Asbestos exposure-What are the 4 diseases that are commonly ...

Most people don?t show any signs or symptoms of asbestos-relateddisease for 10 to 20 years or more after exposure. When symptoms doappear, they can be similar to those of other diseases.Asbestos-related diseases can be divided into 1} cancerous and 2} noncancerous diseases:-

Non-cancerous diseases

Asbestosis

This disease is characterized by scarring of the lungs. It is commonlyoccurs as result of exposure to high levels of asbestos over a longperiod of time, as seen in work-related asbestos exposure. Smokingincreases the risk of developing asbestosis. Initially there are nosymptoms but latter some symptoms which show up include difficulty inbreathing, chronic cough and chest pain.

Pleural changes or pleural plaques

This disease is characterized by thickening and hardening of the pleura(the pleura is the lining that covers the lungs and chest cavity). Mosttime the disease is asymptomatic {the people will have no symptoms},but sometimes the affected victims may have decreased lung function.This might lead to the development of difficulty in breathing withexertion or sometimes at rest if the degree of lung dysfunction issevere.

Cancerous diseases

Lung cancer

This is cancer of the lungs and lung passages. Cigarette smokingcombined with asbestos exposure greatly increases the likelihood oflung cancer. Lung cancer caused by smoking or asbestos looks the same.Symptoms for lung cancer can vary. Some late stage symptoms can includechronic cough, chest pain, unexplained weight loss, and coughing upblood.

Mesothelioma

This is a rare cancer mostly associated with asbestos exposure. Itaffects the lining of the lungs and sometimes the lining of theabdomen. Occasionally it affects the lining of the heart and the liningof the testis. Symptoms include chest pain, persistent shortness ofbreath, and unexplained weight loss, abdominal swelling and abdominalpain in case of abdominal mesothelioma. Other less common symptomsinclude haemoptysis {coughing up of blood} and excessive sweating.

These asbestos-related diseases can be serious, though not everyoneexposed to asbestos gets health problems. These diseases range formthose that are mild and manageable to those that are very dangerous andvery difficult to manage, leading ultimately to death.
