I can see it from your pov Prof and it is very sad, I'm sorry about your father. Also your uncle, LR. I didn't intend to post on this thread again but Prof's posts moved me.
Someone much older than me whom I knew very well from when I was a child died of the same maybe fifteen years back. In the construction industry, he had worked with asbestos and when it was found to be so dangerous he started a company that removed it. He didn't do the removal himself but trained people to do it and project managed jobs, checking everything was being done properly.
Every year he (and employees) underwent a thorough medical including full chest x-ray which they had to pass in order to continue with their work, that's the law. He was presumably always clear and then one year, he wasn't. He died within a few months, it was terribly sad, he'd only just retired. However he had worked with damaged asbestos for most of his working life, his exposure had been great before the dangers were discovered. By the time something showed up on medical tests the disease was advanced and that seems to be how it goes.
There was also someone else whom I knew only slightly who died from an asbestos related disease.
We were speaking of the Navy earlier, the actor Steve McQueen who died around the 1980s was exposed to damaged asbestos whilst in the Navy, which caused his death.
Engine building, boiler insulation involved asbestos and was high risk.
We will hear less of it now of course, asbestos mining was mainly a 19-20th century thing(tho' still happens in some countries). I can't begin to imagine how many miners were affected!
LR's exposure was not anywhere near being on that scale. Most people born before the 1960s have had some asbestos exposure but not for hours every day for years in an enclosed space. Still nothing to stop her having full investigations if she wants to - which she doesn't.
