What Is Mesothelioma?

Malignant mesothelioma, often referred to simply as mesothelioma, is a type of cancer that affects the mesothelium — the protective lining of the lungs, abdomen, and heart. It is caused by exposure to asbestos, a carcinogenic mineral that was used for decades in a number of commercial and residential applications, and is the most severe of all asbestos-related illnesses. Due to its long latency period, mesothelioma is usually diagnosed at advanced stages and often occurs in older people. While the prognosis for mesothelioma has been historically poor, advancements in treatment options offer patients newfound hope for longer survival and a better quality of life.

There are approximately 3,300 new cases of mesothelioma diagnosed each year. Due to the high number of occupational-exposure cases, patients may be eligible to receive discounted treatment or financial compensation.

Mesothelioma Symptoms

Mesothelioma occurs as a result of inhaled or ingested asbestos fibers. Common symptoms may mimic the flu or pneumonia. These include shortness of breath, fever, chest pain, wheezing or a cough, and weight loss. Patients exhibiting symptoms should visit their doctor right away. The earlier mesothelioma is diagnosed, the better the prognosis, as more extensive treatment offerings are usually available.

Diagnosing Mesothelioma

Diagnosing mesothelioma is difficult, as its symptoms are often mistaken for other conditions. Doctors also struggle to diagnose the disease because of its rarity and because of its extremely long latency period. Imaging scans, blood tests, and biopsies are used when identifying the presence and stage of mesothelioma. Information gained from the diagnosis is also used to determine a treatment plan.

Types of Mesothelioma

There are three main types of mesothelioma: pleural, peritoneal, and pericardial. Pleural mesothelioma accounts for the majority of cases, followed by peritoneal mesothelioma. Pericardial and testicular are extremely uncommon, accounting for less than 5 percent of all cases. The location of mesothelial tumors in the body is a major determinant of courses of treatment.

Mesothelioma Tumor Cell Types

The type of cell present in mesothelioma tumors can significantly affect a patient’s prognosis and treatment options. Tumors are categorized either as epithelioid, sarcomatoid, or a combination of the two, referred to as biphasic.

Mesothelioma Staging

Mesothelioma, like other cancers, is staged from 1 to 4. Stages 1 and 2 are less severe and more treatable. Advanced stages have a poor prognosis, as the disease becomes more difficult to treat.

  • Stage 1
    • Cancer is localized within the body
    • Curative treatment options are generally available
    • Average life expectancy of 21 months
  • Stage 2
    • Minimal metastasis (spreading) throughout the body
    • Curative treatment options are generally still available
    • Average life expectancy of 19 months
  • Stage 3
    • Cancer has spread to the lymph system and surrounding organs
    • Fewer treatment options available, tends to be more palliative care
    • Average life expectancy of 16 months
  • Stage 4
    • Cancer has spread to the lymph nodes and distant organs
    • Treatment options are strictly palliative at this stage
    • Average life expectancy of 12 months

Treating Mesothelioma

Treatment for mesothelioma varies, primarily based on the type, stage, and cell type of each patient’s unique case. Generally, chemotherapy, radiation, and surgery are used to create a specialized multimodal treatment plan. Curative treatment options may be available to patients diagnosed in stages 1 and 2, however, as the cancer advances, treatment options become limited to palliative care.

New treatments and advancements in current treatments offer mesothelioma patients hope of fighting the disease. As a patient, it’s important to seek specialized treatment right away. You may also be eligible for clinical trials that could potentially improve your prognosis. Learn more about mesothelioma treatment option.

Pleural vs. Peritoneal

  • Treatment is largely dependent on the location of mesothelioma tumors in the body. Pleural mesothelioma affects the lungs and tends to carry a worse prognosis than peritoneal mesothelioma, which affects the abdomen. This is mainly due to less-effective treatment options available for pleural mesothelioma.

Palliative vs. Curative

  • When it comes to differences in care, curative treatment options aim to completely eradicate the cancer. Often this is only available in early-stage diagnoses. Palliative care refers to treatment options that seek to relieve patient pain and discomfort.

Mesothelioma Compensation and Benefits

Lawsuits and asbestos trusts

Negligent asbestos exposure accounts for half of all occupational cancer deaths. Unfortunately, asbestos companies and employers knew the dangers of asbestos and still placed the health of their employees at risk. Asbestos trust funds have been established to compensate victims of wrongful occupational exposure, totaling an estimated $37 billion. If you or a loved one has been diagnosed with mesothelioma, you may be eligible for financial assistance to help recover lost wages and cover the burdensome costs of treatment. Learn more about mesothelioma legal compensation.

VA claims

Veterans account for nearly 30 percent of all mesothelioma cases. If you served in the military and have been diagnosed with mesothelioma or another asbestos-related illness, you may be eligible for VA compensation. Learn more about mesothelioma and veterans.
