Symptoms of Peritoneal Cancer

Peritoneal Carcinomatosis Symptoms

There may be no symptoms in the early stages, or you may have vague symptoms that resemble other conditions. In later stages, the cancer causes symptoms such as:

• Diarrhea, constipation, or nausea
• Abdominal pain
• Bloating
• Weight loss or gain
• Peeing a lot
• Loss of appetite or feeling full when eating

Many other things can cause those problems.

Peritoneal carcinomatosis that stems from abdominal cancers can lead to ascites (the buildup of fluid in the peritoneum), which then leads to other symptoms such as:

• Swelling of the abdomen or ankles
• Breathing problems
• Extreme fatigue
• Loss of appetite
• Unusual weight gain from fluid accumulation
• Lower back pain
