What are the symptoms of Abdominal mass?
Last updated September 7, 2026.
Many abdominal masses cause no symptoms and are found during an exam or scan, and when symptoms do occur the usual ones are a lump or firm area you can feel, swelling or bloating, and pressure or pain in one part of your belly. What you notice depends on where the mass sits and what it is. A mass pressing on the stomach or intestine can bring early fullness after small meals, nausea, constipation, or a change in stool shape, while one near the bladder can cause frequent or difficult urination. Masses in the upper right belly may come with yellowing of the skin or eyes, and any mass can be linked with unexplained weight loss or night sweats. Keep a short log of when you first felt the lump, whether it has grown, and what makes the discomfort better or worse, since that history guides testing. A lump you can feel in your abdomen always needs a clinician to examine it, because imaging and an exam are the only ways to tell a hernia, cyst, enlarged organ, or tumor apart.
What to do
- Get any new lump examined: Book a visit for a lump you can feel in your abdomen, even if it does not hurt.
- Note the pattern: Write down when you first noticed it, whether it has changed size, and any pain, bowel, or urinary changes.
- Watch for urgent signs: Seek same-day care for severe or sudden pain, fever, repeated vomiting, or a lump that pulses or grows quickly.
- Do not press or massage it: Repeated poking will not tell you what it is and can make a tender area worse, so leave the exam to a clinician.
- Bring your history: List past surgeries, hernias, liver or kidney problems, and family history of cancer, since these narrow the likely causes.
- Expect imaging: Ultrasound or CT plus blood work is the usual next step, and results guide whether treatment or monitoring is needed.
