Peritoneal Mesothelioma Causes

Peritoneal mesothelioma symptoms may resemble those of many other diseases that make it difficult for doctors to recognize the cancer at an early stage. Patients may feel abdominal discomfort, distention, abdominal ascites and weight loss.

Doctors employ a combination of imaging, bloodwork and surgical procedures to diagnose mesothelioma. They also examine the patient's medical history and work history to determine if asbestos was a factor.

Asbestos Exposure

When asbestos is disturbed it breaks down into tiny fibres that can be easily inhaled. These tiny fibers can get stuck in the lung and cause inflammation, scarring, and tumor growth. This is known as mesothelioma or asbestosis.

When asbestos-containing air is inhaled, these asbestos fibers may enter the lymphatic and digestive tract systems. Once they reach the tissues of the peritoneal region, they could be trapped within them and cause irritation over time. This can cause inflammation scar tissue formation, as well as genetic damage that allows cancer cells to develop.

Exposure to asbestos is the only known cause of peritoneal mesothelioma. However, this type of mesothelioma has a lower incidence than the more widespread mesothelioma pleural.

The most commonly reported symptoms are abdominal swelling and pain. People who are exposed to asbestos may also experience nausea, vomiting, and constipation. These symptoms can be reminiscent of other gastrointestinal conditions, such as colitis and diverticulitis. This can delay diagnosis. This can make it difficult for doctors to determine whether the patient has peritoneal asbestosis.

If a physician suspects that mesothelioma is present, they will perform an examination and take a medical history. A chest X-ray and CT scan will be taken to check for signs of inflammation or abnormalities. These tests can help doctors identify mesothelioma, and the possible causes.

The vast majority (over 90%) of mesothelioma cases are caused by asbestos exposure at work. A large portion of the patients are veterans and the VA offers benefits to those exposed to asbestos during their military service. Asbestos victims are encouraged to examine their eligibility for VA compensation.

The most effective treatment for mesothelioma is a combination of surgery and heated chemotherapy. This treatment can dramatically increase the life expectancy of a patient.

Genetic Predisposition

In some cases, asbestos exposure can lead to peritoneal msothelioma due to a genetic predisposition. Mesothelioma is a rare cancer, isn't often seen. Researchers are working to better understand what factors make someone susceptible to develop it. The genetic predisposition to mesothelioma can help doctors predict those at risk and offer patients life-extending treatments.

Researchers have discovered that some gene mutations increase the risk of developing mesothelioma. Genes that are affected by mutations like BAP1, NF2, CDKN2A, and CDKN2B are known as cytogenetic changes. These mutations cause cells to grow in uncontrolled ways and develop tumors.


Different mesothelioma types have different prognoses as well as responses to treatment. The epithelioid type is more likely to respond to treatment and have a lower risk of recurrence compared to the more aggressive sarcomatoid type or biphasic type that has both epithelioid and sarcomatoid like cells.

Scientists have discovered that changes in cytogenetics can result in various subgroups of mesothelioma including Group 1 which is characterized by BAP1 alterations and NF2 or CDKN2A/B. This group is more likely to die when compared to other groups. This suggests that genetic changes could be used by doctors to treat peritoneal cancers with an individualized treatment.

A palliative specialist can prescribe medication to alleviate discomfort and symptoms such as nausea, vomiting, or fatigue. A palliative care specialist can also refer patients to occupational or physical therapy or suggest alternative treatments.

Patients with peritoneal msothelioma can inquire from their oncologists if they are able to participate in clinical trials. These trials test experimental treatments for safety and effectiveness to determine whether it will prolong the lives of mesothelioma patients. Patients can learn more about clinical trials in peritoneal cancer by contacting a mesothelioma specialist or using our free Patient Assistance Program. A mesothelioma expert will review your biopsy to determine the most effective treatment plan based on your cell type and the stage of mesothelioma. This could include a combination of chemotherapy, surgery and immune therapy.

Radiation of the abdomen

Patients with peritoneal mesothelioma can experience a wide array of symptoms including abdominal discomfort distention, swelling, weight increase, constipation, fever and diarrhea. In most cases, these symptoms begin after exposure to asbestos and last for a long time before mesothelioma is identified. These signs can be mistaken as other health problems. Mesothelioma misdiagnosis can lead to delays in the treatment. Therefore, patients with mesothelioma of the peritoneal region should consult an expert physician as soon as they experience any symptoms to ensure that they receive a proper diagnosis.

A mesothelioma expert can help diagnose peritoneal mesothelioma and recommend the most appropriate treatment option for each patient's unique situation. The first step in establishing an accurate diagnosis is to conduct an examination and X-rays. Doctors can also order an PET or MRI scan to examine the abdomen's lining. In some instances doctors may perform a biopsy to confirm the diagnosis of peritoneal cancer. Biopsies are samples of tumor tissue which are sent to a lab for testing. Tests can reveal the type of mesothelioma a patient has, regardless of whether it is epithelioid, or sarcomatoid.

Mesothelioma specialists use an assessment system for grading to determine the degree to which a patient's mesothelioma is. The staging system reflects how far the cancer has spread. Stage 1 is the most advanced, whereas stage 4 is the most advanced.

Doctors can treat peritoneal cancer using either chemotherapy or surgery. Chemotherapy drugs such as pemetrexed, gemcitabine and cisplatin can shrink mesothelioma tumors. Additionally, what is mesothelioma cancer caused from can reduce the risk of recurrence and extend the duration of life.

Surgery is typically reserved for peritoneal mesothelioma that is in its early stages. Surgeons can undergo the procedure known as cytoreductive surgery using heated intraperitoneal chemotherapy (HIPEC). HIPEC involves injecting large doses of heated chemotherapy drugs into the abdomen following surgery to remove large parts of the mesothelioma. The treatment was developed by Dr. Paul Sugarbaker, a mesothelioma expert.

Patients who are not able to undergo surgical treatment for their peritoneal mesothelioma can receive palliative care instead. This could include a fluid drainage procedure called paracentesis which involves inserting a tube into the abdomen to drain excess fluid. Patients who have a more advanced mesothelioma should consider participating in immunotherapy-focused clinical trials as a possible way to extend their survival.

Other Reasons

Mesothelioma is an asbestos-related cancer that affects the lining of organs in the chest and abdomen. Mesothelioma is a form of cancer that develops when cells within the mesothelium turn malignant and begin to grow out of control. It can spread to the lungs or heart. Mesothelioma is diagnosed later when the symptoms are more severe.

The most frequent peritoneal mesothelioma symptoms and signs are abdominal swelling or pain ascites (fluid in the abdomen), and the sensation of bloating. In some cases, these symptoms are so similar to other ailments that it is difficult for doctors to identify mesothelioma, especially in early stages. Mesothelioma specialists may use the procedure of a biopsy to establish an accurate diagnosis.

Symptoms may not show up until the cancer is in an advanced stage. Once symptoms appear, they are typically persistent and may include bloating or stomach pain, constipation, diarrhea and fatigue. It is crucial that asbestos victims seek medical attention from a mesothelioma specialist whenever they experience any of these symptoms.

The survival rate of mesothelioma in the peritoneal region is on many factors, including the patient's overall health, the cancer stage and the type of cell. People who undergo surgery and receive heated chemotherapy have the highest chance of surviving longer. Women and those born female have a greater chance of surviving than males or those born male.

Doctors also consider a person's age when making an appropriate treatment plan. It is more effective to treat mesothelioma in its earlier stages prior to it having developed the potential to grow.

Certain patients with advanced-stage peritoneal mesothelioma might not be suitable for chemotherapy or surgical procedures dependent on their condition and the extent to which the cancer has spread. Palliative medicine can be used to control symptoms, including medication that eases pain and fluid accumulation in the abdomen. The excess fluid, called ascites, can be drained with a thin needle in a procedure called abdominal paracentesis, also known as an ascitic tap. Radiation can also be used to target a tumour and relieve uncomfortable symptoms. In some cases mesothelioma specialists use various treatments to provide the best results for their patients.
