What is Mesothelioma?
Malignant mesothelioma is a rare and serious cancer caused by exposure to asbestos. It takes 20 to 50 years to develop and occurs in the lining of the lungs, chest, abdomen and heart.
Where Does Mesothelioma Develop?
Cancer of the mesothelium in the lungs is known as pleural mesothelioma. It accounts for 3 out of 4 mesothelioma diagnoses because most asbestos fibers are inhaled, lodging into the lining of the lungs.
Cancer of the mesothelium surrounding the abdomen is known as peritoneal mesothelioma. It is caused by ingesting asbestos fibers and accounts for about 20 percent of all diagnoses.
Cancer of the mesothelium surrounding the heart is known as pericardial mesothelioma. This is a rare form of mesothelioma and is not usually diagnosed while the patient is still alive.
Mesothelioma can also develop in the lining of the testicles. Testicular mesothelioma is extremely rare and occurs in less than 1 percent of mesothelioma cases.

Malignant mesothelioma is almost exclusively tied to prolonged asbestos exposure. Asbestos is a naturally occurring mineral that became very popular in the 20th century due to its heat resistance and insulating properties. Asbestos has been used in a variety of products from building materials to car parts.
In most cases, these fibers are inhaled and end up in the lining surrounding the lungs and chest, known as the pleura. In other cases, the fibers may be ingested and end up in the lining of the stomach and abdomen, known as the peritoneum.
In rare cases, asbestos fibers find their way to the pericardial lining surrounding the heart and cause pericardial mesothelioma. The causes of this type of mesothelioma are still being explored.
Since asbestos was widely used in industrial and commercial products, a large number of individuals have been exposed to this toxic substance. People such as factory workers, shipbuilders, military veterans or insulation manufacturers who worked with asbestos while removing or installing it are at risk of developing mesothelioma.
Family members of those who worked with asbestos are also at risk of developing mesothelioma. Asbestos fibers and dust carried into the home on work clothes could have been inhaled by family members. This is referred to as “secondary exposure.”
Selecting a Top Doctor is Critical
Selecting a mesothelioma specialist is the most important decision a patient can make. A general oncologist (cancer doctor) simply does not have the experience dealing with mesothelioma that a specialist has.
Mesothelioma specialists are not as common as other doctors because of the extreme rarity of mesothelioma (2,000 to 3,000 cases every year). Use our free Doctor Match program to find a mesothelioma specialist near you. Treatment prescribed by a mesothelioma specialist can significantly extend a patient’s life.
Medical imaging options include X-Rays, CT scans and PET scans. A doctor usually begins with an X-Ray to determine whether there are any irregularities in the patient. Following these imaging tests, a doctor may order a blood test for further evidence of the presence of mesothelioma. When cancer cells are present in the body, there are numerous proteins released that may be measured through a blood test.
Most mesothelioma biopsies are major surgeries and may require a multi-day hospital stay. The biopsy also determines cell type of the cancer, which can be epithelioid, sarcomatoid or biphasic. All of this testing provides mesothelioma specialists with the information they need about the cancer to treat it effectively.
Mesothelioma is localized to the point of origin. There is no lymph node involvement in this stage. Diagnoses at this stage are rare.
Mesothelioma remains confined to the point of origin. Regional lymph nodes may be affected. Patients at this stage still have many treatment options, including aggressive surgery.
Mesothelioma has spread beyond the point of origin. Additional lymph nodes are affected. Surgery may still be an option at this stage.
Mesothelioma has spread to other organs and lymph nodes. Organ failure is possible at this stage. This stage has the fewest treatment options, so it is absolutely imperative to see a specialist.
Based on the stage of the patient’s disease, specialists either prescribe treatments to remove the cancer and extend life or simply focus on limiting patient discomfort. It should also be mentioned that there are several staging systems for mesothelioma, and a doctor might see different opportunities for treatment based on the system they follow. This is an important reason why patients should always consider getting a specialized second opinion.
Though typically only available in the first two stages, surgery is the only treatment option known to significantly extend life.
Chemotherapy circulates medication through the bloodstream, which slows or kills additional cancer growth.
High levels of radiation targeted at the affected area may kill cancerous cells and stop the growth of new cells.
A specialist combines a number of different treatment options to combat mesothelioma, such as surgery and chemotherapy.
There are many clinical studies being conducted to evaluate and develop new treatments. These clinical trials are an additional option to consider for patients and may lead to a future cure.
Some survivors credit alternative health options as instrumental in their recovery. Examples include yoga, meditation, and acupuncture.
Ways to Improve Prognosis
1Find a Mesothelioma Specialist – Seeing a specialist is the most important way to improve prognosis. Specialists have experience treating mesothelioma that general oncologists don’t have.
2Get a Second Opinion – Always seek a second opinion before accepting a treatment plan. Second opinions may reveal more treatment options that lead to longer survival.
3Explore Treatment Options – Patients should explore all their treatment options with their doctor and decide the best plan based on their diagnosis. Every diagnosis is different and certain treatments work better for certain patients.
4Maintain a Healthy Lifestyle – Patients who maintain a healthy lifestyle are more resilient to aggressive treatment and are more capable of fighting the disease.
5Enroll in Clinical Trials – Participating in a clinical trial can provide access to treatment methods not offered elsewhere. Talk to your specialist about clinical trials that may improve your prognosis.
