack of energy (fatigue)
• Loss of appetite
• Unplanned weight loss or weight gain
• Vaginal bleeding or discharge
• Irregular periods
• Pain during sex

Many of these symptoms may be caused by other health problems. But it's important to see your doctor if you have these symptoms. Only a doctor can tell if you have cancer.
