Causes

What are the main causes of mesothelioma?

Mesothelioma is most predominantly caused by asbestos exposure. Asbestos fibers that are inhaled through the mouth and nose may eventually become embedded in the lining of the lungs, causing damage and resulting in lung cancer or asbestosis (scar tissue formation in the lungs). It has also been found that swallowing asbestos fibers could contribute to a form of mesothelioma originating in the abdomen called peritoneal mesothelioma.

Mesothelioma generally results from occupational exposure but there are instances of environmental exposure to asbestos that can cause the disease. Oftentimes second hand exposure of a family member to an asbestos workers dirty work clothes can result in that family member developing mesothelioma.

Asbestos insulation workers appear to have the highest death rate. One study reports that almost six percent of asbestos workers fall victim to mesothelioma and asbestos insulation workers are over 300 times more likely to die from mesothelioma than the general public.

Symptoms

What are the warning signs of mesothelioma?

Mesothelioma is difficult to diagnose because the early signs and symptoms of the disease can be subtle at best. Symptoms are all too frequently ignored or dismissed by people who are inclined to attribute them to common every day ailments. Sometimes patients live with symptoms for up to 6 months before being diagnosed but usually the symptoms are present for two to three months prior to diagnosis.

About 60% of patients diagnosed with pleural mesothelioma experience lower back pain or side chest pain and there are frequent reports of shortness of breath. Lower numbers of people may experience difficulty swallowing, or have a persistent cough, fever, weight loss or fatigue. Symptoms to also consider are muscle weakness, loss of sensory capability, coughing up blood, facial and arm swelling and hoarseness.

Peritoneal mesothelioma originates in the abdomen and as a result, symptoms often include abdominal pain, weight loss, nausea, and vomiting. In the event that there is a hernia present, fluid build up may occur in the abdomen as well.

Anyone previously exposed to asbestos displaying any of these symptoms should seek medical attention right away.
