Asbestos Placques Not Compensable?

I do not know the reason however from reading some information click here I see the following:-
Pleural plaques are distinguished from other asbestos-related diseases and conditions by their appearance. These plaques can be described as white, smooth, raised areas of fibrosis collagen tissue that are found on the inner surfaces of the ribcage, diaphragm and pleura. In addition these plaques are usually calcified and can range in size from small to large.

Almost everyone who has ever been exposed to asbestos will suffer from pleural plaques. This is because the asbestos fibers work their way into the pleural lining (outer lining of the lung) where they cause chronic inflammation and eventual scarring from that inflammation. The plaques are a direct result of the pleural scarring. Thankfully these plaques are always benign in natural, and will not ever change from plaques to cancer. However, there is some current scientific evidence that suggests that any individuals that are plagued by pleural plaques do have an increased risk for developing mesothelioma.

So I can only assume that someone with this condition is not ill, only more likely to become ill. If so they could then apply for compensation.

I guess there would be a different answer if there were some treatment available to remove the plaque.
