Cancer occurs when cells in the body divide without control or order. If cells keep dividing uncontrollably, a mass of tissue forms. This 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.
Asbestos is a fibrous mineral that is known to cause cancer. This type of cancer is almost always caused by exposure to it. Even a small amount of exposure can be a risk.Other fibers can cause mesothelioma.
Factors that may increase your chance of getting pleural mesothelioma include:
This cancer can take up to 20-40 years to develop. Early signs of pleural mesothelioma include:
Many people do not have symptoms for a long period of time.
Your doctor ask about your symptoms and medical history. A physical exam will be done. You may be referred to a doctor who specializes in lung problems or cancer. A pulmonologist focuses on the lungs. An oncologist focuses on cancer.
