Symptoms of Peritoneal Mesothelioma
Recognizing Signs of a Rare Abdominal Cancer Linked to Asbestos Exposure
Peritoneal mesothelioma develops in the lining of the abdominal cavity—the peritoneum—and its symptoms often mimic more common digestive or gynecological conditions. For individuals with a history of asbestos exposure, understanding these symptoms is essential to ensure timely diagnosis and treatment.
Why Symptoms Are Often Misdiagnosed
Because the symptoms affect the stomach and intestines, many people are first misdiagnosed with:
Irritable Bowel Syndrome (IBS)
Gallbladder or liver disorders
Ovarian cancer (in women)
General GI distress or “bloating”
This confusion can delay proper testing, allowing the cancer to progress. Knowing the warning signs and communicating your exposure history can help you get the right care sooner.
Common Symptoms of Peritoneal Mesothelioma
🔹 Abdominal Pain or Swelling
What it feels like: Constant or recurring pain in the belly, often accompanied by bloating or visible swelling.
Why it happens: Tumors or fluid (ascites) stretch and inflame the abdominal lining.
🔹 Nausea or Vomiting
What it feels like: Upset stomach, vomiting after meals, or pressure on the digestive system.
Why it happens: Cancer growth or fluid buildup can compress the stomach or intestines.
🔹 Loss of Appetite and Weight Loss
What it feels like: Feeling full quickly, eating less, or losing weight without trying.
Why it happens: Pressure from fluid or tumors limits stomach capacity and disrupts digestion.
🔹 Bowel Changes or Obstruction
What it feels like: Constipation, diarrhea, or erratic bowel habits.
Why it happens: Tumors pressing on the intestines can interfere with normal movement. In severe cases, bowel obstruction may occur.
🔹 Ascites (Abdominal Fluid Build-Up)
What it feels like: Heaviness, bloating, or tightness in the belly.
Why it happens: The peritoneum becomes inflamed, causing fluid to accumulate. This is one of the most common and visible symptoms.
🔹 Fatigue and Weakness
What it feels like: Unusual tiredness that doesn't improve with rest.
Why it happens: Chronic inflammation and nutritional deficits sap the body’s energy.
🔹 Feeling of Fullness
What it feels like: Pressure after small meals or feeling like you “can’t fit more” in your stomach.
Why it happens: Fluid or tumors take up space in the abdomen, limiting normal organ function.
🔹 Shortness of Breath (Advanced Cases)
What it feels like: Trouble breathing when lying flat or climbing stairs.
Why it happens: Severe abdominal swelling can push up on the diaphragm, restricting lung movement.
🔹 Lower Back or Leg Pain
What it feels like: Dull aching or pressure in the back or legs.
Why it happens: Tumors or fluid buildup may affect nearby nerves or blood flow, causing referred pain or swelling.
🔹 Indigestion or Heartburn
What it feels like: Burning, belching, or discomfort after eating.
Why it happens: Tumors and fluid disrupt normal stomach and digestive activity.
Don’t Ignore Persistent Abdominal Symptoms
If you’ve had known or possible asbestos exposure—even years ago—and are now experiencing these symptoms, don’t assume it’s just IBS or indigestion. Ask your doctor about imaging and specialist referral.
Peritoneal mesothelioma has a long latency period. Symptoms often appear 20–50 years after exposure.
