C45-C49: Malignant neoplasms of mesothelial and soft tissue

C45: Mesothelioma

Mesothelioma is a rare form of cancer that develops in the lining of the lungs, heart, or abdomen. It is primarily caused by exposure to asbestos, a type of mineral fiber that was once commonly used in building materials. When asbestos fibers are breathed in or swallowed, they can become lodged in the body and disrupt cellular activity, which can lead to mesothelioma. Symptoms usually do not show until the disease has progressed and they may include shortness of breath, chest pain, or abdominal swelling. Depending on where the disease is located, it can affect the respiratory or digestive systems, and can cause serious health problems. The development and progression of mesothelioma varies and is dependent on many factors, including the patient's health and the extent of the asbestos exposure.
