Mesothelioma: Scientific Evidence

Mesothelioma is a rare type of cancer that affects the membranes that line the internal organs. It is thought to be caused primarily by exposure to asbestos, a mineral that was used in a variety of products, including roofing, siding, and clothing

Mesothelioma: Scientific Evidence

There is strong scientific evidence to support the association between mesothelioma and asbestos exposure. Studies have shown that people who have been exposed to asbestos are up to 50 times more likely to develop mesothelioma than people who have not been exposed to asbestos.

Asbestos exposure can occur in the workplace or at home. In the workplace, workers can be exposed to asbestos during the removal or maintenance of asbestos products. People at home can be exposed to asbestos by breathing in asbestos-containing dust, which can be produced by construction, repair, or demolition of buildings that contain asbestos.

It can take many years for the symptoms of mesothelioma to appear after asbestos exposure. Symptoms of mesothelioma include cough, shortness of breath, chest pain, and weight loss.

There is no cure for mesothelioma, but there are treatments that can help relieve symptoms and improve quality of life. Pain can be treated with medication, radiation therapy, or surgery. Cough can be treated with medication or physical therapy. Shortness of breath can be treated with medication or oxygen.

If you think you may have been exposed to asbestos, it is important to see a doctor. The doctor can perform tests to determine if you have been exposed to asbestos and if you are at risk for developing mesothelioma.

**Specific evidence supporting the association between mesothelioma and asbestos exposure includes:**

* **Epidemiological studies:** These studies have shown a clear association between asbestos exposure and mesothelioma. For example, a study of shipyard workers in the United States found that those who were exposed to asbestos were 50 times more likely to develop mesothelioma than those who were not exposed.

* **Laboratory studies:** These studies have shown that asbestos can cause cancer in animals. For example, one study found that mice exposed to asbestos developed mesothelioma at a rate of 90%.

* **Cell culture studies:** These studies have shown that asbestos can damage cells and cause them to become cancerous. For example, one study found that asbestos could cause cells to become cancerous by damaging their DNA.

Based on the available evidence, it is clear that asbestos exposure is a major risk factor for mesothelioma.
