What is Mesothelioma

Mesothelioma is a rare and aggressive cancer that forms in the mesothelium, the thin layer of tissue that lines the lungs, chest wall, abdomen, heart, and other internal organs. The disease is most often linked to past exposure to asbestos, a group of naturally occurring mineral fibers that were widely used in construction, manufacturing, and other industries for much of the 20th century.

Types of mesothelioma

Mesothelioma is classified by where it develops. The most common form is pleural mesothelioma, which affects the lining of the lungs and chest cavity. Peritoneal mesothelioma develops in the lining of the abdomen, while pericardial mesothelioma affects the lining of the heart. A very small number of cases involve the lining of the testicles. Each type has its own set of symptoms, but all are serious and require specialized care.

How asbestos exposure leads to mesothelioma

When asbestos-containing materials are disturbed, they release tiny fibers into the air. If inhaled or swallowed, these fibers can become lodged in the mesothelium. Over time, the fibers cause irritation, inflammation, and scarring that can eventually lead to cellular changes and cancer. The disease has a long latency period, often taking 20 to 50 years after exposure before symptoms appear. This means a person may have been exposed to asbestos decades before any diagnosis is made.

Symptoms and diagnosis

Symptoms vary by type. Pleural mesothelioma commonly causes shortness of breath, chest pain, a persistent cough, and fluid buildup around the lungs. Peritoneal mesothelioma may cause abdominal pain, swelling, nausea, and weight loss. Because these symptoms overlap with many other conditions, mesothelioma can be difficult to diagnose. Doctors typically use imaging scans, biopsies, and a review of the patient's work and exposure history to reach a diagnosis.

Mesothelioma in Missouri

Missouri residents may have been exposed to asbestos in a number of settings. The state has a long industrial history, including power plants, manufacturing facilities, chemical plants, and construction sites where asbestos-containing materials were common. The Mississippi and Missouri rivers supported barge and shipbuilding operations that used asbestos for insulation and fireproofing. Older homes, schools, and commercial buildings across the state may still contain asbestos in flooring, ceiling tiles, pipe insulation, and siding. Vermiculite ore, which can be contaminated with asbestos, was also processed in parts of the region. Anyone who worked in these industries, or lived with someone who did, may have been exposed.

What to do if you are concerned

If you or a family member worked around asbestos or lived in a building with aging asbestos materials, it is reasonable to mention that history to a doctor. Early detection can improve treatment options, though there is no cure for mesothelioma. Treatment typically involves surgery, chemotherapy, radiation, or a combination of these, depending on the stage and location of the disease. Clinical trials may also be available at specialized cancer centers.
