Mesothelioma does not generally cause symptoms in the early stages.  Symptoms of mesothelioma in the lining of the lung can include11:

pain in the lower back or the side of the chest
a persistent cough
shortness of breath
hoarseness (a 'husky' voice)
unexplained weight loss
sweating
difficulty swallowing

Symptoms usually begin with breathlessness or with back or chest pain caused by a build up of fluid around the lung. This is called a pleural effusion. This fluid can be removed from the pleural space to relieve symptoms, and a type of surgery called pleurodesis is sometimes carried out to prevent fluid building up again in the pleural space. Patients can develop swelling and discomfort in the places where biopsies have been carried out, or surgery performed. Radiotherapy is now used to treat these symptoms.

A specialist solicitor should be able to get a case to court for someone with mesothelioma within 6 to 12 months. It is important that a solicitor takes a detailed statement from the person who has mesothelioma, preferably in the early stages of the illness. Only a specialist solicitor will be able to complete the case this quickly. 

You do not have to get asbestosis in order to get mesothelioma. Most people who develop mesothelioma do not have asbestosis.
