The short explanation
Persistent bloating is far more often caused by something else — digestion, constipation, irritable bowel, fibroids, cysts — but it is one of the symptoms worth getting checked, because ovarian cancer is easier to treat when found earlier. The pattern that matters is symptoms that are new, happen most days, and last for three weeks or more. Those symptoms are: persistent bloating or a swollen abdomen, feeling full quickly or losing appetite, pain in the lower abdomen or pelvis, and needing to pass urine more urgently or more often.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Ovarian cancer is more common after menopause and in women with a family history of ovarian or breast cancer, but it can occur earlier. There is no reliable screening test for women without symptoms, which is why knowing the pattern and acting on it matters.
- A clinician will usually start with an examination, a blood test called CA-125, and a pelvic ultrasound. A raised CA-125 can have many causes and does not by itself mean cancer.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you what is causing your bloating or whether you need tests. It cannot interpret a CA-125 result or a scan report.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- My symptoms have lasted this long — should I have a scan or blood test?
- What else could explain them?
- Does my family history change anything?
- If the tests are normal and symptoms continue, what happens next?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
- Get emergency care now (call 112 or 108) for sudden severe abdominal pain, a rapidly swelling hard abdomen, vomiting that will not stop, or fainting.
- See a clinician within days — do not wait for it to pass — if bloating, feeling full quickly, pelvic pain or urinary urgency are new and have been there most days for three weeks or more.
