Peritoneal Mesothelioma - Mesothelioma Type

Shear Blog - Peritoneal mesothelioma develops in the peritoneal lining of the abdominal cavity. This is a relatively rare form of mesothelioma; approximately 10 to 20 percent of all mesothelioma cases are peritoneal in nature.

Symptoms of peritoneal mesothelioma include pain or swelling of the abdomen, changes in bowel habits (such as constipation or diarrhea), unexplained weight loss, and nausea or vomiting. These symptoms are caused by thickening of peritoneal membranes and fluid build-up, which puts pressure on internal organs and prevents normal function of some organs. As the cancer advances, people with peritoneal mesothelioma may notice lumps developing under the skin of the abdomen.

Diagnosis of peritoneal mesothelioma involves imaging tests such as CT scans and MRIs, as well as biopsies of fluid and tissue to detect the presence of mesothelioma cells. There is currently no recognized staging process for peritoneal mesothelioma.

Peritoneal mesothelioma is problematic in terms of treatment, because the cancer can spread quickly throughout the peritoneum and often metastasizes more quickly than other types of mesothelioma. In some cases surgery is possible, but this is typically a palliative treatment option.
