What happens if ovarian cancer is not treated?

Short answer
If ovarian cancer is not treated, it may grow or spread within the abdomen and cause worsening pain, swelling, digestive symptoms, or fluid build-up.
This answers one question. It is not a diagnosis and does not replace an assessment by a licensed doctor.
At a glance
- Possible complication
- Fluid in the abdomen can cause pressure, swelling, appetite changes, or breathlessness.
- Treatment planning
- Tumour features, stage, health, and genomic findings may influence care.
Possible effects of progression
Ovarian cancer can involve the ovaries, fallopian tubes, pelvic tissues, or lining of the abdomen. As it grows, it may press on the bowel or bladder, causing fullness, constipation, urinary changes, or abdominal discomfort. Cancer cells may also spread beyond the pelvis.
Fluid collecting in the abdomen is called malignant ascites. It can make the abdomen feel tight or swollen and may affect appetite, movement, or breathing. Abdominal swelling has several possible causes, so it needs assessment rather than a conclusion based on the symptom alone.
What to do now
Arrange prompt review with a gynaecologic oncology team if ovarian cancer is suspected or confirmed. Evaluation may include examination, blood tests, imaging such as pelvic ultrasound, and tissue assessment. Genomic tumour profiling and information about BRCA gene mutation or Lynch syndrome may help guide treatment choices.
Treatment plans differ according to stage, tumour features, symptoms, and general health. Ask about surgery, systemic treatment, symptom control, and how to manage eating, activity, and abdominal pressure while decisions are made.
When to seek urgent care
Seek urgent help for severe or rapidly increasing abdominal swelling, new breathing difficulty, persistent vomiting, inability to keep fluids down, fainting, severe pain, or inability to pass stool or gas. Contact the care team quickly if symptoms suddenly change.
Questions for your doctor
Where has the cancer been found, and what tests clarify its extent? Is fluid present in the abdomen? Would genomic profiling be useful? Which treatments and symptom-support options fit my situation?
Questions people ask
Does abdominal swelling mean ovarian cancer?
No. Abdominal swelling can result from many conditions. Persistent or new swelling should be assessed to identify its cause.
Can ovarian cancer spread if untreated?
It can extend through pelvic and abdominal tissues and may spread to more distant sites. The pattern varies, so staging tests are needed.
