Jason Williams was given less than a year to live due to exposure to asbestos 20 years prior.
"It's aggressive, very aggressive. And there is no cure, and there's no treatment. It's a death sentence," said Mr Williams.
After graduating from university, Jason began his career in IT. One of his first jobs, as a graduate in his early 20s, was at the steelworks in Port Talbot - "he loved every minute of it." "We couldn't even pronounce it. We didn't even know what it meant. And to be fair, the consultant didn't know. Because he turned to my son and he said, 'If you want to really know all about it, Google it.'"Mr Williams says the family are grateful Jason did not suffer for too long
About 85% of cases of Mesothelioma in men are attributable to asbestos exposure in the workplace according to the Health & Safety Executive.Using asbestos as a building material has been banned since 1999.It is generally considered safe if it is not disturbed.With help from his union, Unite, Jason Williams' family took legal action against the company he worked for at the time, Cap Gemini, and the current owners of the steelworks, TATA Steel.
In a statement, TATA Steel said that they were unable to comment on any specific cases that had been dealt with.
