Peritoneal Mesothelioma: Symptoms and Treatment Options

Mesothelioma is a rare type of cancer that is caused by exposure to asbestos. It primarily affects the lining of the lungs, but it can also occur in the lining of the abdomen, known as peritoneal mesothelioma. In this article, we will discuss the symptoms and treatment options for this type of mesothelioma.

Symptoms of Peritoneal Mesothelioma

The symptoms of peritoneal mesothelioma can vary and may not appear until the cancer has advanced. Some of the most common symptoms of this type of mesothelioma include:

  • Abdominal pain and swelling
  • Nausea and vomiting
  • Loss of appetite
  • Weight loss
  • Fatigue
  • Bowel problems
  • Fluid buildup in the abdomen

If you have been exposed to asbestos and are experiencing any of these symptoms, it is important to see a doctor as soon as possible.

Diagnosing Peritoneal Mesothelioma

It can be difficult to diagnose peritoneal mesothelioma because its symptoms can mimic those of other conditions. To make a diagnosis, your doctor will likely perform a physical exam and order some tests, including:

  • Blood tests
  • Imaging tests, such as a CT scan or MRI
  • A biopsy of the affected tissue

If you have been diagnosed with peritoneal mesothelioma, your doctor will likely refer you to a specialist who can help determine the best course of treatment.

Treatment Options for Peritoneal Mesothelioma

The treatment options for peritoneal mesothelioma depend on the stage of the cancer and your overall health. Some of the most common treatment options include:

  • Surgery: If the cancer is in the early stages and has not spread, surgery may be an option to remove the affected tissue.
  • Chemotherapy: Chemotherapy is a common treatment option for mesothelioma. This type of treatment uses drugs to destroy cancer cells.
  • Radiation therapy: Radiation therapy uses high-energy rays to kill cancer cells. It may be used before or after surgery or as a standalone treatment option.
  • Immunotherapy: Immunotherapy is a newer treatment option that uses the body’s own immune system to fight cancer cells.

Your doctor may recommend one or a combination of these treatment options. It is important to discuss the potential benefits and risks of each treatment with your doctor before making a decision.

Coping with Peritoneal Mesothelioma

Receiving a diagnosis of peritoneal mesothelioma can be overwhelming. It is important to seek support from loved ones and to speak with a mental health professional if needed. There are also support groups available for individuals with mesothelioma.

Additionally, maintaining a healthy lifestyle can help improve your overall well-being. This includes eating a balanced diet, getting regular exercise, and managing stress. Your doctor may also recommend palliative care to help manage the symptoms of mesothelioma and improve your quality of life.


Peritoneal mesothelioma is a rare and aggressive type of cancer. Its symptoms can be difficult to detect, but early diagnosis is crucial for effective treatment. If you have been exposed to asbestos and are experiencing symptoms such as abdominal pain and swelling, it is important to see a doctor as soon as possible. With early detection and appropriate treatment, many individuals with mesothelioma are able to maintain a good quality of life.
