The only treatment that offers any hope of a cure for mesothelioma is an operation to remove the tumour.  Unfortunately this is only rarely possible because usually by the time the cancer is discovered it is too far advanced for surgery to be done safely.

Mesotheliomas are very resistant to other types of treatment.  Radiotherapy and chemotherapy may help to ease some of the symptoms, and may sometimes even help to control the cancer for a short time but there is no evidence that they can actually increase life-expectancy and help people to live longer.

This means that mesothelioma is almost always a fatal illness. 

A number of studies have looked at the life-expectancy of people with mesothelioma.  These show average survival times of between 8 to 14 months but some people do live for a few years following discovery of the condition.

There are several different kinds of mesothelioma and the outlook does vary a little depending on the type of cancer, where it is, how far it has spread and the age of the person who is affected.  So do talk to your specialists who will be able to give you a better idea of the outlook in your particular situation.
