What feels like simple gas, bloating, or period pain may sometimes be an early warning sign of ovarian cancer, doctors caution. The disease is often called a “silent killer” because its symptoms can be vague and easy to ignore in the beginning.
Here are some common symptoms that are often mistaken for normal digestive or menstrual issues:
- Persistent bloating or swelling in the abdomen
- Pelvic or lower stomach pain
- Feeling full very quickly while eating
- Frequent urge to urinate
- Gas, indigestion, or constipation that doesn’t improve
- Unusual fatigue or back pain
- Changes in periods or bleeding after menopause
The key concern is persistence. Occasional bloating or cramps are common, but if these symptoms continue for more than 2–3 weeks, become more frequent, or feel different from your usual cycle, doctors recommend getting checked.
Risk factors may include:
- Family history of ovarian or breast cancer
- Increasing age
- Obesity
- Endometriosis
- Never being pregnant
- Certain genetic mutations like BRCA1 or BRCA2
Doctors say early diagnosis can greatly improve treatment outcomes. Tests may include a pelvic exam, ultrasound, or blood tests such as CA-125, depending on symptoms and medical history.
Warning signs that need immediate medical attention
- Severe pelvic pain
- Sudden abdominal swelling
- Unexplained weight loss
- Bleeding after menopause
- Constant digestive discomfort without a clear reason
