So most cases of mesothelioma occur in men who have worked in manufacturing using asbestos or used asbestos products, particularly in construction or engineering. The use of asbestos was very heavy in the years after the war (after 1945). Mesothelioma may not develop until 15 - 40 years after you have been exposed to asbestos, which is why we are seeing an increase in cases now. The number of cases is expected to peak around 2018 and then start to decline.
There are three types of asbestos: blue, brown and white. Blue and brown asbestos are linked with mesothelioma. They have been banned since the late 1980's and cannot be imported into the UK. White asbestos is now also thought to be harmful. The use of all asbestos was banned in 1999 in the UK.
The SV40 virus
There has been some research into a virus called SV40 (the SV stands for 'simian virus'). There is a lot of dispute amongst scientists about this and it isn't generally accepted as a cause. It seems more likely that the virus doesn't cause mesothelioma. It is possible that SV40 may help to increase risk if you've been exposed to another more major risk factor. Doctors call this a 'co-factor'. But SV40 certainly hasn't been proved to be a co-factor so far. In any case, it is far less important a risk factor than asbestos.
