Pleural mesothelioma is cancer of the membrane (pleura) that lines the outside of the lungs and the inside of the chest.
Cancer happens when cells in the body divide without control or order. A mass of tissue can form when this happens. It is called a growth or tumor. The term cancer refers to malignant tumors. They can invade nearby tissue and spread to other parts of the body.
Mesothelioma is a type of cancer. It is almost always caused by being around asbestos. This is a loose mineral that is found in building materials and car parts.
Things that may raise the risk are:
This cancer can take up to 40 years to happen. It may cause:
The doctor will ask about your symptoms and health history. You may also be asked about any exposure to asbestos. A physical exam will be done. You may be referred to a doctor who treats the lungs or one who treats cancer.
Blood tests may be done to look for signs of cancer.
Images will be taken of the chest or abdomen. This can be done with:
A biopsy will be done to confirm the diagnosis. Fluid from the chest cavity may also be tested.
More tests will be needed to find out if the cancer has spread. This is called staging. It helps guide treatment.
Treatment will be based on the stage of cancer. The plan will often have more than one type of therapy. Choices are:
Pleural fluid caused by the tumor will be removed to ease breathing. This is repeated as needed.
The only known way to prevent this cancer is to avoid asbestos and hazardous fibers.
